RacePace is a small calculator which helps runners work out distance, time and pace in a flash.

Enter any two of the three values, and RacePace solves the third instantly, showing your speed alongside. It also gives even-pace splits for every kilometre or mile, a full metric and imperial converter, and unlimited saved favourites, all for free with no limits on the core tools.

For runners who want more than a quick number, RacePace Premium adds a split strategy planner, a race time predictor based on a proven endurance model, personal heart-rate training zones, and printable pace bands for race day.

No accounts, no analytics and no tracking. Everything stays on your device, and nothing is ever uploaded or shared.
