3 stages per character. Train consistently, and yours will evolve.
Your character is your pack.
The Arena brings together runners who actually train and who cheer each other on. Everyone follows their own plan, nobody is ranked, and the community moves forward on a map that unveils itself.
And our ambition does not stop at running.
Current season: the Ekiden Road, seven stages across a Japan of legend.
Explore the expedition
Most apps track numbers. Leo asks how your legs felt, how you slept, if that knee is still tight. He turns sensations into data — and data into decisions you can trust.
He monitors your training load week by week and speaks up before the breakdown does — not with jargon, but with "take tomorrow off."
Built on 250+ peer-reviewed papers — periodization, biomechanics, nutrition, physiology, altitude. Leo doesn't recite research: he applies it to your training. He remembers that your left calf acts up after heavy weeks, that you race better with a 3-day taper. A coach who reads the science and knows you.

I tell him how I actually feel, and the plan adjusts. No more guilt when I skip a session: Leo rebuilds the week around it.

Leo spotted that my Thursdays were always flat and moved my hard sessions around. Everything clicked in the final block. Smashed my PB in Paris.

The climbing work was calibrated to my real Strava ascents, not generic hill repeats. On race day it felt like a course I already knew.

A coach who talks to me, remembers my knee and my work schedule. It's the first build-up where I don't feel alone with the plan.

I built Coach Leo for my own build-up. For months, every time the plan got something wrong, I fixed the app rather than the session. It was my first ultra: 70 km, 5,600 m of climbing, and it went exactly as it should.

Coach Leo
7 days freeBefore the card: create your account, connect your watch or Strava, talk to Leo, and get your plan skeleton.
Nothing is charged before day seven. Cancel in one tap.
See all plansChatGPT gives you a generic plan based on a single conversation. Leo syncs with Strava, tracks your training load week after week, remembers your training history, monitors your shoe mileage, and adapts your plan based on how you actually feel — not just what you typed once.
You create your account, connect your watch or Strava, talk through your goal with Leo, and get your plan skeleton. Opening the full plan and the weekly coaching takes a subscription, and its first seven days are free.
Yes — Coach Leo is available on the App Store and Google Play. Leo also works in your browser, on Telegram, and syncs with your watch, so you get the same coach everywhere.
Leo works with ChatGPT, Claude, Mistral, and any MCP-compatible tool. You can also use the iOS and Android apps, chat with him on Telegram, or use the web app.
You connect Strava so Leo can sync your runs (read-only — he never posts or modifies anything). This is how he sees your pace, heart rate, elevation, and training patterns. Suunto sync is also available.
You save your card and get the full coaching for seven days. Nothing is charged before day seven, so if you cancel first, you pay nothing. Cancelling takes one tap from your dashboard. If your subscription starts without free days, you get a full refund within 14 days, no questions asked.
Your data is encrypted, never sold, and never shared. Leo reads your training data (Strava and Suunto) only to coach you — nothing else.
We're building pack-based challenges, weekly competitions between packs, and a progression system tied to your real training. Your character determines your pack — early members will be the first in.
