Foundry Files No. 005: The Adaptation of Adversity

Ironman Lake Placid 2024 was supposed to be a confidence-builder.

It was my final Ironman before heading to Kona for the Ironman World Championship, and the goal was simple: execute a strong race, build confidence, and continue carrying momentum into the biggest race of my season.

Instead, it turned into a survival test.

Not long into the bike ride, I felt something I had dealt with earlier in the season that forced me to DNF at IM Texas. My back began tightening up significantly, and as it did, my legs followed. They felt stiff, heavy, and achy far earlier than they should have. Within the second hour of the race, I knew this wasn’t going to be the day I had envisioned during months of preparation. At that point, I had a choice to make.

I could spend the rest of the day frustrated by the race I wasn’t having. I could focus on the watts I wasn’t producing, the splits I wasn’t hitting, and the outcome that was slowly slipping away. Or I could accept the reality of the situation and adapt my expectations to the race that was unfolding in front of me.

I chose the latter.

The goal shifted from performance to execution. Instead of chasing a specific result, I focused on making smart decisions, managing the situation, and getting everything I could out of the day. It wasn’t my fastest race. It wasn’t my prettiest race. It certainly wasn’t a personal best at Lake Placid.

But I finished, and more importantly, I learned.

This was me on the ‘run’ course… on this day I did probably about equal parts running and walking.

A few months later, I would go on to race a sub-10-hour Ironman at the World Championships in Kona, HI. Looking back, Lake Placid wasn’t a setback. It was preparation. The adversity I experienced there forced me to practice a skill that every successful endurance athlete eventually has to learn: adaptation.

Because the reality is that endurance sports rarely reward the athlete who can execute the perfect plan. More often, they reward the athlete who can continue executing when the plan begins to fall apart.

The Myth of the Perfect Race

One of the biggest misconceptions in triathlon is that successful races feel good from start to finish. They don’t.

Some of the best races you’ll ever have include moments of doubt, discomfort, uncertainty, and frustration. You might feel flat during the swim. You might struggle to settle into your goal power on the bike. You might start the run convinced you’re about to have a terrible day.

The mistake many athletes make is assuming that these feelings mean something has gone wrong. In reality, discomfort is often just part of the experience. Racing is supposed to be difficult. That’s what makes it meaningful.

We spend months preparing for races under controlled conditions. We know our routes, our equipment, our nutrition plans, and our pacing strategy. Then race day arrives and introduces variables we can’t fully control: weather, competition, course conditions, mechanical issues, and unexpected sensations in our own bodies.

When reality fails to match expectations, many athletes panic.

The athletes who perform at their highest level don’t necessarily avoid these moments. They simply respond to them in a different way. They understand that racing is not a test of perfection. It’s a test of problem solving under fatigue.

Your Brain Is Part of the Race

One of the ideas that has always resonated with me from Matt Fitzgerald’s How Bad Do You Want It? is that endurance performance is never purely physical.

Every race is a negotiation between the body and the brain.

As effort increases, your brain is constantly evaluating the situation. It assesses discomfort, fatigue, environmental conditions, motivation, and perceived risk. Long before you reach a true physiological limit, your brain often begins searching for reasons to slow down, back off, or become more conservative. That’s not weakness. It’s protection.

The challenge is that the sensation of reaching your limit and actually reaching your limit are often two very different things.

Think about how many times you’ve convinced yourself a workout was going terribly, only to finish stronger than expected. Or how many races have felt awful early before turning around later. The body often has more available than we think. What changes is our willingness to continue engaging with discomfort.

The best endurance athletes aren’t necessarily better because they suffer more. They’re better because they’ve learned how to interpret suffering differently.

They don’t immediately assume adversity means failure. They understand adversity is often just part of the process.

Adversity Is an Adaptation Opportunity

Most athletes think of adaptation in purely physiological terms. We train. We recover. We get fitter. But some of the most important adaptations in endurance sport happen mentally.

  • Every difficult race teaches lessons that perfect races never could.

  • Every workout where conditions are worse than expected teaches flexibility.

  • Every missed session teaches perspective.

  • Every mechanical issue, nutrition mistake, weather challenge, or pacing error creates an opportunity to improve decision-making.

This is one of the reasons I actually appreciate difficult races more now than I did earlier in my athletic career. Perfect races are validating. Difficult races are educational. And education tends to compound when validation doesn’t.

The athlete who only performs when everything is perfect becomes fragile. The athlete who learns how to adapt becomes resilient. Over the long term, resilience wins.

Why Triathlon Rewards Adaptability

Few sports expose athletes to uncertainty like triathlon. Three disciplines. Variable weather. Equipment. Nutrition. Hydration. Transitions. Competition. Terrain.

There are simply too many moving pieces to expect everything to go according to plan. That’s why some athletes spend entire races fighting reality.

The swim is rough, so they become frustrated. The bike power isn’t where they want it, so they force it. The run starts poorly, so they panic.

Before long, they’re spending more energy resisting circumstances than responding to them. The athletes who race well understand that adaptability is part of the sport itself.

They stop asking:
“Why is this happening?”

And start asking:
“What’s the best decision I can make right now?”

That’s a powerful shift. Because once you stop wishing for different circumstances, you can start making progress within the circumstances you have.

From the Foundry Floor

One of the most common mistakes I see athletes make is treating adversity as evidence that something is wrong.

  • A workout goes poorly and suddenly fitness is gone.

  • A race doesn’t unfold exactly as planned and the athlete immediately begins rewriting the story of their season.

  • A rough swim, missed bottle, hot day, mechanical issue, or difficult stretch on the run becomes the defining moment of the race instead of simply another obstacle to navigate.

The reality is that endurance sports are messy. The athletes who consistently perform at a high level aren’t the athletes who avoid problems. They’re the athletes who refuse to let one problem become multiple problems.

  • A bad swim doesn’t need to become a bad bike.

  • A bad bike doesn’t need to become a bad run.

  • A difficult race doesn’t need to become a bad season.

The ability to adapt is one of the most trainable skills in endurance sport, yet it’s rarely something athletes intentionally work on. When I look back at the athletes who consistently exceed expectations, the common denominator usually isn’t talent.

It’s resilience. And not the social media version of resilience. The real version. The ability to continue making good decisions when things aren’t going according to plan.

Closing Thought

Looking back on IM Lake Placid 2024, I don’t remember the bike power. I don’t remember the splits. I don’t remember exactly how much time I lost because of my back.

What I remember is the decision. The decision to stop fighting reality and start working with it.

At the time, it felt like a disappointing race. In hindsight, it may have been one of the most valuable races I’ve ever had. Because endurance sport has a way of teaching the same lesson over and over again:

  • Conditions won’t always be ideal.

  • Your body won’t always cooperate.

  • The race won’t always unfold according to plan.

The question isn’t whether adversity will show up. The question is whether you’ve developed the ability to adapt when it does. And in many cases, that’s what ultimately separates good athletes from great ones.
