Episode 138: Race Execution, Heat Strategy & Nutrition Lessons from Our Athletes
In this week's episode, we share the biggest lessons from recent races across the Endurance Drive community. Drawing from race reports submitted by our athletes, we dive into the common themes that separated strong performances from frustrating ones, including race-day preparation, pacing the bike to protect the run, nutrition and hydration strategies, heat management, mental resilience, race execution, open water confidence, and why racing by feel often beats chasing the numbers. We also rapid-fire five additional lessons on course reconnaissance, transitions, swim navigation, using data wisely, and how fitness transfers across disciplines. Whether you're racing a sprint triathlon, marathon, Ironman, or anything in between, there's something here to help you race smarter this season. Check it out!
One of the best parts of this podcast is passing on the wisdom gained by our community. We asked several experienced racers to pass on some lessons, tactics and strategies from their last race and when they are prepping for races. We received an incredible list of wisdom - thank you! We’ll review the most common themes.
1. Preparation beats race-day improvisation
“You do not rise to the level of your goals. You fall to the level of your systems.” - James Clear - Atomic HabitsEvery race report hits this: practice your nutrition, open water swimming, transitions, pacing, nutrition/hydration, heat exposure, and aid-station strategy in training — because race day will only let you execute what you've already rehearsed. (There is no race day magic but I wish there was!)Race week bike maintenance checks fall in here too (chain, battery, tires) — most "race-ending" mechanical issues were preventable.
Action: One of your primary goals on race day is to ‘hit the play button’, (fall to the level of your systems) rolling out all that you have practiced the last few months. You want close to zero mental friction on race day.
2. Pace the bike to protect the runMultiple athletes mentioned this principle: Half Ironman and Ironman (and we can extend this to Sprint and Olympic) racing is a run race, and your job on the bike is to not wreck that. The bike is about positioning yourself for your best run. Action: Staying conservative on power/watts on the bike, even when it feels like leaving time on the table, is what enables a strong run split later.
Insider tip: Look at your VI (Variability Index) in TrainingPeaks (if you have a power meter). For all but the hilliest of races, you want your VI 1.03 - 1.05. This means you consistently applied power in a narrow range and avoided a lot of power surges. If an athlete has a bad run, almost always their VI is greater than 1.10. (Again, some courses are very hilly so this is less applicable - see Tremblant 70.3, Maine 70.3)
3. Nutrition and electrolytes are individual, trainable variables. "You can't out-fitness a poor nutrition plan": dial this in during training and Race Sims, not on race morning.
The sodium experiment (headache-free finish after adjusting intake) and the "rolling buffet" bike strategy were mentioned a few times.
Action: Use big workouts and Race Sims to dial in your carb grams per hour, sodium (recommend ~1000mg per hour), solid foods vs liquids, water bottle carrying capacity and bottle refills/switching.
4. Heat management is a distinct skill from fitnessHeat exhaustion vs muscular fatigue are different problems with different fixes. You have to deliberately train for this and have race day tactics such as ice in the suit, dumping water, eating ice.
Action: Try to do some of your workouts and/or key sessions in the heat of the day. Bonus if you can spend some time in a sauna or hot tub for heat acclimation.
5. Mental strategy: shrink the race, solve don't panicStay process-focused rather than outcome-focused when things get hard.
Aid-station-to-aid-station thinking, stopping for 5 seconds to reset during a disorienting swim instead of spiraling, problem-solving through cramping rather than stopping — the common thread is
Action: In practice, try to put yourself in unfamiliar situations. This is nervous system training.
6. Confidence and calm are conditioning, not personalityThe open-water "conditioning vs. familiarity" point is a great example — one athlete didn't panic in cold water not because he was experienced, but because he'd specifically trained for it. Confidence shows up as the absence of fear, built from accumulated experience and nervous system training.

7. Have tiered plans (great/good/just finish) and known triggers to switch between themSeveral reports describe checking in at set points (transitions, mid-bike) and adjusting power/pacing/nutrition based on how the race is actually unfolding versus the original plan.
You might switch from Plan A to Plan B during a race (or even Plan C). Or vice versa, what might start as a mediocre race may progress to a great race! (See Katie’s point above.)
8. Data informs, feel decidesPower and HR are useful, but the recurring advice is to calibrate RPE against the numbers rather than blindly follow them — so you can still race smart if a sensor fails or the numbers say something that doesn't match how you feel.
9. The race is against yourself (until the final miles).Don't chase people early; treat the field as competitors only in the last 2–3 miles. Until then, it's pacing discipline against your own plan.
By nature, most triathlons lend themselves to individual effort. You vs you.
10. Lead with gratitude, joy and perspectiveMore than one report ends on the same note — the people, the journey, the volunteers, the fact that you get to do this at all — as the actual takeaway, regardless of finish time.

5 secondary lessons:
1. Course reconnaissance saves time and prevents surprisesKnowing the elevation profile (so you're not caught off guard by hill placement), scouting transition logistics like restroom locations, and understanding wet-road or weather risk ahead of time — small details studied in advance translate directly into either saved seconds or smarter risk decisions (like choosing safety over speed on a wet descent).
Action: Walk through transition on race morning, know all the bike/run exits and entrance. Swim backward on the race course during swim warmup, identify where the sun is, landmarks to sight on. Drive the bike course. Ride the run course the day before. Be aware of the direction of wind in relation to parts of the bike course.
2. Efficiency of movement matters as much as fitness"Slow is smooth, smooth is fast" — the idea that deliberate, economical movement in transitions and throughout the race beats choppy effort. Well prepared athletes aren't just fitter; they waste little physical or mental energy on unnecessary motion.
Action: transition practice the day before your race.
3. Swim navigation is a skill separate from swim fitnessSighting well lets you swim straighter, thread through slower swimmers, and potentially find faster ones to draft off.
Related: seeding yourself in a realistic (not overly optimistic) wave start can mean an earlier start time, which matters a lot if the run is going to be hot later in the day.
Action: Try to get in as many OWS sessions before your race. Each time you go, you will be that much closer to being ready for race day. You will improve a lot each session. These can even be short, skill based sessions of 20’ - 30’.
Get in a swim wave that is 5’ faster than your actual expected swim time.
4. Gear amplifies skill — it doesn't replace itPower meters, HR monitors, even something as small as prescription goggles — these tools only help if you've trained with them enough to interpret and trust them.
The flip side also matters: practicing pure RPE so you're not lost if the tech fails or disagrees with how you feel.
Action: do some workouts with data awareness and some other workouts without data or very little data, relying more on feel / RPE. Practice both.
5. Fitness can transfer across disciplines, especially around injuryOne athlete recovering from an ACL injury couldn't run for months, so swim volume went way up instead — and that cross-training contributed to both a faster swim and a surprisingly fast running recovery. A reminder that consistent training load (in whatever form is available) often matters more than discipline-specific mileage.
Action: Make sure your coach knows your current capacity to train and designs a plan that maximizes the time you have with your constraints.
