Running tools

Simple calculators to prepare your sessions and your races. Your profile (MAS, heart rate) is shared by the tools and stays on your device.

  • Pace chart

    Split times by pace and distance, coloured by your MAS, and your training zones.

  • Race time predictor

    Estimated time over 5 km, 10 km, half and marathon, and the pace to hold for your goal.

  • Interval session

    Target time and splits every 100 or 200 m, total time and distance of the session.
