Pacecast: Race Time Calculator

Pacecast is a race time calculator that doesn't stop at one number.

Enter one recent run — or let Apple Health do it for you — and see the time you'd run today, the time you'll run 12 weeks from now, and the week-by-week plan that gets you there.

Connect Strava (Pro) or Apple Health, and Pacecast updates your forecast on its own. It reads your real runs and recalculates your predicted time — no spreadsheets, no re-entering workouts, your number just keeps getting sharper as you train.

YOUR FORECAST, FROM REAL DATA
• Start from a recent race or a hard training run
• Or connect Apple Health and use your real mileage automatically
• Built on a proven race-prediction model with a realistic weekly-gains curve — estimates, not guarantees
• See exactly which run your forecast is built on — and swap it if we picked the wrong workout
