How it works
Pace means the time it takes to cover one kilometre (or mile). Formula: Pace = Total Time ÷ Distance. In the reverse calculation, finish time = pace × distance. Speed and pace are opposites of each other: speed (km/h) = 60 ÷ pace (min/km).
Example 1: 10 km in 50 minutes — pace = 50 ÷ 10 = 5:00 per km, speed = 12 km/h.
Example 2: At a 6:00/km pace, marathon (42.195 km) finish time = 6 × 42.195 ≈ 4 hours 13 minutes.
How to use
- Enter your distance and total time in section 1 to see your pace per km, pace per mile and speed.
- Use section 2: enter a target pace and distance to predict your finish time.
- Check the table to compare finish times for 5K, 10K, half marathon and marathon at your pace.
