ACHILLES.FIT^™

How It Works

What you get today

Everything below is live right now. What isn't, is listed underneath.

• >

  AI training plans

  Multi-week running, strength, cycling, swimming and triathlon blocks built around your schedule, goals and current fitness.

• >

  AI coach, in chat

  Ask for a change, log a session in plain English, or ask why a workout is in your week. It answers with your actual training in front of it.

• >

  Workout logging

  Type "5 mile easy run" or "3x10 squats at 185". Running, strength, cycling, swimming and daily habits.

• >

  GPS run recording

  Record a run from your phone browser - distance, pace, splits, elevation and your route, drawn and saved with the workout.

  Keep the screen on while you run; a browser cannot track GPS in the background.

• >

  Analysis and records

  Personal bests, race-time predictions, recent form, aerobic efficiency, year-on-year mileage, streaks and an activity heatmap.

• >

  Strava import

  Connect Strava and your history comes across, deduplicated against anything you have already logged.

  Limited to our first few athletes while Strava reviews the app, and Strava activities are kept out of the AI coach - their API terms do not permit it.

• >

  Google Calendar sync

  Push your whole training block into the calendar you already look at.

• >

  Reminders and offline logging

  Web push reminders at your local training hour, and workouts logged with no signal that upload when you are back.

• >

  Export and delete

  Everything you have, as JSON or CSV, whenever you want it - and a real delete that takes your third-party tokens with it.

Not yet

Built or in progress, but not something you can use today. We'd rather say so here than have you find out after signing up.

• iOS app and Apple Watch

  Soon

  A native app with a Watch companion, background GPS, and Apple Health sync so your Watch workouts land here automatically.

  Written and not yet released. Apple Health can only be read on the device, so Apple Watch data will always arrive through the app rather than the website.

• Garmin, Whoop, Oura and COROS sync

  Soon

  Activity import plus sleep, HRV and recovery from the wearables that publish it.

  Built and waiting on the vendors rather than on us. COROS approval is pending; Garmin has closed its developer intake entirely, so nobody can give you a date for that one.

• Community features

  Soon

  Challenges, clubs and verified results on top of the leaderboard.

  The leaderboard is live today and is opt-in, ranked, and on the honour system.

Achilles is one of three products we build and run ourselves. The other two take the same approach - an AI coach that adapts to what you actually do - to a different craft.
