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 THE REVEAL Watch your predicted time tick down from today's fitness to your 12-week forecast. Ambitious, but honest. PACECAST PRO • Week-by-week target splits for the full 12 weeks • Forecasts for every distance — 5K, 10K, half marathon, and marathon • What-if scenarios: see how adding weekly mileage changes your finish time • Strava sync: your forecast keeps itself current from your real training • Apple Health auto-refresh keeps your baseline current BUILT FOR RUNNERS • Works in miles or kilometers • A Monday morning notification that tells you what last week actually bought you • Sign in with Apple or Google and your forecasts follow you • A dark, focused design where the numbers are the star Free to try: complete onboarding and get your full forecast and final predicted time at no cost. Upgrade to Pacecast Pro to unlock the weekly curve, every distance, what-if scenarios, and automatic updates. Pacecast Pro is an auto-renewing subscription ($59.99/year or $12.99/week). Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period.

  • This app hasn’t received enough ratings or reviews to display an overview.

Small fixes and polish: • Buttons and text at the bottom of the screen now sit clear of the home indicator. • The "Powered by Strava" badge is now sized correctly. Your forecast, your plan and your data are unchanged.
