If you’ve set your sights on a half-marathon, you should be proud that you’re prioritizing your fitness and challenging yourself. If you’ve already completed one in the past, that’s also something to be proud of. A half-marathon is 13.1 miles or 21.1 kilometers, which is half of the distance of a full marathon. It’s more manageable than a full marathon, but still presents a challenge, especially if you’re working on your personal best. It’s also an excellent way to work your way up to the full marathon or an Ironman.
If you’re wondering, here’s the data on the average half-marathon finishing times. No matter your finishing time, you can always work on improving your running performance, speed, and endurance over time. Crossing that finish line is another fitness goal ticked off your list of accomplishments.

- Out of the 3,000 Brits surveyed, 11% have already finished a half-marathon or are actively training for one.
- One out of five runners doesn’t time their runs, showing that not everyone cares about their speed or tracking it.

Half-marathon world record
