Race time calculators for running, cycling, swimming, triathlon and Hyrox

Pick a distance, then type your pace or speed to see your finish time, or type the time you're aiming for to see the pace you need. Each sport works in the units its athletes actually use.

Pacey is an app for iPhone, and it's free right now. It's being tested through Apple's TestFlight and isn't on the App Store yet.

Join the Pacey beta
  1. On your iPhone, install Apple's free TestFlight app from the App Store.

It's a test version, so you may find rough edges: please tell us through the Feedback tab. Places in the beta are limited; if it's full, Apple's page will say so.

Five sports, each done its own way

  • Running

    Pace per kilometre or per mile, with the matching speed. Quick picks from 5K to 50K, including the half and full marathon.

  • Cycling

    Speed in km/h or mph rather than pace, with common ride and time-trial distances for both metric and imperial.

  • Swimming

    Pace per 100 m or per 100 yd, never km/h. Pool distances in metres or yards, plus 1500 m and 3.8 km for open water.

  • Triathlon

    Swim, first transition, bike, second transition and run add up to your finish time. Sprint, Olympic, Half and Full templates, or your own distances.

  • Hyrox

    Eight 1 km runs and the eight stations in race order, with a split per 500 m for the SkiErg and Rowing.

One Metric or Imperial switch covers the whole app, and the calculators work without a signal.
