Features
- Pace, time and distance: enter any two to get the third, in kilometres or miles, with speed in km/h or mph
- Race time predictor: estimated times from 5K to 50K from one recent result, using the Riegel formula
- Split plans: split tables per kilometre or mile for a goal time, with even, positive or negative splits
- Heart rate zones: five zones from a max heart rate, or the Karvonen method with a resting heart rate
- Spectator timing: the time a runner passes each spot, and when to arrive, even across time zones
- GPX privacy trimming: hide the first and last part of a route before sharing it, nothing uploaded
- Browser extension for Chrome, Edge and Firefox: pace, predict and spectator calculators, no data collected
- Dependency-free libraries in TypeScript (npm) and Python (PyPI) that give the same results, MIT licence
