Formula
split time = (total time ÷ distance) × split distance
Assumes even pacing — equal time per kilometre (or chosen split length).
Worked example
10 km in 52:00 averages 5:12/km, so each 5 km split ≈ 26:00.
Where this can give the wrong answer
- Hills and tactics make real splits uneven.
- First km often slower in crowds.
- Track vs road distance certification differs slightly.
FAQ
- This tool shows even pace; run second half faster manually.
