Running pace chart
Convert a pace (min/mi) into a speed (mph), or the other way around, and read your estimated finish times for the 5K, 10K, half marathon and marathon straight away. The two fields are linked: change one and the other updates. A full reference chart, from 5:00 to 12:00 per mile, completes the calculator. Prefer kilometers? Switch units in one click.
Finish times assume a perfectly even pace from start to finish, with no hills and no slowdown. Over longer distances (half, marathon), reality is almost always a little slower: treat it as a benchmark, not a race prediction.
How to convert pace, speed and time
Pace (minutes per mile) and speed (miles per hour) describe the same thing in two units. You switch from one to the other with a simple rule, since there are 60 minutes in an hour:
Careful: in these formulas, pace is expressed in decimal minutes. A pace of 8:30 per mile reads as 8 + 30 ÷ 60 = 8.5 min/mi. Once you know your pace, your finish time comes from multiplying it by the distance:
Worked example
At a pace of 8:00 per mile (8 min/mi):
- Speed: 60 ÷ 8 = 7.5 mph.
- 5K (3.107 mi): 8 × 3.107 = 24.9 minutes, or 24:51.
- Half marathon (13.109 mi): 8 × 13.109 = 104.9 minutes, or 1:44:52.
- Marathon (26.219 mi): 8 × 26.219 = 209.8 minutes, or 3:29:45.
These times assume a perfectly steady pace. Out on the course, hills, wind and fatigue almost always open a gap, especially over the half and the full marathon: use them to set your pace, not as a promise of a finish time.

Frequently asked questions
How do I convert pace to speed (and back)?
Both express the same thing in two units. To go from a speed in mph to a pace in minutes per mile: pace (min/mi) = 60 ÷ speed (mph). And the other way: speed (mph) = 60 ÷ pace (min/mi), with the pace converted to decimal minutes. Example: 7.5 mph gives 60 ÷ 7.5 = 8 minutes per mile, a pace of 8:00/mi.
How do I convert a mm:ss pace into decimal minutes?
Keep the minutes as they are and divide the seconds by 60. A pace of 7:30 per mile equals 7 + 30 ÷ 60 = 7.5 minutes per mile. That decimal value is the one used in the formulas: speed = 60 ÷ 7.5 = 8 mph.
How do I estimate my finish time from my pace?
Multiply your pace (in minutes per mile) by the distance in miles to get the time in minutes. Example: at 8:00/mi over a 10K (6.214 mi), time = 8 × 6.214 = 49.7 minutes, about 49:43. For the half (13.1 mi) and the marathon (26.2 mi), the math is the same with the right distance.
Are these finish times a reliable prediction?
They are theoretical times at a perfectly even pace, with no hills and no fatigue. For a 5K or 10K they stay realistic; over the half and the marathon, reality is almost always a little slower, because nobody holds the exact same pace from the first mile to the last. For a real race prediction that accounts for slowing down over time, use a model-based predictor (such as VDOT).
Why does the chart stop at 5:00 and 12:00 per mile?
It’s the range that covers the vast majority of recreational and experienced runners, from close-to-PR pace to a very relaxed easy run. 5:00 per mile (12 mph) is already very fast over short distances, and 12:00 per mile (5 mph) matches an easy jog or a comeback run. The calculator above accepts any value.
