Running Pace Calculator

Enter how far you ran and how long it took to get your pace (per mile and per kilometre), your speed, and projected finish times for a 5K, 10K, half and full marathon at that pace. Great for planning training runs and race goals. Updates as you type.

How pace works

Pace is time per unit of distance — minutes per mile or per kilometre. It's the number runners use because it's easy to hold during a run: if your goal is a sub-25-minute 5K, you need to keep under 5:00 per km. Speed (mph or km/h) is the same information the other way round — distance per hour.
