Syracuse 70.3 Race Report

Syracuse was an interesting race for me on many levels.  As is often the case, when I committed to this race I had a specific plan in mind but in the months leading up to the race, the way things played out was nothing like what I had planned.  Due to minor surgery and some unrelated health issues, I didn't start my out-season program in January, I started it in March.  The result was that my out-season ended with the Syracuse 70.3 on Sunday instead of a simple 10K or half marathon.

This change did not sneak up on me, I knew what was happening and I made some changes to my plan in preparation for the race.  I adding in longer weekend rides (about 4), some longer runs (about 2) and a race rehearsal brick (56 mile bike followed by a 10K run) as well.  My out-season training plan does not include any swimming, so I added in some swim sessions, just to make sure I wouldn't drown.

I arrived in Syracuse feeling ready but with some questions lingering about my endurance.  Syracuse was never intended to be an A race for me, so I was in the right place in my head and I was comfortable treating the day as more of a fitness test than a race.  My A race this season is IRONMAN Arizona in November, so regardless of what I learned on Sunday I have plenty of time to react and adjust.


Syracuse is only my third HIM and from a course layout perspective, it's probably the most challenging.  My most recent HIM was a very windy day on a very flat course at Cedar Point in 2013.

All tuned up and ready to race!
Part of the "deal" on entering Syracuse was that it coincided with a family reunion weekend for my wife's family in up-state NY.  As a result, we loaded up the car and hit the road for Lowville, NY immediately after work on Thursday.  That's about a 7 hour drive with the requisite stops for gas, food, bathroom, etc. so we pulled into the hotel parking lot at about 1:00 AM Friday morning.  Friday and Saturday morning were dedicated to NY family and friends, which was great fun.

Welcome to the village!
I left for Syracuse around noon on Saturday knowing that would give me plenty of time for race check-in, transition setup, dinner and a good night of sleep.

No line for all world athletes. Sweet

My corner of transition
Race morning was pretty uneventful.  My swim wave started at 7:36 but transition closed at 6:55 and I had heard horror stories about traffic, so I got up at 4:15, got breakfast and got on the road by about 4:30.  I didn't hit any traffic and I was parked by 5:00 or maybe 5:15, so I set the alarm on my phone and went back to sleep in the car until ~6:15.

I woke up in a driving rain, so I hung in the car for as long as I could before I headed out to pump tires, add bottles and arrange my transition space.  I think I went into transition at 6:45 and I was back out and in line for a porta john by 6:55.

At least the rain stopped for the race!
SWIM
I warmed up a little and then got back out of the water to join my group in line for the start.  I'm not a big fan of the wave start, but I understand that the lake is really too small to support a mass start with that many people.  I had no trouble finding a clear lane but the smaller group makes it harder to find feet and also other people to sight off.  There was not too much contact during the swim, except that I did get kicked in the thumb.  This actually hurt for about a week, but it's better now.

Both of the turn buoys were clear and overall the swim was pretty uneventful.  I was least prepared for the swim, having only been in the pool 6 or 7 times prior to the race, so I was pretty happy to come away with a 41:56 which is a PR for me.  What can I say, I'm a slow swimmer.

Look at that focus
T1
Transition was slow.  I had to stop for a wetsuit stripper, who had trouble getting the wetsuit off of my feet.  Then I had some trouble with my bike jersey and finally, there was quite a bit of distance to cover from the swim out to the bike mount.  My goal time was 4:00 and my actual time was 6:08.

Bike
I was really excited about the Syracuse bike.  I've been doing a lot of climbing as part of the out-season plan and the "rolling hills" that everyone talks about at Syracuse sound like home to me.

The Syracuse course starts with a mile or two of fast flat followed by ~10 miles of serious climbing.  My heart rate coming out of T1 was high - really high actually - so I soft pedaled those first few miles to try and bring it down.  Once the hills started, I tried to keep a lid on my power output, but that was hard given the steep and long hills.  By mile 15 the biggest hills were behind me and I was able to settle back to my planed power output.

Thanks to a friend's prerace ride and forum post, I took the time to drive the course on Saturday and that was a smart move.  I shifted early in several sections and skipped the whole "wrong gear" and "dropped chain" drama that many others endured.  I think I counted at least 5 or 6 people who started into steep climbs in the wrong gear and either dropped a chain or simply had to stop to recover.

Actually looking where I'm going - winning
Overall I worked a little harder than I wanted to but not so much so that I did any damage.  My goal time was anything under 3 hours and my actual time was 2:55:33. What's interesting about this time is that I was at 1:34 at the halfway mark of the ride, so my second half was something like 1:21, which is really fast for me.  The second half of the ride was net downhill and my times prove that.

The look of pain
Run
As usual, your day always comes down to the run and even more so in my case as 1) I came in with questions about my endurance and 2) I rode harder than I planned.  Not to worry though, it all worked out in the end.

My heart rate did continue to settle over the duration of the bike, so I was curious to see what would happen as I started running. Coming out of T2 I set out at my planned pace, but I kept a close watch on my heart rate.

If you've not seen the Syracuse run course, it's really something.  As in, I'd like to meet (and punch in the face) the person who set it up.  It's filled with grass and mud and absurd hills, and then you get to do it all again!  I reminded me of a High School cross country course.

Yikes
What this meant was that it was hard to pace and it was hard to judge my overall effort.  Some miles were fast and others slow so I just tried to stay cool and smart.  I held back a little on the first "out" leg, since the out is mostly up hill and then I bumped things up on the "back".  I notched up again on the second "out" and then I notched up much more aggressive on the second "back".  This plan worked for me as I managed to speed up quite a bit on that second "back" leg and I negative split both of the measured splits on the second lap.

It was pretty hot and humid out, so I used my transition ziploc bag for ice during the run.  This gave me access to cold water and ice between aid stations and that was really helpful.  

Looking strong!
My goal time was anything under 2 hours and I ran a 1:57:24

Overall my goal time was anything under 6:00 and I went 5:44:05.

My best ever HIM is 5:35:27 (Cedar Point) so no PR today but given where I am in my season and the challenges I've overcome from a training perspective, I'm really happy with this result.  I'm also especially happy with my run execution.  The hills were soul sucking, many people walked them, so the fact that I was able to power-shuffel through them withoug blowing up really made me happy.

Hopefully you had a great day for your last race!

Technical and nutrition details
BIKE
I consumed 5 gels and ~8 scoops of Skratch Labs SDM (~128oz) for a total of 1140 calories and 3130 mg of sodium.

There are too few aid stations on the ride.  I anticipated this and adjusted accordingly.  If I would have raced only with on-course nutrition, I would have come up WAY short on hydration.

Bike Power:
Bike NP - 192
Bike IF - 0.87
Bike TSS - 220

RUN
Over the entire run I consumed 2 gels, 2 salt tabs, lots of gatorade and just a bit of coke.

2014 IRONMAN Arizona. Different. Good.

Forty-two miles into the IRONMAN Arizona bike, I was in a dark place. My back and neck were on fire and consistent head and cross winds were wreaking havoc with my well-formed race plan. My inner dialogue was sour and getting meaner by the mile. "Why are you here?" "What are you doing?" "You're letting yourself down!" "Racing-self honors training-self, it doesn't screw him over!" Long gone was the magic of an IRONMAN day and the elation of a near 15 minute swim PR. All I could see ahead of me was the meager power number on my Garmin and about 20 feet of windblown blacktop.  All I could think about was that at this pace, I was going to be on the bike all freaking day.

















Sixteen months earlier, riding high after my first IRONMAN finish, I registered to be a volunteer for the 2013 version of IMAZ.  Four months after that, I flew to Phoenix and spent a gorgeous day in the Arizona sun, helping strangers on their IRONMAN journey.  Sixteen months is a really long time to think about and work towards something.  Hell, I got engaged and then married in less than six months!



So 16 months can add up to a lot of weight and expectation riding on your shoulders. A lot went down in that time - thousands of training miles, another IM finish and some major life events.  On top of all of that, this IRONMAN was supposed to be "different" than the previous two.

Different how, you ask? Well that's an interesting story. As I was preparing for my first attempt at IRONMAN I stuck to the vague, "I just want to finish" goal that, I expect, defines most everyone's first IM start.  Actually, it became something of internal joke.  When I thought about IM and race day, I would often ask myself, "I wonder how many times you have to line up before 'just finish' isn't the primary goal?"  Going into IM number two, "just finish" was still on my mind.  Sure, I had thoughts, hopes, dreams about what a great day might look like and I had specific execution plans, but "just finish" was there, in the front of my mind, as a primary goal.  And again, as I was typing up my race plan for IM number three I actually included my inner monologue as an open question to the group that I train with.  It read something like this:
IMAZ Goals and Goal Times
As always, my number one goal is to finish.  I’m curious, can anyone tell me when (if) this will stop being the number one goal?
I did follow that up with some execution based goals, but "just finish" was out there, in writing, just waiting to EXCUSE the pain and the suck that comes with IRONMAN.  Sure, my race plan read, I want to go faster than I went before, but my primary goal is to "just finish".

Fortunately, some very smart and perceptive people read that and immediately called bullshit!  They pointed out that I had worked too hard to be satisfied with finishing.  They pointed out that IRONMAN is hard and "if you're content with just finishing, then it's real easy to give in to the overwhelming urge to just trot along for the last two hours".  The key to racing IRONMAN, they said, is making every mile of the back half of the run feel like it's harder work than the previous mile.  This is the only way not to slow down and this is not consistent with a just finish mindset.

So I revised my goals and for the first time in my IRONMAN journey, just finish was nowhere to be found. 
IMAZ Goals and Goal Times
This is the race where I want to race to my proven capability and show why I've been doing all of this work.  To make that happen, I have specific goals around execution: I want to stay in my box, ride my numbers, remain patient and disciplined, push the suck out as far into the run as possible and when the suck does start I want to feed on it and turn it into a source of motivation and energy.
Different.  Scary.

And let's just say that plodding along at 10 MPH into a kickin' headwind, making meager watts was nowhere on my goal sheet. So yes, I was being hard on myself, looking for motivation, trying really hard not to spoil something that had been so long in the making, something that was going to be different.



For a day that was supposed to be different, it started just like any other.  I got through my morning routine, loaded up my bike nutrition, dropped my clothes with Cath and worked my way up the line towards the swim stairs. I was excited and the weight of the day was nowhere to be found. This would be my first wetsuit assisted IRONMAN swim and I was pumped about that. I'm not a good swimmer, this is no secret, so I was hopeful that the wetsuit would help me to overcome some of my swimming quirks.  The morning was beautiful and seeing the sunrise from the water was something new. I think there was some sort of traffic jam getting everyone into the water and it seemed like the cannon did not go off at 7:00.  Regardless, it did go off and the water went crazy - all thrashing arms and kicking legs - but eventually it settled out into a typical, crowded, IRONMAN swim.  I felt strong and fast all the way to the first turn, which appeared before I even had time to wish for it. I focused on form and rhythm and I noticed every time that my legs dropped deep into the water.  This was new for me and it reinforced my focus on form.


The first turn was a crazy mass of humanity and so was the second. I found some clear water on the way back but I also had some navigation issues and ended up swimming a zigzag pattern between the markers. My back started to get a little sore, but before I knew it, I was making the third turn and the stairs were in sight.  I was careful getting out of the water and nearly tripped climbing the stairs to shore, but that didn't keep me from smiling when I saw 1:18 on my watch.  My perfect-day swim goal was 1:25.  My previous best was a 1:33. Different. Good.

Transition went by in a blur and I pedaled out of the park and off towards the desert.



One of the final, critical, elements of the training program I follow is the idea of the "one-thing".  Somewhere in the IRONMAN run, the program says, your brain and your body are going to disconnect and start to argue. Body says to brain, "Hey brain, this sucks, why are we out here? Hey brain, you better have a damn good answer or I'm going to slow us the hell down." The one-thing is your rehearsed answer, the f-you body, I'm the brain and what I say goes. At that critical moment and for many moments after, your one-thing is all that stands between you and slowing down. So I've done my homework, I have my one-thing all prepared and rehearsed and ready to go.  Actually my one-thing has been with me all through my training and preparation, on my mind, every day.  The hitch is, I think to myself, your one-thing is for the run and you're not even halfway into the bike!

The bike breaks down into 9 mile increments:
Administrative bullshit out of town towards the beeline. Aimless. Shifting winds. Disappointing power numbers.

The beeline out. Head down and power up. More determined. Eat, drink, stretch and repeat. Yell at the asshole who spent 10 minutes on my wheel. Laugh as he passed me and immediately sucked up behind the next guy.

The beeline back. Pee. Maintain power. Eat and drink more. Laugh after hearing "1659 (not my number) four minutes for drafting" and seeing the official ride away on the back of the motorcycle.

More administrative bullshit back into town. Listless. Lose a water bottle. Worry about getting dehydrated. Wonder if there will be 500 flat tires today or maybe 1000.

Repeat... Three fucking times! (in my best Robin Williams, Scottish voice)

I've never been so happy to get off of the bike in my life.  But somehow, I've never felt as good coming off of the bike either. I don't know if the difference was the long downhill back into town or the fact that my overall effort was lower than expected or maybe it was the low humidity and the fact that I was dry. Of course it could be that I spent the last 70 miles thinking about my one thing.

My one thing is my dad.

Like many fathers, mine had a strong and positive influence on my life. He was always an athlete and an adrenaline junkie before that term was even coined. But more than anything, he was a runner and a cyclist. As a young teenager, I remember him qualifying for Boston, in his first and only marathon, by running a 2:53. As an adult, I remember him pulling me along, on his single speed, on my first group ride after getting back into cycling, post college and kids and adult life.

He was diagnosed with prostate cancer at 55, I was 29. He lived with cancer for almost 20 years but he didn’t let cancer define him, instead he defined himself through the people he helped and the causes that he supported. He was actively involved with Habitat for Humanity, Animal Friends, Cyclists Combating Cancer and Spokes of Hope. At one point he was even a grant reviewer for the Livestrong Foundation.

He and I got to share the memory of my first IM finish, but he passed away last October, before I went to IMAZ as a volunteer and before my second round at IMTX. I thought about him a lot in Arizona last year, as I was helping others on their IRONMAN journey. He would have enjoyed that; spending the day outside helping other people achieve something special.

Training and racing IRONMAN keeps his memory strong for me. This is the sort of challenge that he respected and appreciated. When things get tough, his memory always gets me through. Honoring my father for all that he was and continues to be, that’s my one thing.

And that's where I went at mile 42, as the walls were collapsing in and the lights were going dim.

The bike was a challenge for many people that day and more than a few ended up overcooking themselves.  In my age group, two of the first five people off of the bike ended up DNF and seven of the first 25 off the bike ended up falling 25 places, or more, during the run!  But don't worry, my story has a happy ending.  All of my mental gymnastics aside, my dark place was rooted in the fact that I knew I could go harder, that I should have been doing more.  And the fact that I was doing less? Well, that set me up for some magic on the run.

For those few who care, I rode a 6:07:xx with an IF of 0.67, a VI of 1.03 and a TSS of 280, which looks like perfect execution, save the fact that I trained to hold an IF of 0.71. 

I ran through the grass in my socks and took my run bag from the volunteer - "Thank you!"  I dumped the bag, put on my shoes, picked up the ziploc bag full of all of my small crap and started running.

Cath, Elizabeth, Jenna, Gemma and Arty were all waiting just past special needs.  Seeing them was a real boost.  Lizzie ran with me all the way to the team tent and we talked about the bike and how beautiful the day was.  I waved at coach and everyone else in the tent and then I just ran.

“Most people never run far enough on their first wind to find out they've got a second. Give your dreams all you've got and you'll be amazed at the energy that comes out of you.”
-William James

I love to run. I get to retreat into the quiet place inside my head; to be alone with my thoughts and dreams. Running helps me to see past the distractions, past the energy and the pain, through to the passion that’s required to achieve my dreams.

Over the course of this season I’ve built a deep internal energy reserve by logging countless hours and miles in the heat, the cold, the rain, the “whatever came my way”.  That reserve and I have been dating for the last 12 weeks, getting to know each other, sharing secrets, pushing boundaries, messing up and then cleaning up after.  We know each other like family and my marathon plan was to use that knowledge to extract every ounce of energy I’d spent the previous year depositing.  The reality though, is that I knew it was going to take more than my own energy reserves to get me where I wanted to be.  It was going to take a second wind and maybe a third and so that’s what I planned to give.

There is nothing quite like an IRONMAN marathon.  You reach deep into that reserve and test yourself. You suck energy from the crowd and push yourself. You go back into your reserve, dig deeper, push yourself further and harder. And then it happens, you get to the place where you’re faced with the decision to keep going or to quit. Many people pass that point without knowledge or acknowledgement, they simply slow down. Some, myself included, realize that they’ve passed that point but are unable to do anything about it.  You just get slower. You know it, you think about it, own it, try to change it even, but the seconds tick by faster than the miles.

I’ve run all the way in my previous IRONMAN marathons but both times I’ve fallen victim to the slowdown. This time the goal was to be different. This time I planned to find something else, anything else that I could draw from to be able to maintain pace. Of course part of this comes from careful planning and dedicated execution. But the other part has to come from within. Don’t slow down. Different. Good.

My first six miles are at LRP plus 30 seconds. The idea is that those six miles and the extra three minutes give your body time to regroup. Time to get past the pure joy of NOT BEING ON THE BIKE! Time to settle out and find the right pace. Those first six miles felt like I was crawling. It took everything I had not to sprint off out of transition and bang-out a couple of 8 minute miles. Fortunately I forced myself to stick to the planning and execution goals that I spelled out leading up to the race.

After mile six, the 30 second cushion goes away and I have to push the pace to LRP. This actually felt pretty good and my splits dropped exactly like I wanted. Miles seven – thirteen passed without incident, at LRP, and the suck stayed at bay. Miles 14 – 18 got progressively harder as I finished off my first wind and started into the second, but I was holding pace. Miles 19 and 20 are on the far side of the lake and are slightly downhill. The downhill helped, but these miles were hard.

I held pace. Miles 21 and 22 are out and back, slightly up hill and then slightly downhill. Again, I held pace.

Mile 23 has the only significant uphill on the entire course. Holding pace here would be a major victory and just might provide the emotional lift, the third wind that I would need to finish like I wanted.  Dig deep, hold pace. Mile 24, downhill and then back up, fast and then slow, but faster than the mile before – holding pace. Mile 25, downhill across the bridge, towards the finish. The reality starting to settle in, as fast as the mile before, holding pace. Mile 26, around the corner towards the finish chute. Energy left. Faster than the mile before. The picture becoming more and more clear by the stride.  Finally, the finish line in sight, the emotion breaking through, the dream realized. I didn’t slow down. I DIDN’T SLOW DOWN!



From the course splits:

Lap1 Lap 2
0:17:55 0:17:41
0:17:57 0:17:12
0:13:44 0:13:24
0:24:25 0:24:13
0:19:21 0:19:31
0:11:05 0:10:53
0:16:26 0:15:17
2:00:53 1:58:11
Run: 3:59:04

I've never run a standalone marathon, so this is the first time that I've run a negative split and it's the first time I've ever run under four hours.

Overall - 11:32:xx, which is 29 minutes faster than my previous best.

So, I've been sitting on this race report for so long I've almost given up blogging all together. I'm not really sure what happened or why but it just never quite seemed finished.  Or maybe I just didn't know how to finish it.  This is supposed to be the part of the story where I talk about how this race changed me, about how everything will be "happily ever after" because I had a great day during IRONMAN.  Of course I don't believe that, but I'm happy that I got to spend the day with friends, family and the memory of my dad.


And I'm happy that I doubled down and decided to go again...

Just How Much Does This Poor Swimmer Benefit From a Wetsuit?

I’m not a swimmer, I think by now we all know that.  I don’t (well, didn't) own a wetsuit.   I've rented one (from wetsuiterental.com) a few times for HIM races but I've never worn one in a full distance IM race or swim.  Of course, this year will be different as IMAZ should be wetsuit legal, so that had me thinking about wetsuits and wanting to swim in one before Arizona.

Long story short, I rented a wetsuit for a race this past weekend but then ended up skipping the race. So on Monday night I did the bottom third of my scheduled swim workout wearing the rental suit. I figured that would help me confirm the fit so I could ask the rental company for the same exact suit for Arizona.

Prior to Monday, I had worn a wetsuit while swimming exactly four times, twice in a pool to test fit and twice in HIM distance open water swims. It had been over a year since the last time I wore one and I had no specific memory of the previous pools swims: they were unremarkable.

That was not the case on Monday. My previous “fit swims” were during taper so maybe this is the first time I've really worked out in a wetsuit, I don’t know, but what I do know is I was markedly faster in the pool while wearing the suit.

I know, this is a duh type of comment, but this is the first time I’ve really noticed the benefit and it’s the first time I have actual data to support my feelings. The rest of this post will focus on the data that I have and the conclusions that I’ve drawn from said data.

But first, I will start with a disclaimer. This was not a scientific study and I’m not here trying to pass it off as one. This is one set of data that I collected during a regularly scheduled swim workout. I did not design the workout with the idea of testing the benefits of a wetsuit; I simply wore the suit for part of the workout that was on my plan for Monday. I know that I was swimming 150s without the suit and 100s and 50s with the suit, that’s what was on my plan. This is nothing more than data that I collected and that I found interesting; your mileage may vary. If you’re looking for a scientific study of the benefits of a wetsuit, try reading this great article - The 2013 Triathlon Wetsuit Performance Test, by Aaron Hersh, published Jul 30, 2013

So with the disclaimer out of the way, let’s get on to the data.

The wetsuit:
A Blueseventy Fusion, full-sleeve.  Size M/L. For reference, I’m ~5’11” and 175 lbs.

The Scheduled Workout:
  • 200 WU
  • 6x200
  • 8x150
  • 7x100
  • 6x50
  • 200 CD

Notice first that I’m a slow swimmer. Also notice the significant change in pace between the last 150 and the first 100: this is where I put on the wetsuit. I know, if I were to design a study to measure the impact of wearing a wetsuit I would compare across similar lap distances, but this is the data that I have and it’s still interesting.

Here is the chart split out to focus on the last 1200m that I swam without the wetsuit. Again, I realize that these are all 150s but this is the data that I have.

Interval Time Pace (/100 m) Strokes Stroke Rate (/min) Stroke Distance (m) SWOLF Efficiency
150m Freestyle 03:07.8 02:05.2 76 24.3 2 44 44
150m Freestyle 03:12.4 02:08.3 77 24 1.9 45 44.9
150m Freestyle 03:13.3 02:08.9 75 23.3 2 45 44.7

AVERAGE 02:09.4 1.9 46 45.4

Now here is a chart split out to focus on the last 1200m with the wetsuit. Yes, I realize that these are mostly 100s and 50s, not the 150s I swam above. I also want to point out that these splits represent meters 2700 – 3900 of what, for me, is a long swim.

Interval Time Pace (/100 m) Strokes Stroke Rate (/min) Stroke Distance (m) SWOLF Efficiency
100m Freestyle 01:48.3 01:48.3 48 26.6 2.1 39 39.1

AVERAGE 01:48.7 2.1 39 39

Notice the average stroke distance in the first chart as compared to the average stroke distance in the second chart. This is the measured benefit, to me, of the wetsuit during my swim.  

Here is a summary chart:


Interval Pace (/100 m) Stroke Distance (m) SWOLF Efficiency
AVERAGE (without) 02:09.4 1.9 45.5 45.425
AVERAGE (with) 01:48.7 2.1 39 39
Percent Change -16% 11% -14% -14%

Overall I saw an 11% increase in distance per stroke! It’s not the 18% increase reported in the article above, but I’ll take it, and actually, I did. Instead of returning the suit to wetsuitrental.com, I bought the suit and hung it up in my closet!

If I decide to wear the suit during a race rehearsal, maybe I’ll come back and update this post.  My only hesitation with that is how warm they keep the pool where I usually swim.  A 90 minute swim, in a wetsuit, in an 82 degree pool sounds like a bad idea to me.

Now it’s time to rethink my swim goal for IMAZ!
