Kona 2018 Recap

Summary

It took me a long time to even start writing this race recap.  Beyond being busy with work, family, holidays, etc. I've had to think a lot about the race and my personal investment in this sport.  The day after the race had I announced that I was taking an indefinite period away from the sport.  I had to take the time to think about what it means to me.

Kona was my 16th Ironman start, fifth time at Kona, and 11-years since my first time racing on the Island.  It also represents the highest level of training and fitness I have ever logged, by a large margin.  While I did achieve my highest placing (6th in the age group) and fastest time on this course (9:30), I am disappointed that the performance did not reflect the level of investment in preparing for the race.  That said, I remain convinced that it's possible that I will one day reach my goals at this elusive venue.

This race recap is mostly about the race, but what underlies all of this is my love for the sport and the unending pursuit of my potential.  Further, I know that I am incredibly fortunate to have the health to even train for such a thing -- I will never forget that.  Lastly, none of this would be possible without the support of my friends and family -- thank you so much!

Race Prep

Diet

My diet was "normal" going into this race, as it had been all year long.  However, to avoid GI system inflammation, I did avoid gluten and dairy the few days prior to the race.  Most importantly, at the advice of Dave Scott, I refrained from the carb-restriction diet I typically do race-week.  This last point was a big departure for me, as I have typically cab-restricted before most of my prior Ironman races.

Swim

I only include the swim-prep because it would seem omitted otherwise.  I did nothing extraordinary for the swim prep.  I maintained the intensity and kept attending the masters group at least once per week.  While not shown anywhere, I also included several Vasa sessions.  My swim fitness was likely near where it was for most of the season.

Bike

#Dimond In the Rough

With proven bike fitness, I knew I did not need to do a great deal of work on the bike.  Nonetheless, I maintained a solid build, knowing that bike fitness could enhance my race running ability.  To this end, I wanted to achieve a higher level of bike fitness as compared to IMB.  The chart below shows the bike CTL, where I peaked out at 85 points.

What was exciting to see was that as the volume continued to rise, so did my performance metrics.  The chart below shows that my estimated VO2max kept rising substantially -- especially the bike -- after IMB.  These estimates come from the excellent Garmin Forerunner 935.  I know the estimate is reasonably accurate because I did a bike physiology test in September that demonstrated a bike VO2max of 60 mL/kg-min.  While these physiologic metrics are not extraordinarily high, the important thing for me is that my performance levels appeared to be rising -- along with the training volume.

Running

In every race of this season, I felt like my running form eluded me.  Indeed, I lost Boulder-70.3 by a mere 13-seconds due to my poor run.  However, my bike fitness and performance was through the roof.  Thus, I decided to apply some of the training principles to running that I felt were responsible for my bike performance.  While there are a few bike training themes that I think work for me, the one I wanted to apply was two big days separated by one day.  Specifically, I planned & executed two long runs separated by one day for the six week Kona build.  After IMB, I ramped the long run from 14 to 18-miles -- doing one Sunday and then another on Tuesday.  Further, these were negative-split runs, with the return effort at the high-end of IM race effort (145-149-BPM).  Indeed, I was running "back" at a 7:20-min/mile pace with a HR of 145-BPM.  I peaked my run 5-weeks out of Kona with 18-miles on Sunday & 18 on Tuesday.

Based on the gap between my run training and race performance, I wanted to up the fitness as compared to IMB.  I somewhat arbitrarily chose to increase the fitness level by 10%, as measured by the Chronic Training Load (CTL).  I peaked at a run CTL of 57 points for IMB; so, I was targeting a peak of 65 rCTL points for Kona.  As can be seen from the Performance Management Chart (PMC) below, I did hit that target peak rCTL.  Further, I maintained that level through September until October 2nd (11-days prior to the race).  As I write this, I realize that this might seem like a short run-taper, but the taper actually started a week or two prior as seen in the orange dots ramping down from a Training Stress Score of 256 (on 9/9; a 20-mile run).  Thus, the taper was more gradual with more frequent, shorter runs.

The PMC shows just aggregate training statistics, but the chart below shows more specifics.  The build, decline, and subsequent ramp in July was Boulder 70.3.  After that, the run volume and pace were very consistent and peaked at the end of August.  The pace zone represent easy (8:45-8:03/mile), IM-pace (8:02-7:22/mile), and threshold (7:22-6:40/mile) as blue, green, and red, respectively.  One can see that the majority of my run prep was at IM-specific pace.  The yellow line represents the volume in miles per week.  July through September, the average volume was between 40-50 miles per week.

Lastly, as shown previously my run performance continued to rise as indicated by the VO2max.  So, both the training load AND performance condition were rising.

General Fitness

The structure of a typical build week looked like this (starting on Thursday, as that is when the cycle seemed to start).
  • Thursday: AM 70-90-mile IM pace ride + 4-6 mile brick run
  • Friday: Mid-day swim 3k + 90-minute torque spin class
  • Saturday: AM 80-100 mile IM pace ride + 5-9 mile brick run
  • Sunday: AM long run; PM 2k swim
  • Monday: AM swim 3k + 1-hr hard spin class
  • Tuesday: AM long run
  • Wednesday: AM track workout

During the 3 months of July, August and September I had a total of four days OFF.  My general training plan simply allows me to take days off when I am tired or not performing as expected.  Otherwise, I keep pushing.  The overall PMC below shows that build, peaking at 146 CTL points -- the highest level I have ever achieved.  For reference, I peaked at 120 CTL points going into Kona 2016.


Heat Training

As it had been a mild September in Colorado, there was little opportunity to heat train outdoor.  Also, I did not have the appetite to heat-up and humidify the pain-cave.  Thus, I decided to use a different protocol -- post-workout dry-sauna sessions.  I started these sessions much farther out from the race than I typically do -- probably a good 2-months prior.  I did ~20 such sessions of at 30-60 minutes after a workout.  In addition, I did these sauna sessions without re-hydrating from the workout.  As an example, I recall several sessions after my long-run ramp of 14 to 20-miles, where I'd sit in the sauna at 140*F for 1-hour immediately following the run.  I know the body core temperature must have remained elevated, as one morning I returned from the run at 157-lb; and after the "hotbox" I weighed 154-lb (3-lb lighter than IMB18 race-weight).

In addition to the sauna heat work, I also arranged travel to arrive in Hawaii 10-days before the race so that I could acclimatize to the heat.  The day after arriving, I had planned on running 16-miles in the heat of the day.  The next day I rode 80-miles during mid-day.  The next day, I had a 13-mile run planned.  The pace was WAY off, I had to cut short the runs, and each of these training sessions severely depleted me.  It was so bad, I wondered whether I could even finish the race -- forget accomplishing my lofty expectations.

After this initial panic, I reached out to several trusted and experienced folks for advice, asking whether I should soldier-on or reel it back.  Some of the feedback helped me understand that perhaps I had dehydrated myself in these initial exposure to the heat.  Indeed, after focusing on re-hydrating (huge bowl of bone broth with lots of salt), I was back to normal the next day.

Based on this experience, it was clear to me the post-workout sauna protocol was not effective -- for me.  Perhaps this approach may work for others, but I was a non-responder.

Mental Training

In 2016 I picked up a Muse Mediation device and started using it about a month prior to Kona 2016.  As I commented in that race recap, I did not appreciate the benefits of the meditation until the chaos of the mass swim start, where I remained calm, collected, and quick -- I set a swim PR!

Since then, I have not meditated every day, but picked-up the practice in prep for some races or just to maintain some good mental training.  The most benefit I have found (with regard to triathlon) is that it is extremely useful in handling the stress of threshold sessions -- remaining calm and breathing through the intervals.  The idea of meditating in prep for triathlon may seem like a stretch, but I have absolutely found benefit in various aspects of life -- including handling ornery young kids, getting to sleep better, and pushing through physically difficult moments.  In short, it gives me another positive coping mechanism.

I resumed meditating in prep for Kona and actually achieved a new level, which required meditating for 40-minutes straight.  In addition, I logged 28-days back-to-back as I went into the race this year.  I felt I was well-prepared for the physiological challenges of this race.

Training the Gut

Historically -- especially in Kona, my GI system was the main limiter in races.  Thus, this topic is perhaps the most important of all training I did specifically for this race.  After consulting with several folks on the topic of overcoming GI distress during the race, the most common advice I received was to "train the gut".  What I had done historically was to train my body to burn fat, with MANY training sessions performed in a fasted or severely carb-restricted state.  What I had NOT done historically was trained my body to withstand a high intake during the race.  So, as part of the Kona build, I did both rides and runs using the nutrition I had planned for the race, both in quantity and type.

During the bike of races, I would normally consume ~275kCal/hr of maltodextrin-based solution.  My drink of choice had been EFS Drink, which has worked very well.  However, in order to consume even more (300+ kCal/hr), I started experimenting with adding fructose to maltodextrin in a variety of ratios, the most common being the traditional 2:1 (malto:fructose).  In the one of the big brick days, I was able to consume 300kCal/hr of this malto/fructose solution on the 4.5 hour bike.  Then, at mile-4 of the run, my lower GI felt like it was going to blow-out -- I was reduced to a walk.  At that time and throughout that , I was distraught that my "gut training" was on the wrong track -- and, even worse, I did not have a "plan-B".  But what I realized later that evening was that this "failure" was exactly what I needed.  Through this failure, I realized the main source of my GI distress during races was consuming the fructose in the Gatorade during the run.

So, my nutrition plan involved eliminating the fructose from the bike solution, which was easy and then finding a replacement for the calories on the run, which was a little bit of a challenge.  What I decided to try was carrying two EFS Liquid Shot flasks for the run, which would suffice for the first 20-miles; then use coke for the remainder of the run.

The following week, I tried this strategy consuming 300kCal/hr of EFS Pro (which worked well) on the bike.  I then started the 6-mile run with a 400kCal flask of EFS Liquid Shot.  While the racing plan was to do a shot of EFS before each aid station and wash-down with water, during this training run I had no water.  So, I ended up consuming all 400kCal within the first 20-minutes of the run.  To my surprise, my gut was solid throughout the remainder of the run!  My finding of fructose being the culprit was now verified with both a positive (failure the week before) and negative (success and absence of GI distress) cases.  My race nutrition plan was hatched!

The importance of this seemingly minor point cannot be over-stressed.  The MAIN limiter of all my IM racing seemed to be an issue of my past!  All that was left was to prove during an actual race.

At this point in the training cycle I still had another several bigger days to train the various systems.  So, I did a mix of both my traditional carb-restricted sessions in addition to "race simulation / gut training" sessions, including a 100-mile bike + 9-mile brick run.  That second big-day session worked as planned, finishing the big-day running at a 7-min/mile pace -- at altitude, in the heat (90*F).

Race Expectations

Based on my fitness level and performance in training, I was in the best Ironman condition of my life.  I had the confidence built in 2016 that I could execute a solid swim and bike at Kona.  What remained was the run.  I was setting new PRs during the long runs, while the overall raining volume continued to rise.  I was running better than ever in my life.  Lastly, I think I had figured out a nutrition plan that would keep my GI system happy.

Based on my training, I estimated the following splits for the race.  Based on historical results, these times would yield a course age group record, a first place position, or at least podium.

Race Report

Pre-race

My sister and brother-in-law (Brenda and Dave) took the kids the night before to allow an easier and early night. (Thanks again guys!)  It also allowed Christine to take me to the race site in the morning.

The plan these days is to finish (solid) breakfast 2-hours before race start.  So, I had planned on finishing near 5am.  I changed breakfast up a bit knowing that I would benefit from some extra sodium and fluids, and it helped me get out of the dehydration hole the week prior.  I had a large bowl of chicken bone broth with lots of salt.  In addition, I had two toaster waffles with Almond butter and jam.  And -- of course -- coffee!  I also took with me a large bottle of water with a serving of EFS drink to sip before the race start.

We arrived at the race venue just before 5am and established a plan where to meet after I got everything prepped.  I knew from 2016 it was going to take a while, especially body marking.  However, after getting through a narrow bottleneck leading into body-marking, I found myself through the process in just a few minutes!  Transition prep was pretty fast and I made my way out to meet Christine.  I found her as the sun was coming up and the light changed dramatically.  Simultaneously, the environment was electric, exciting, chaotic, and serene.  I was so happy to be here at this moment with Christine -- ready to take on this huge challenge.

Swim (Estimated: 0:59 to 1:02 / Actual: 1:02:45)

I seeded myself near the front (perhaps 1-guy back) and in the middle (left to right).  I kept looking at my watch to get ready for the ensuing chaos.  As the cannon boomed, we were off.  My main goal was to remain calm, keep my face in the water, and just get into a good rhythm -- while pushing hard to get ahead of the main group.  As with prior years, it was full body contact for at least 15-20 minutes.  There were periods of relative order, broken by stochastic moments of a bunch of alpha-males occupying a limited physical space.  That aside, I was able to maintain my composure.  After the turn-around, it cleared out a bit.  I knew I was swimming well because I was able to stave-off the fast female age-groupers who started 5-minute behind.

For the most part, I was able to draft for perhaps 75% of the swim.  I exited the water feeling solid and in control.

In hindsight, I am really surprised that the swim time was slower than my estimates.  I swam slightly faster in 2016, but I have consistently swam MUCH faster this year vs 2016.  Further, in the practice swim the week before, I swam a pretty comfortable 1:01.

Bike (Estimated: 4:37 to 4:49 / Actual: 4:37:30)

T1 was fast and uneventful (thankfully) -- unlike 2016!  I was expecting to come out of the water in the top 10% of the field (200 guys ahead of me), so I expected it to be somewhat sparse.  I was wrong!  It seemed like there were hundreds of people in front of me.  In fact, there were likely 450 age-groupers out of the water before me.  Based on the tracker, I started the bike in 26th of the AG.  As a result, it was "bunchy" and a little scary until we got onto the Queen-K.  My pacing plan was to hold a steady power of 225-Watts, especially in the early stages of the bike.  However, I was probably at the end of the field where it was starting to get crowded, with hundreds of guys of similar capabilities bunched together.  Some people respect the rules and try to ride legal; some just cheat and draft.  In such a circumstance if you try to ride legal and let the pelotons go ahead, you're left watching literally hundreds of guys ride up ahead of you with no end.  I'd like to say that I had thought this all through and decided my strategy of going off the front was the best choice.  However, I didn't have that forethought and did decide to stay ahead of the main peloton that kept "harassing" me.  It was clear that I had more bike strength, as the little pitches on the road would push them back, I was able to get out ahead -- but with some pretty hard surges.  Then, as the grade reversed, the group would catch me again.  So, we repeated this game all the way to Hawi (at 60-miles into the bike) and then down the descent (to 70-miles).  Finally, at this point my bike fitness allowed me to continue riding away.  It's such a great feeling to be strong when the field is thinning out and going backwards.  Looking at the tracker, I improved my position from 9th in the AG at mile 59 (turn-around) to 4th at the end of the bike.

Due to the shenanigans for the first 60-miles of the bike, I was not able to execute the bike plan.  My normalized power was 238-Watts (about 5-Watts high) and average heart rate was 141-BPM (3-BPM too high).  In retrospect that was not as bad as I thought.  

Once clear of the field, I was able to hold a more steady power.  The return power was 200-Watts (229NP), but my heart rate was rising (143-BPM; 5-BPM above plan).  I suspect the aerobic decoupling (rising HR for a even power) was a result of the rising temperature.  

Overall, I rode at 220-Watts & 141-BPM average (233NP), which is an IM PR.  This compares with IMB18 of 205AP/225NP/143BPM.  The power was about 5-Watts below plan.  Heart rate was 3-BPM over plan, which does not sound like much, but it has to come from somewhere (read on).

Bike nutrition was per plan with the first bottle of EFS Pro consumed by the time I picked-up the second (which also had 1x scoop Pre-race in it) in Hawi.  In total, it was 282kCal/hr on the bike.  The EFS Pro worked very well and I never felt bloated.  The only odd thing was, while I was drinking proactively, I did not pee on the bike.

Run (Estimated: 3:09 to 3:18 / Actual: 3:41:18)

T2 was quick and smooth.  I took a few seconds to put on the Desoto Arm Coolers to protect against the intense IR heat.  With my hand in a grocery produce bag, I was able to pull them up quickly.  I also put one of Christine's old (pink) t-shirts on my head, which covered my ears and would help keep my head wet.  In hindsight, I am not sure if that was all to helpful.

The run pacing plan was to hold a steady heart rate of 145BP, which -- on paper -- correlated with a 7:26/mile pace.  The nutrition plan was to take a shot of EFS from the flask before each aid station and wash it down with water.  As I started the run, I kept the effort in check.  However, at mile-1, I deviated from the nutrition plan -- my body seemed to want coke.  From that point forward, I allowed myself to drink coke instead of the EFS.  In hindsight, I am not sure I could stomached the gel.

I saw the family near mile-3 on the run and they told me I was in 4th of the AG.  This was the first time during the race I knew my position.  The news was neither a boost nor a drain -- I was right on plan, knowing that if I maintained the pace I could still win the AG.

Making the way to Pilani, I was smart about the hill and power-walked short sections to keep the HR down.  Once I peaked and started the little descent, I could feel the day's effort in my legs and whole-body already -- it was getting hard!  Soon after, I started to feel a little bloated and needing a porta-potty break.  At mile-12 I saw a good opportunity to take that break.  Fortunately, the break demonstrated that my GI system was operating properly (no diarrhea, which was typical by now).

At that point, the run had become really hard and I was just half-way through the marathon.  It was not leg limitation or pain, but a whole body fatigue; I was just out of energy.  With all the training I had done, all the prep, I could not believe I was in this position.  This race was not turning out how I had expected.  I did not know, but I was then in 3rd position of the AG, a position I held until mile 16.

The negative thoughts kept returning and I was not doing a good job of managing them.  At one point, near mile 16, I allowed myself to accept a lower placement.  It was a sublime resignation; I guess I did not want it as bad as I had thought.  In retrospect, this moment, this lapse, and succumbing to the negative thoughts is what haunts me, and largely defines, the race.

As we descended into the energy lab, I felt my left sock or insole bunching.  So, I decided to fix it.  So, I sat-down, pulled off the shoe and fixed whatever was bothering me -- likely something I could have easily lived with had I been in a better mental state.  It was probably due to that delay that I moved into 4th position.  As I got into the Energy Lab, I actually started walking a bit.  I'd restart by focusing on 10-breaths -- another meditation coping mechanism.

As I got back out onto the Queen-K, I took a shot of the EFS with the Pre-race in it near the mile 21 aid station.  After walking that aid station and getting the water I needed I restarted and was actually able to push the pace.  For a short while after that aid station I was actually running near a 7:30/mile pace.  However, it was not sustainable.  Regardless, things seemed to stat clicking a bit better.  I was no longer walking between aid stations.  The Pilani descent was pretty painful, but manageable.  However, when I hit the bottom I was hurting incredibly bad, but I was so close to the finish.  My first coach, Muddy Waters, saw me and told me to "stay strong".  All I could do was grimace as a slogged by.  As I made my way onto Ali'i for the last little stretch, I tried to take in the scene and sights, but I was in so much pain.  I hit the carpet, but instead of being filled with elation, I was severely disappointed.  This was the ONLY IM race in my career I've finished feeling something other than complete bliss.

As I review the run, it appears that my troubles began as soon as I got out on the Queen-K.  My heart rate started to drop and so did my pace.  The Energy Lab was a horrible section, and the return on the Queen-K was not much better.  What's also clear is that the pace was way off my training.  At 136BPM, I could normally run a 7:50/mile or so, but I was a good minute per mile slower.
  • Miles 0-7 (base of Pilani): 7:30 / 149BPM
  • Miles 9-15 (Queen-K): 8:08 / 143BPM
  • Miles 15-20 (Energy Lab): 8:57 / 136BPM
  • Miles 20-26.2 (Queen-K): 8:46 / 136BPM

What went well

  • Swim calmness -- Like 2016, while the swim start was chaotic, I was able to remain calm.  I remain convinced that meditation has improved my coping skills during stressful time such as these
  • The last 40-miles of the bike -- That portion of the race was mine to shine.  The crowds were left behind and I remained strong
  • When things went badly during the run, I kept turning to the meditation practice of counting 10-breaths -- Bad spot occur for nearly everyone.  The important thing is to establish a positive coping mechanism
  • GI distress was nearly absent on the run -- This is likely the most important advances of my triathlon career

What did NOT go according to plan

  • The swim was a good 1-2 minutes slower than I had expected  -- I cannot explain why the swim was slower than expected.  I was drafting well and swimming strong & efficient
  • The heart rate on the bike was higher than expected for the power I was holding.  Overall, it did not feel that hard, but my heart rate was 3-BPM higher than plan (138 vs 135-BPM).  Over a 4-5 hour period this additional cardiovascular stress adds up
  • I was not able to hold a steady or appropriate power for the first 60-miles of the bike due to the crowding of the course and one peloton that I kept trying to stay in front of.  In hindsight, my response to this situation probably yielded the best outcome
  • I deviated from my nutrition plan on the run -- Perhaps it was the heat, but my guy was not ready for the EFS gel.  I trust my gut over my head, so this too was probably the best course of action
  • I fell apart on the run, starting at mile-12 -- I paced the run well up until this point; so, I am still scratching y head as to the cause of this "failure"

Possible causes of the failure to race to my potential

  • Chronic over-training: Being that my training was at an all time high, I was vigilant of over-training.  My sleep was good; and I was getting a solid 8-hours a night in addition to short naps several days a week.  My weight and mood was stable.  I remained motivated to train; and, my performance kept rising.  During the build cycle, there were never any signs of over-training.  However, it was the end of a LONG season with lots of hard training and racing
  • Acute over-training: I did some pretty hard training the first three days on the island; and it put me in a pretty big hole.  I seemed to dig out quickly and fully, but that did occur just 7-days before the race
  • Over-biking: 
    • I rode with a higher heart rate at IMB18 (143BPM vs 141BPM) and still ran better at IMB; so, it's unclear whether this was the cause
    • However, as I looked across four races, including: IMB16, Kona16 (BBS estimated power), IMB18, and Kona18 a trend seemed to emerge.  As my average power rose, my run split suffered

  • Nutritional deficiency ("bonking") due to over-biking -- It's possible due to the higher normalized power that I consumed more carbohydrates than planned, which would impact the ability to run well
  • Heat Training Non-responder -- Even though I had prepared as much as reasonable, the run still felt really hot.  At this point, I am nearly out of ideas of how to handle that stress better
If you have made it this far and have some ideas on this topic, I'd appreciate hearing them!

Things I [think I] Learned

  • Fructose is my enemy
  • I can actually drink Coke as my nutrition through the entire marathon
  • The post-workout sauna sessions were ineffective in acclimatizing me to the heat of Kona
