The calculator is free and always will be. Premium adds the parts that decide how your race day and your recovery actually go.
Then $4.99/month. Cancel any time.
Five things, all built around the session you actually entered.
Race Day Strategy
A plan for the event itself — what to carry, when to take it, and how to handle the last hour when most people fall apart.
Recovery targets
Carbs, protein, fluid and sodium after you finish, with the timeframe for each — because you can't drink two litres in thirty minutes.
The Fuel Timeline
Before, during and after, matched to the food and drink you told us you actually have — not a generic table.
Straight from Strava
Connect Strava and a recovery plan is waiting the moment your ride or run syncs. Nothing to enter.
Automatic plans after every session
Finish a session in the app and your recovery plan appears in History, with a notification. No Strava needed.
The free side isn't a teaser. It's the whole calculator.
