What this result means
A 10K is 10 kilometres, or 6.214 miles. Enter a target time to get average pace, speed, and even kilometre or mile splits. The distance is locked; you only choose the clock.
Road 10Ks sit between a hard 5K and a half marathon. This page does not scale a 5K into a 10K. For that equivalent, use the race time predictor. For training paces from a 10K result, use the training pace calculator.
A 50:00 10K requires 5:00/km or 8:03/mile. You would pass 5K in 25:00 on even splits. A 42:00 10K is 4:12/km or 6:46/mile — a different session from a 5:00/km 10K, not a rounding of it.
A 60:00 10K is 6:00/km or 9:39/mile. Many first 10Ks live near that hour. The split table still assumes even pace; a conservative first 2 km and a faster last 3 km can still hit 60:00 without matching every row.
Calculation method
Pace is finish time divided by 10 kilometres (or 6.214 miles). Each split is target time multiplied by (split distance ÷ 10 km). Displayed times round to the nearest second.
This is exact arithmetic, not a prediction of how the second 5K will feel. Fatigue is real; the formula does not model it.
A 10K is long enough that even splits are a tactic, not a law. Wind, hills, and drinks stations move the clock. The average pace is still the number you have to average.
Frequently asked questions
What pace is a 50-minute 10K?
5:00 per kilometre, or about 8:03 per mile. Even splits put 5K at 25:00.
What pace is a 42-minute 10K?
4:12 per kilometre, or about 6:46 per mile. Enter 42:00 here to see full splits.
How does a 10K pace compare with 5K pace?
This page does not convert a 5K into a 10K. It only splits a 10K target. Use the race time predictor for equivalent performances.
Is 10K the same as 6.2 miles?
10 kilometres is 6.2137 miles, usually shown as 6.214. Some US road 10Ks are certified in metres, not a round 6.2 miles.
