Coaching Rooms — live

One room. The whole roster. Live splits.

A coach opens a room; athletes join in seconds with a code or QR. Describe the workout in plain words and AI builds the session — pace groups and per-group targets for the whole roster. Splits, leaderboard, and chat sync live, and keep working in dead spots on the track.

  • Join with a 6-character code or QR — seconds, not a signup drive.

  • AI writes the session with per-group pace targets; the coach edits everything.

  • Live splits with heart rate, realtime leaderboard, room chat.

How it works

Four steps.
Zero wearables.

01
Tell us your goal.
Race distance, target time, starting fitness, weekly availability. Two minutes of onboarding.
02
Generate your plan.
A full periodised season — base, build, taper — generated in seconds and dropped into your calendar.
03
Film yourself. Get scored instantly.
The app reads your form against biomechanical research. Each session stacks into a history of how your mechanics improve.
04
Adaptive periodisation.
The model reads your session data — form scores, completion rate, load — and adjusts intensity and volume for the week ahead. Evidence-based, not guesswork.
