A 50K (ultra) is 50 km (about 31.07 miles). The chart above turns a range of paces into 50K (ultra) finish times in both miles and kilometers, so you can see at a glance what each pace is worth over the distance.
Working toward a specific goal time instead? Open the full pace calculator, enter your target finish, and read off the exact pace per mile and per kilometer — then use the splits section to map the time you should hit at each marker. To set a realistic goal from a race you've already run, try the race-time predictor.
Frequently asked questions
How long is a 50K (ultra) in miles and kilometers?
A 50K (ultra) is 50 kilometers, which is about 31.07 miles.
How do I calculate my 50K (ultra) pace?
Divide your finish time by the distance. The chart above does this for you across a range of paces; for an exact figure from your own goal time, use the full calculator on the home page.
Is pace different in miles versus kilometers?
It's the same effort, just spread over a different distance. Your per-kilometer pace is a smaller number than your per-mile pace because a kilometer is shorter than a mile. The chart shows both side by side.
