Running Pace Calculator
Convert between pace, distance, and time. Plus split-time tables for 5k, 10k, half-marathon, and full marathon at your pace.
At this pace, you'd finish:
- 1 km5m 30s
- 5 km27m 30s
- 10 km55m 0s
- Half marathon1h 56m 2s
- Marathon3h 52m 4s
How to use
- 1
Pick what you want to calculate: time, pace, or distance. Fill in the two values you know.
- 2
Pace inputs use minute + second pickers. A 5:30/km pace = 5 minutes, 30 seconds.
- 3
Time inputs split hours + minutes + seconds for long runs.
- 4
Distance is in km or miles — pick the unit below.
- 5
The result includes split times at standard race distances so you can sense-check your effort.
Frequently asked questions
Multiply min/km by 1.60934. So 5:00/km × 1.60934 ≈ 8:03/mile. The calculator handles this automatically when you switch units.
Subjective, but reference points: casual jog ~7:00/km, fit recreational runner 5:00-6:00/km, sub-elite ~4:00/km, elite marathon runners ~3:00/km. World records: marathon ~2:53/km, 5k ~2:30/km. Most people improve from the 7:00 range to the 5:00 range in a year of consistent training.
Whatever your tracker app uses, since most prescribe pace in the matching unit. UAE runners largely use km; UK and US runners use miles. The race distances on the splits table are universal — 5k is 5k everywhere.
The math is exact: split time = pace × split distance. Real-world variation comes from how steady you actually run — going out too fast for the first km is the classic mistake that blows up a marathon. The splits table gives the perfectly-even-pace targets.
Half = 21.0975 km. Full = 42.195 km. They're not round numbers because the marathon distance was standardised in 1908 to match the King's preferred course length (from Windsor Castle to White City stadium). Half is exactly half of that.
