Race Split Calculator
Enter your race distance and goal time, then choose a pacing strategy to get a kilometre-by-kilometre split table you can use on race day.
How to use
- Choose your race distance.
- Enter your goal time.
- Choose even, negative or positive splits and read the table.
Note
Negative and positive strategies are modelled with the second half run 2 percent faster or slower than the first half, solved so the splits still add up exactly to your goal time. Real courses, weather and crowds change pacing. Estimate only — not medical advice.
