Specialties
I specialize in building durable long-distance runners through a balance of strength, mobility, aerobic base, and psychological preparation. I help athletes build the confidence, structure, and resilience needed to take on the long challenges — whether their first ultra, a big FKT, or a multi-day expedition.
Particular specialties in 200-mile ultras, mountain races, desert running, heat and altitude adaptation, sleep deprivation, self-supported route planning, and navigating sponsorships/brand collaborations.
Philosophy
- Meet you where you are. Training should fit your life, not the other way around.
- Durability over bravado. A strong, stable body beats a heroic week of mileage. Longevity is the name of the game
- Fuel the athlete. Nutrition is training — especially above 50 miles.
- Curiosity beats punishment. Ultrarunning is exploration, not self-flagellation. Ultrarunning is an art, a discipline, and a meaningful practice
- Mindset is a skill. Confidence, focus, and self-talk matter just as much as fitness.
- Motivation is the most salient factor: making training fun, cross-training, and finding creative ways to get the miles in
- The long run is a laboratory. Every run teaches something if you’re listening.
Coaching Experience
I have been coaching a small base since 2019, from a first marathon to 200+ mile events. I coach from lived experience: years spent testing nutrition under duress, adapting to injury, rebuilding form after setbacks, and learning the psychological and physical rhythms of effort that last a day (or several). As a behavioral economist outside of running, much of my focus is on the motivational/psychological side of ultrarunning: how to build the habits that set us up for success.
About Me
I’m a San Francisco–based ultrarunner with a background in data science and economic research—someone who loves digging into the “why” behind performance as much as the miles themselves.
My ultrarunning journey started like most: curious and open-minded, following the traditional path of 50k, 50-mile, 100k, 100 mile. It escalated when, during COVID lockdown while on a research project in Bangladesh, I climbed the height of Mt. Everest on my apartment staircase—and realized endurance is as much imagination as effort.
Since then, my racing has taken me across continents, from Chile’s Atacama Desert to the mountains of China. I’m forever fascinated by how far the mind and body can go when curiosity leads the way. With wins from 50k to 100 miles and a 300-mile course record in The Speed Project, running from Los Angeles to Las Vegas in 75 hours, I believe big performances come from a place of both training and purpose, I love helping athletes—new and seasoned—build not just fitness but meaning, confidence, and joy in their running.
Big Influences
I am most influenced by Jornet, House, and Johnston’s Training for the Uphill Athlete as well as Koop’s Training Essentials for Ultrarunning and research featured in Alex Hutchinson’s Endure. Personally, I adopt a strategic carb take on nutrition, influenced by Peter Defty’s Optimized Fat Metabolism approach to endurance.
My coaching philosophy is holistic, emphasizing strength, pliability, and cross-training in addition to traditional run plans. I believe in a twofold approach to ultrarunning: the scientific and the personal. The scientific provides the basis for run plans, including periodization and aerobic zones, while the personal adapts to goals, lifestyle, and availability.
Race History
My racing resume spans wins from 50Ks to 500Ks, through deserts, mountains, cities, and everything in between. My first 100-miler I set the course record by over two hours. From there, I’ve set out to see how far I can go, taking on the country’s hardest races. I earned a podium finish at the Moab 240, my first 200+mi race, and a 10-hour shattering of the previous course record at the 300mi Speed Project, running from Los Angeles to Las Vegas in 75 hours.
I’ve podiumed in all 4 of the 200+ mile race I’ve entered, and have 9 finishes at 100 miles or more — but the real story is the transformation. Position is secondary to experience and growth. Ultras strip you down. They don’t give you who you want to be — they give you who you already are and dare you to use it.
Coaching lets me help others step into their own version of that story. Coaching lets me share some of the insight I’ve gained through thousands of miles and years of being all in on ultrarunning.

Reid Hollen –
I’ve been working with Aaron for a couple months now and can’t recommend him enough. He puts together personalized weekly plans that go beyond just running, incorporating strength, mobility, and stretching into a well-rounded training approach. I also love that he emphasizes the mental side of ultras, not just the physical. He always responds to my questions quickly and thoughtfully, and the fact that he’s competing at the top level of 200+ mile ultras shows he really knows what he’s talking about. Just PR’d in the 35K distance (1st in my age group!) after working him – onto the 50K next!
