About Kiprun Pacer

Decathlon gives the whole app away, with no subscription tier at all. Plans cover 5K, 10K, half marathon, marathon, and trail running out past 120km. After each session you file a debrief, and the app adjusts your fitness level and the rest of the plan around how it went. Sessions export to Garmin, COROS, Apple, Polar, Suunto, and Fitbit watches.

  • No subscription tier and no in-app purchases.
  • Trail coverage runs past 120km, well into ultra distance.
  • The plan responds to how you say a session felt, not only to the data.
  • Includes guidance on nutrition, hydration, strength, recovery, and mental preparation.
