Sport
Running paces, race-time equivalents, splits and training zones. For running with your head as well as your legs.
Running
3 tools- Running pace calculator Give me any two of them and I give you the third, plus the split table to take to the race.
- Your equivalent time at another distance From one recent result we estimate what you could do at any other distance. And we tell you when not to trust it.
- Splits for your race Your target time shared out kilometre by kilometre. With the option to plan a negative split, which is how the good races get run.
Pace and effort
2 tools- Heart rate training zones Your five training zones in beats per minute, and what each one is for. With the heart-rate-reserve method if you have your resting figure.
- Swimming pace calculator Your pace per 100 metres, which is how swimming is measured, plus your time per length and what you would do over other distances.
