Coaching Approach

How I think about training

Challenge Taiwan 226 km. Crossing the line with my family.

Training that works is built on sports science and honest data, then written for one athlete. Talent and a good day only take you so far. Kona slot, new PR, first triathlon you want to finish in one piece: whichever it is, a precise prescription with a system behind it beats guessing, and it gets there faster.

I have a family and a business to run, so I know exactly what “not enough time” feels like. On weekdays I train in the window after the school drop-off, and two hours is a luxury. When there’s no time to waste on junk work, every session has to earn its place: where the zones came from, why this interval set sits on this day, and how much accumulated fatigue means it’s time to back off. I can explain all of it.

I coach and race at the same time. Around work and family, I’m still setting PRs and still getting on podiums. Everything I figure out doing that becomes your shortcut: the fastest way to get the most out of the training time you actually have.

After years of this, the athletes who go furthest are almost always the ones who find a balance between work, family and their own ambition. So my job is bigger than writing the plan. It’s keeping you improving inside the life you already have, so that when you get to the start line and cross the finish, everything that matters most is still intact.

My goal is to coach a Chinese endurance athlete all the way to the top in my lifetime, onto an Olympic or World Championship podium.

Track Record

Coaching results

Here’s what the science-based approach has produced since 2016.

Record setter: Li Pengcheng
8:17:22Li Pengcheng’s IRONMAN personal best, 2026 IRONMAN Hamburg
8:48:06Li Pengcheng’s third place in M35–39 at Kona 2026, his fourth IRONMAN World Championship podium
3:51:35Li Pengcheng’s 2025 IRONMAN 70.3, the fastest ever by a Chinese man

Li Pengcheng (李鵬程), who I’ve coached for years, keeps moving the bar. At Kona 2019 he went 9:01:29 and became the first Chinese athlete on an IRONMAN World Championship podium, and he’s been back on that podium three times since: Nice 2023, Kona 2024 and Kona 2026.

20+Behind the podiumsMore than 20 athletes have earned IRONMAN World Championship slots, and the count keeps going up.
3BreakthroughsThree athletes under 9:00 at the full distance (226 km), and several under 4:30 at 70.3 (113 km). The individualized system holds up.
100+Athletes with day jobsPlans that fit a real week. The job stays, the family stays, and the full-distance race still gets finished healthy.

Core Expertise

What I specialize in

IRONMAN U Certified Coach

IRONMAN® Certified Coach

IRONMAN and 70.3 are about as demanding as endurance racing gets, and racing away from home adds a whole layer of unknowns. We build the course plan and the power strategy together: how to handle a climate you aren’t used to, what to rehearse in training first, and the exact pacing targets for the bike and the run. That takes the guesswork out of race morning, so all that’s left is execution.

STRYD Running with Power

Running power specialist

I’ve been studying and coaching running power since 2016, and I was one of the first coaches in the Asia-Pacific region to earn STRYD Level 2. The athlete who went 9:01:29 at Kona in 2019 trained with a power meter. He spent his energy well on the day, ran a 3:05 marathon off the bike, and moved from 21st to 5th in his age group: the first Chinese athlete on an IRONMAN World Championship podium.
