How it works
- Pace divides the finish time by the distance, shown as minutes and seconds per kilometre or mile.
- Speed divides the distance by the time in hours.
- Switch units any time; the maths converts underneath.
Good to know
- A 50-minute 10K needs 5:00 per kilometre — train slightly faster in intervals.
- Hills, wind, heat, crowds and going out too fast all cost time on race day.
- Nothing is stored or sent anywhere.

Frequently asked questions
What pace do I need for a goal?
Divide the goal time by the distance: a 50-minute 10K needs 5:00 per kilometre. Train slightly faster in intervals.
How do I convert pace and speed?
Speed is 60 divided by pace in minutes per unit: 5:00 per kilometre equals 12 kilometres per hour.
Why is race pace slower?
Hills, wind, heat, crowds and going out too fast all cost time. Flat, cool and even splits are fastest.
