Endurance, Recovery, and Trust: What Medicine Can Learn from an Ironman

I logged 24,000 steps a couple of weeks ago, not competing, just spectating. Cheering at an Ironman turned out to be its own endurance event!

Somewhere between the cowbells and the cheers, I found myself thinking about what it really takes to sustain that kind of effort. Not just on race day and the training leading up to it, but also as it applies to other areas of life.

The Balance Behind the Drive

My future son-in-law had trained for months: data-driven, coach-guided, Garmin-tracked. His app told him when to rest and when to push harder (helpful since his mind was wired to always push more). In the final taper week, he was restless, antsy for exertion. It’s funny how the hardest part of preparation can be not working harder.

Watching him, I thought of how we live that same dynamic in medicine. We have been programmed for constant motion (showing up, producing, fixing, finishing) but often miss the data our bodies keep feeding us. The fatigue between clinic sessions. The impatience after too many demands. The subtle flatline of enthusiasm that signals we’ve been borrowing against tomorrow’s energy. The inability to fully engage with family at the end of the day.

Endurance training has a name for that balance: recovery load. Push too hard, too often, and the metrics dip. Listen, adjust, and strength follows. The same physics apply in medicine. We read patients better than we read ourselves.

The Physiology of Recovery

Progress isn’t made by effort alone. Muscles grow stronger only after stress: microtears form, the body signals to repair, fibers rebuild, and adaptation happens in recovery. Skip that phase, and the gains are lost.

The same holds true for non-physical endurance. Recovery is where clarity and creativity return. Sometimes in long stretches of sleep, sometimes in the three-minute microbreaks. Those small resets turn intensity into integration. They’re not indulgence; they’re physiology.

Trusting the Process and Staying Present

Race day wasn’t flawless. A cross-current knocked him into a buoy line during the swim; he stayed calm even when another swimmer crossed over top of him as he was untangling. Later, a twinge in his IT band from the struggle, reflecting he said “I figured it would either get better or worse and kept my focus on the bike and the amazing views. It was the most fun I’d ever had riding in a straight line.” Thankfully, it got better. He flew through transitions, fueled smart, biked through the heat, smiled and waved each time he passed us, and ran his first marathon ever, at the end.

He finished in 9:59:01 (sub-10 was his aspirational goal for his first full ironman 🎉). The final sprint, the roar of the crowd (well, the roar of our family and the nearest spectators who we let in on his goal), and 24,000 steps deep into our own endurance event, we cheered like we’d raced it too!

Watching him, I recognized that rhythm: months of preparation, then one long day of trusting the preparation and savoring the mile he was in. It’s the same before every big presentation, clinical or other training, and new initiative launches - rehearsing, refining, putting in the effort, then releasing control knowing that there will be things like the mic dying, the hijack of the Q&A session, or other unforeseen incidents.

Years ago, one of our residents had a sticker on his laptop that read Trust the Process, acknowledging that as imperfect as it is, it has taken every medical student to becoming attendings. He’d hold it up whenever tension ran high. He was right. The process: the effort, the practice, the shared learning, the micro-adjustments, and the trust built along the way - in our judgment, our teams, and in ourselves, is what carries us when the current shoves, the mic dies, or the unexpected asks for our composure.

Reflection

What helps you recognize when effort has crossed the line from productive to depleting? How might you build in recovery before it happens?

What does trusting the process look like for you right now? How might you practice releasing control without disengaging?
