Race Pace Calculator
Calculate your race pace or target finish time
Frequently Asked Questions
Pace per mile (or km) = total time ÷ distance. For example, finishing a 5K (3.10686 miles) in 25:00 gives a pace of 25:00 ÷ 3.10686 ≈ 8:03 per mile.
Finish time = goal pace × distance. If you want an 8:00/mile pace for a 10K (6.21371 miles), your target finish time is 8:00 × 6.21371 ≈ 49:43.
Common preset race distances (5K, 10K, half marathon, marathon) plus a custom distance option in miles or kilometers.
No — this is a straightforward pace/time/distance conversion. Real-world race performance varies with course difficulty, weather, and pacing strategy, which this calculator doesn't model.
It shows your projected cumulative elapsed time at each mile marker, assuming a steady, even pace throughout the race — useful for checking your watch against a pacing plan during the race itself.
