LeCoach: An AI Cycling and Running Coach Built on Intervals.icu

Serious cyclists and runners have long had two options. A human coach gets to know you, answers your questions, and builds training around your life for €150–300 a month, with answers delivered at the weekly check-in. Or apps like TrainerRoad and JOIN that adapt automatically, but you cannot ask them anything: why this workout, why did my week just change, what should I eat before Sunday’s race? The plan adjusts in the background, and you are expected to trust its algorithm.

LeCoach is an AI cycling and running coach built to be the third option: priced like an app, but behaving like a coach. It gets to know you as an athlete, builds training plans around your athletic profile, your goals and available time, watches your training daily, and is there to talk to whenever you want, before the 6 a.m. session, not at next week’s check-in.

Built on Intervals.icu, connected to everything

LeCoach runs on top of Intervals.icu, the free and increasingly popular analytics platform many endurance athletes already use. That single connection does a lot of work. On the way in, LeCoach sees everything you record: rides, runs, power, pace, heart rate, HRV, sleep, weight, whatever device or platform it comes from. On the way out, every workout LeCoach plans for you syncs automatically to Zwift, Garmin, Wahoo, Rouvy, MyWhoosh and more. So this morning’s workout is simply waiting on your head unit or trainer. No exporting files, no copying workouts across apps.

An AI coach you can actually talk to

Most training apps now claim some form of AI. The difference is that for LeCoach, AI is truly the core. The coach has your full history, your plan and your recovery data in front of it, and you use it the way you would use a human coach, except it never stops, it answers at any hour and never bills you for the extra questions.

Some real examples from my own training:

• Workouts that fit the athlete I actually am. I’m a diesel: strong aerobic engine, weak anaerobically. JOIN’s VO2max sessions were always too hard for me, because they were pitched at a percentage of FTP that assumes an average power profile. LeCoach knows my profile from my data, so it starts VO2max work at an intensity I can actually complete, then progresses it week by week to raise my anaerobic ceiling, rather than serving the same canned session I would blow up on.
• Analysis that no human coach has time for. I am training for the Maratona dles Dolomites, an event I also rode in 2023. I asked LeCoach to compare my current build with the months leading up to that 2023 edition. It tells me where I’ve improved, where I’m behind and what is missing in my training. It worked through both periods in detail: training load, power records, recovery signals, intensity distribution, and came back with useful insights and specific sessions to add. A human coach could do that in theory, if you paid for the hours. Neither TrainerRoad nor JOIN can do it at all.
• Chat about everything related to training. A fueling plan for race day. Why does the plan put threshold work where it does? A deep dive analysis of yesterday’s ride. Whether to train through a cold. Because LeCoach has all your context, its ride-and-run analysis digs deeper than most coaches could ever manage. Expect to become a better athlete all around.

Plans that adapt, with you in the loop

Underneath the conversation sits a proper periodized plan, built around your goals, schedule, fitness level and your strengths and weaknesses. And it adapts as your training unfolds, without silently rewriting your week. Each morning, LeCoach reads your recovery (it even has its own recovery score, which in our testing reads your recovery better than Garmin’s Training Readiness) and tells you whether you are ready for today’s session or better served by an alternative. The keyword is tells: one bad HRV reading does not force a rest day. The coach explains what they see, proposes a change, and leaves the decision with you.

After each session, an Execution Score indicates how closely you matched the plan. Every week, a written AI review covers what you did versus what was scheduled and what it means for the week ahead. And the Plan Health Score keeps a running check on the bigger picture, flagging overreaching, poor recovery, or a plan drifting away from its intended focus.

And there’s more

Around the coaching, there is a set of features you will not find together in any other cycling training app. A calendar view puts workouts, activities, and wellness into a single overview. An analytics dashboard tracks metrics such as fitness (CTL), estimated FTP, power profile, and recovery trends. You can ask LeCoach to create a workout on the fly (“a 75-minute over-under session for tomorrow”) or edit any workout yourself in a text-based editor fully compatible with Intervals.icu’s format. And then there’s weight tracking, habit tracking, and more. The sum is more than an AI coach you talk to or an app that hands you workouts: it is everything you need to become a better, more informed athlete.

What athletes say

LeCoach started on the Intervals.icu forum and is still shaped by that community. Suggestions posted there tend to turn into features quickly. The feedback from athletes, unprompted: “game changer”, “LOVING this app”, “by far the best experience out of all the AI coaches”, “it actually listens to my requests, and it makes sense“.

Getting started

One limitation to note: LeCoach requires an Intervals.icu account to be used to its full potential. Intervals.icu is free, and that single account provides LeCoach with your complete health and recovery data, every activity from every device you own, and automatic workout sync across all your platforms. If you already have an account, connecting to LeCoach is a single click; if not, LeCoach guides you through creating one in under a minute. From then on, the link runs both ways on its own. There is a 14-day free trial (no payment needed), so you can try it properly before paying anything.

The bottom line

LeCoach is an AI cycling coach and AI running coach for the self-coached athlete who wants what a human coach actually provides (a plan built around them, daily attention, and someone to ask anything, anytime) at app prices. It connects to Intervals.icu once, sees everything, and talks back. You can try it free at lecoach.app.
