Split Time Calculator

Plan every checkpoint of your race.

How to Use This Tool

  1. Enter total race distance and target time.
  2. Enter number of checkpoints.
  3. Get split times and pace per km.

The Formula

Split Time = (Target Time / Distance) × Split Distance.

Why It Matters

You are running a 10K race wanting to finish in 50 minutes. Splitting the race into 5 checkpoints (every 2K), each segment takes 10:00. At checkpoint 3 (6K), your split should be 30:00. 30 seconds behind means speeding up by ~6 seconds per km.
