About
An AI coach that actually knows you
LeCoach is an AI cycling and running coach. It gets to know you as an athlete, builds training plans around your profile, your goals and your available time, watches your training every day, and is there to talk to whenever you want. Before the 6 a.m. session, not at next week's check-in.
Why I built it
I'm a Gran Fondo rider in my forties, and for years my FTP didn't move. I tried what every serious self-coached athlete tries. A human coach got to know me, but the answers came once a week and the price added up. TrainerRoad and JOIN were affordable and adapted my plan automatically, but I couldn't ask them anything. Why this workout? Why did my week just change? Their one-size-fits-all sessions never quite fit either.
I'm a diesel: strong aerobic engine, weak anaerobically. JOIN's VO2max workouts were pitched at a percentage of FTP that assumes an average power profile, and I blew up on them every time. The app didn't care.
So I built the coach I wanted.
One that knows my profile from my actual data. Starts VO2max work at an intensity I can complete and progresses it week by week. Answers my questions at any hour, and explains its reasoning instead of silently shuffling my calendar.
Six months after switching to it, I had added 28 watts and was setting power records again. That's my story, not a promise. But it's why LeCoach exists.

The third option
LeCoach sits between a human coach and a training app. Priced like an app, behaves like a coach.
It runs on top of Intervals.icu, the free analytics platform many endurance athletes already use. That single connection means LeCoach sees everything you record, from whatever device or platform you train on, and every workout it plans for you syncs back out automatically.
Your full training life in one place, and a coach that has actually read all of it. Ask it to compare your current build with your preparation for the same event two years ago, ride by ride. Ask for a fueling plan for race day. Ask why the plan puts threshold work where it does, or whether to train through a cold.
One connection, everything visible
Rides, runs, power, pace, heart rate, HRV, sleep, weight.
Syncs to where you train
Zwift, Garmin, Wahoo, Rouvy, MyWhoosh and more.
Cycling and running, side by side
Races, walks, hikes and recovery days all in one calendar.
A coach that has read it all
Every conversation has your full training context attached.
What we believe
A coach advises, it doesn't dictate. A coach explains itself. And a coach should make you a better, more informed athlete, not just a follower of workouts.
Advise, don't dictate
Each morning LeCoach reads your recovery and tells you whether you're ready for today's session or better served by an alternative. One bad HRV reading doesn't force a rest day. The coach explains what it sees, proposes a change, and leaves the decision with you.
How adaptive training works →
Transparency over magic
The Execution Score after each session. The weekly review. The Plan Health Score watching the bigger picture. You should always be able to see why your training looks the way it does, and challenge it when something feels off.
Inside the Plan Health Score →
Make you a better athlete
The calendar, the analytics dashboard, the workout editor, weight and habit tracking. Everything you need to understand your own training, not just follow it. The coach is a partner in the process, not a vending machine for workouts.
