Predict your race finish time based on your time at any split checkpoint. Enter your split and see your projected finish assuming even pacing throughout the race.

Race Distance
Split Checkpoint

finish = split time × (race ÷ split distance)

(pure linear extrapolation — no fatigue adjustment)
Time at 1KFormat: MM:SS or H:MM:SS
Projected 5K Time

Enter your checkpoint time and the projection lands here. Try:

This projection assumes you hold your checkpoint pace to the line — early splits usually flatter you. For predictions between different race distances, use the Riegel race predictor, which accounts for fatigue.
