Running Pace Calculator | Pace, Time & Distance

Pace = Time / Distance. For example, finishing a 5K (3.1 miles) in 31 minutes gives a pace of 10:00 per mile. Lower pace numbers mean faster running. This calculator solves for pace, finish time, or distance — enter any two to find the third.

Simple mode handles quick pace/time/distance solves. Race Planning adds race presets (5K, 10K, half, full marathon) and predicted finish time based on current pace. Training mode emphasizes heart rate zones and age-adjusted pace interpretation.

Speed (mph) = 60 / Pace (min/mile). A 10:00 min/mile pace = 6 mph. Speed (km/h) = 60 / Pace (min/km). A 6:00 min/km pace = 10 km/h. This calculator shows both speed and pace automatically.

A common first 5K goal is to finish in 30-40 minutes, which requires a pace of roughly 9:40-12:52 min/mile (6:00-8:00 min/km). Start with a comfortable conversational pace — you should be able to speak in short sentences. Use Race Planning mode and set a 5K finish time target to see the required pace.
