Times assume an even pace. Courses with hills, turns or crowds usually run a little slower than the watch says.
Pacing your half marathon
- Go through 10 km at, or just behind, your goal split. Banking time early is the classic way to slow down late.
- Practise race pace in training: a few kilometres at goal pace inside your long run, a few weeks before.
- Take water early and often, before you feel thirsty.
