How running a 100-mile ultramarathon made me a better medical student

Medical school has a weird way of turning time into a rumor. You sit down to “quickly review” glycolysis and suddenly it’s three hours later, you’ve memorized
exactly two enzymes, and your coffee tastes like regret. So when I told classmates I was training for a 100-mile ultramarathon, they reacted the
way you’d react if someone said they were adopting a tiger to “improve work-life balance.”

But here’s the plot twist: running 100 miles didn’t steal from my medical education. It upgraded it. Ultramarathon training became the most unexpectedly useful
“elective” I’ve ever takenteaching me how to learn, how to recover, how to think clearly under stress, and how to show up for other humans when my
own energy tank is blinking like a low-battery warning in the ICU.

The day I realized med school and ultrarunning are basically cousins

A 100-mile race is not just “a long run.” It’s a moving logistics problem with snacks. It’s hours of making decisions while tired: pace, fluids, electrolytes,
foot care, layers, attitude. Sound familiar? So is med schoolexcept the aid stations are called “clinical rotations,” and instead of gummy bears you get
a granola bar from the bottom of your bag that’s been there since orientation.

Once I stopped treating training as a competing priority and started treating it like a skill lab for medicine, the overlap got obvious:
disciplined systems, humility in the face of physiology, and the ability to keep thinking when comfort leaves the building.

Lesson #1: Time management isn’t a personality traitit’s a protocol

Early on, I tried to “find time” for long runs. That strategy is how you end up running at 10 p.m. in a headlamp, negotiating with your pancreas using
leftover cafeteria fries. Ultramarathon training forced me to schedule life like a clinic: blocks, buffers, and contingency plans.

The “micro-block” method

On paper, a 4-hour long run looks like it should ruin a weekend. In practice, it taught me to protect smaller chunks of time with the seriousness of
a sterile field. Ten minutes waiting for lecture to start? Anki. Fifteen minutes between labs? Review one concept map. I became less reliant on mythical
“free afternoons” and more fluent in small, repeatable study reps.

Progressive overload… for your brain

Training plans build mileage gradually because your body adapts in increments, not miracles. That idea translated directly to learning medicine.
Instead of cramming with the emotional intensity of a disaster movie, I practiced progressive cognitive overload: small daily increases,
scheduled review, and recovery days for consolidation. My grades improved, but more importantly, my stress levels stopped living at a constant simmer.

Lesson #2: Resilience is a skill you can train (and yes, it has side effects)

Around mile 60–70, most ultrarunners meet a version of themselves they didn’t order. It’s the point where your legs start negotiating, your stomach files
a formal complaint, and your brain begins pitching creative excuses like, “What if we simply… stop… and become a poet?”

Training taught me to recognize that discomfort isn’t always danger. Sometimes it’s just information. In clinical settings, that mindset matters:
you learn to stay calm when someone is anxious, to keep assessing instead of panicking, and to move step-by-step through a problem when the room is tense.

Grit vs. stubbornness

A 100-mile ultramarathon also taught me that perseverance is not the same thing as ego. Grit is continuing with a plan while staying responsive to new data.
Stubbornness is ignoring data because you’re emotionally attached to suffering. In medicine, that distinction is everything: you follow evidence, you reassess,
you pivot when the patient’s story changes.

Lesson #3: Evidence-based training made me more evidence-based in medicine

Ultrarunning has a tempting myth: “More is always better.” Medical students already carry a similar myth: “If I’m not exhausted, I’m not working hard enough.”
Both are false, and both have consequences.

Overtraining looks a lot like burnout (because it basically is)

I learned to watch for warning signs of overtraining: persistent fatigue, mood changes, poor sleep, declining performance, and losing the ability to enjoy
things I normally love. The body’s alarm system doesn’t always sound like sharp painit can sound like irritability, brain fog, and that eerie “tired but wired”
feeling. When I started treating those symptoms as real data, I got better at noticing similar patterns in classmates, patients, and honestly, myself.

Injury prevention is the art of respecting biology

Endurance sports are basically a long-term relationship with repetitive stress. When I ignored gradual progression, I flirted with classic overuse injuries.
Learning how stress fractures happentiny cracks from repetitive overloadmade bone physiology feel less abstract and more personal (like, “Oh, that’s my tibia
trying to email me a resignation letter.”). It also made me a more attentive clinician-in-training: I ask better questions about training load, nutrition,
recovery, and footwear because I’ve lived the cause-and-effect.

Knowing the red flags changed how I think under pressure

Ultrarunning forced me to learn what “normal hard” feels likeand what “this is not fine” feels like. For example:

• Rhabdomyolysis awareness: severe muscle pain/swelling that persists, weakness, and especially dark urine are not “grindset.” They’re medical.
• Heat illness respect: confusion and collapse aren’t character-building; they’re emergencies.
• Stress injury signals: localized bone pain that worsens with impact deserves evaluation, not a motivational quote.

In medicine, pattern recognition saves time and saves lives. Training sharpened my ability to take vague symptoms, build a differential, and act early.
It’s hard to overstate how helpful that is when you’re sleep-deprived and someone asks you to present a patient with five active problems and one mysterious rash.

Lesson #4: The humility of hydration, electrolytes, and not being weird about sodium

Before ultrarunning, I thought hydration advice was basically: “Drink water. Don’t be dramatic.” Then I learned about
exercise-associated hyponatremia, the not-fun condition where blood sodium drops, often linked to overdrinking during prolonged endurance
events. The symptoms can start annoyingly subtlenausea, headache, fatigue, crampingand escalate into confusion, seizures, and worse.

The biggest mindset shift: more fluid is not automatically better. Many modern recommendations emphasize drinking to thirst and replacing electrolytes when
appropriate, especially during long events. In the med-student brain, this was a useful correction: dosage matters. Timing matters. Context matters.
“Because it’s healthy” is not a complete plan in physiology.

Kidneys are not optional equipment

Ultramarathons also introduced me to a sobering but important topic: transient kidney stress can happen after extreme endurance efforts. I became more cautious
about factors that increase riskdehydration, heat stress, and especially casual use of NSAIDs “just to take the edge off.” That awareness carried into clinical
work: I’m more thoughtful about medication counseling, hydration status, and how easily “common” choices become risky in extreme contexts.

Lesson #5: Sleep is a study strategy (and a patient safety tool)

If medical students had an official mascot, it would be a cold burrito and a caffeine drip. But ultrarunning taught me that sleep deprivation doesn’t make you
heroicit makes you less accurate. When you’re short on sleep, your mood shifts, your attention narrows, and your working memory starts acting like it
forgot to pay rent.

In training, poor sleep showed up immediately: higher perceived effort, slower pace, worse decision-making. In med school, it showed up as sloppy recall and
a shorter fuse with everyone (including myself). Respecting sleep became non-negotiablenot because I became a perfect adult, but because I wanted to be a safer
future physician. The goal is competence, not collapse.

Lesson #6: Empathy is easier when you’ve practiced being uncomfortable

Somewhere around hour 12 of a long run, the world becomes very small: the next step, the next sip, the next checkpoint. You start understanding fatigue in a
different waynot as laziness, but as a full-body experience that shapes mood, cognition, and hope.

That helped me with patients. When someone says they’re exhausted, in pain, or “just can’t do what they used to,” I don’t automatically translate it into a
single lab value. I think about what it’s like to move through a day with limited energy. It made me more patient with slow progress, more curious about barriers,
and more likely to celebrate small wins (like walking to the mailbox without stopping) because I know what incremental progress feels like from the inside.

Lesson #7: You don’t finish 100 miles aloneand neither do you finish med school

Ultramarathons are peak community theater. Volunteers at aid stations learn your name, hand you broth, and somehow convince you that eating a salted potato at
3 a.m. is totally normal behavior. You also learn to ask for help before you’re in crisis: change socks, tape a blister, eat something real.

That translated into medicine beautifully. I got better at saying, “I don’t know,” and then doing the adult thing: looking it up, asking a resident, checking
a guideline, calling pharmacy. I became less attached to being the smartest person in the room and more attached to being useful and safe.

Practical takeaways: How ultramarathon training made me better on the wards

• Better triage: I can separate “urgent” from “loud” and keep moving through priorities.
• Cleaner routines: I plan meals, hydration, and study blocks like they’re part of the job (because they are).
• More reliable focus: Regular aerobic training supports attention and executive functionhandy when you’re juggling patient lists.
• Earlier intervention: I’m quicker to address warning signs of burnout instead of waiting for a breakdown.
• More human medicine: I’m more empathetic with fatigue, chronic pain, long recoveries, and the psychology of “this is taking forever.”

Conclusion: The finish line was never the point

Running a 100-mile ultramarathon didn’t magically turn me into a productivity robot with perfect posture and zero stress. What it did do was
teach me how to operate like a clinician: gather data, respect physiology, plan realistically, recover intentionally, and stay steady when things get messy.
That’s endurance sports. That’s medicine. And honestly, that’s adulthoodjust with more compression socks than I expected.

If you’re a medical student (or any student) thinking about a big endurance goal, you don’t need to run 100 miles to get the benefits. You just need a
practice that trains consistency, humility, and recovery. For me, the trail did that. It also taught me a crucial clinical truth:
the body keeps receipts. Treat it well, and it will carry you astonishingly far.

Extra miles: 500 more words of ultramarathon-to-med-school reality

Let me take you to the most educational part of my 100-miler: the hour when my brain stopped being a confident student and became a mildly confused golden retriever.
It was somewhere after midnight. The world had narrowed to a cone of headlamp light and the soft soundtrack of other runners’ shoes shuffling through dust.
I’d trained for distance, yesbut I hadn’t fully trained for how weird time feels when you’re awake, moving, and making decisions for that long.

At an aid station, a volunteer asked, “What do you need?” and I stared at him like he’d just requested I recite the Krebs cycle backward. In medicine, we like to
think decision-making is purely rational. In reality, decision-making is a biological process happening inside a body with hormones, glycogen stores, and a nervous
system that is not impressed by your ambitions. That night, I learned to build decision-making guardrails: simple checklists, default choices, and a rule that I
don’t make major changes when I’m emotionally spicy. On the wards, I now use the same approach. When I’m tired, I rely more on structure: verify doses, re-check
vitals, confirm the plan, and ask for a second set of eyes.

Then came the foot problem. My sock had wrinkled. That tiny wrinkle turned into a blister that turned into a full-on “why do humans have feet?” crisis. It would
have been easy to ignore it for another hour and pretend toughness was the solution. But the ultramarathon teaches a brutal truth: small problems become big ones
if you postpone care. So I sat down, cleaned it, taped it, changed socks, ate something salty, and bought myself hours of better movement.
That’s basically preventative medicine with toenails.

Around dawn, my mood lifted for no logical reason other than sunlight and calories. I started chatting with another runner who was moving slower than me. In the
past, “race brain” would’ve judged pace. But we ended up sharing strategies: how she managed nausea, how I managed low points, how we both kept promises to
ourselves in small chunks. It reminded me of patient conversations. When someone is moving slowerwhether it’s recovering from surgery, managing depression, or
learning insulin injectionsit’s not because they don’t care. It’s because their terrain is different. The job is to meet them where they are, not where you
wish they were.

The final miles were a masterclass in quiet discipline. No fireworks, no cinematic sprintjust steady forward motion and repeated choices: drink, eat, breathe,
assess. I crossed the finish line feeling wrecked and weirdly calm. Back in med school, that calm shows up when things get intense: a complicated presentation,
a packed day, an unexpected change. The ultramarathon taught me I can do hard things without turning them into emergencies. And in medicine, that might be the
most useful endurance skill of all.
