Frequently asked questions
How long is a Half marathon in miles and kilometers?
A Half marathon is 21.0975 kilometers, which is about 13.11 miles.
How do I calculate my Half marathon 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.
