How to pace a half marathon
The half marathon is 13.1 miles (21.0975 km). The best strategy is an even pace or a slight negative split: run the first half a touch slower and pick it up from around mile 9. Choose a negative split under “Race strategy” above to see matching splits.
- GPS watch: your watch will often show 0.1–0.25 miles more at the finish because nobody runs the perfect line. Plan a few seconds faster than the math says – or go by the mile markers.
- Fueling: for races over 90 minutes, water and carbs on the way help. Practice it in training.
- Pace band: with the split calculator you can print a compact pace band – and see at every mile marker whether you're on plan.
- Heat: if it's warm on race day, plan a slower pace. The heat pace calculator shows how much.
