“I help triathletes and endurance athletes train with more efficiency: smarter structure, fewer injuries, better execution.”
I’m Frederic Simon, founder and head coach at Yousuli. I coach triathletes and endurance athletes using a mix of sports science, biomechanics, and behavior change, so your training creates speed without wasting time.
The boxes ticked. The deeper work shows up in how the plan looks for you.
Certified triathlon coach with specializations in short-course, long-course, youth, and paratriathlon.
Ironman University coaching certification, long-course training methodology and race execution.
Structured training planning and load-management with the gold-standard endurance platform.
Strength and conditioning focus on movement quality, load tolerance, and injury-aware progressions.
Specialist credential in fueling for training, racing, and recovery, pairs with the Yousuli Performance Lab RMR work.
Cognitive-behavioral approach to building habits, managing setbacks, and the actual psychology of staying on plan.
Some moments don’t define you, but they shape how you see the world.
It would be a mistake to tie your identity to one event, but some moments do change how you see the world.
When I was about six months old, I fell into a pool and was found about five minutes later. I survived by pushing off the bottom to breathe. For years, the wall of that pool was the only thing I dreamed about.
Later, I grew up extremely active and found my way into sports: swimming, skiing, riding, and combat sports.
Perhaps because I didn’t feel protected from danger as a child, I learned early to look for freedom elsewhere, and built tools to cope with hardship and SA. I chased adventure and, when I could, escaped into the wilderness.
As a teenager I set out to travel, and those years shaped me more than any plan ever could, through good and bad experiences across India, China, Canada, and much of Europe.
After about ten years in martial arts, including two years training in a remote village in China, I began coaching MMA and self-defense in 2005 at BLCU (Beijing).
My love for combat sports never changed, but the move into endurance sport showed me something important: it can be both therapeutic and widely accessible. Since then, I’ve stayed on a simple mission: keep learning, so the people I coach waste less time and get better outcomes.
I’ve always been more drawn to training than racing. I like long projects that test biomechanics and the limits of the mind. In 2015, I completed a marathon every week across China and was featured in a national documentary.
During the COVID years I took on the 7030+: 1.9 km swim, 90 km bike, 21 km run, repeated for 101 consecutive days. I’ve crossed seas in open-water swims (Italy to France, the smaller but mythical Galilee). And there will be more along the way.
Two decades of coaching, racing, documentaries, welfare projects, and challenges, a non-exhaustive list, in no particular order.
30-min national-network documentary following a marathon-a-week project across China. The project itself was the real gift: 52 marathons across 52 host cities, plus at least twice as many cities again from the travel around them, hundreds of people, and a year of experimenting on the road with strength & conditioning and running mechanics.
1.9 km swim, 90 km bike, 21 km run, every day for 101 consecutive days. I was eating almost non-stop and still finished at 5 to 6% body fat. Emotionally a real roller coaster. Photo: day 101, in a Superman outfit gifted by a local boy.
Two separate efforts, not one. The E-everesting (8,848 m of climbing on a stationary trainer) was one ride. The 1,000+ km, 33+ hour solo was a different ride on a different day, my longest single indoor effort to date. Both more head game than fitness.
Calm seas, dolphins, and a long quiet swim. Open-water work has stayed central to how I think about endurance.
Interview after running on the frozen Japanese Sea at −30 °C (−22 °F). The cold makes pacing and fueling decisions look different.
The last day of a 42 + 42 + 21 km running stage race. One of the most memorable finishes I’ve had.
One of several welfare initiatives I’ve been involved with over the years. Sport as a vehicle for community and continuity.
Held in the Beijing Olympic Park. Local media called it “Play your way to fitness”, not wrong.
Joint interview on running mechanics with Dr Nicholas Romanov, technique, posture, and the parts of running that scale with experience.
A double-page piece on the cold-spring winter run where participants wore... less than necessary. Strangely effective for community building.
Made it as un-technical as I could without losing the thread. Marathons are easier to film than to explain.
Near the bottomless lake in Shangri-La, promoting local tourism and a scenic 5 km on thin air. ~13,000 ft and a long way from sea-level fueling math.
More coaching projects, documentaries, and adventures available on request, the list keeps growing.
Common questions before applying for coaching.
Yes. I’ve worked with athletes locally in greater Los Angeles and internationally. Day-to-day prescription, feedback, and adjustments work fully remotely; testing days at the Performance Lab or partner facilities pair in when useful.
Yes, from true beginners aiming to finish a first race, to age-groupers chasing championship qualification, to elites aiming for the win. The plan changes; the standard of attention doesn’t.
I’m comfortable across swim, bike, and run mechanics. If the question is “can you coach running only?”, absolutely. Plenty of Boston and UTMB qualifiers in the back-catalog.
Yes, I’m actively building workshops and training camps in Europe, Asia, and the Middle East. Send a note if you have a venue or community in mind.
Send a quick note. Tell me about your sport, your level, your race goals over the next 12–18 months, and the constraints you’re training around. I reply within 1–2 business days.
