📐 Formula

Pace (min/km) = Time (seconds) ÷ Distance (km) ÷ 60. Speed (km/h) = 3600 ÷ Pace (sec/km). Finish Time = Pace × Distance

Frequently Asked Questions

A comfortable beginner pace is 8–10 minutes per km (13–16 min/mile). For a 5K, that's 40–50 minutes. Focus on finishing without stopping before worrying about pace.

You need to average 5:41 per km (9:09 per mile) to finish a half marathon (21.1 km) in exactly 2 hours. Aim for 5:35/km in training to have a buffer.

Speed (km/h) = 60 ÷ pace (min/km). For example, a 6:00/km pace = 10 km/h. A 5:00/km pace = 12 km/h.
