Half Marathons Found In Hemel Hempstead

The most comprehensive list of Half Marathons in and near Hemel Hempstead in 2026 - 2027. Find your perfect race!

Hemel sits on rolling Hertfordshire hills, which gives a half marathon here a different character from the flat canal towns to the south. Gadebridge Park is the obvious training base - a large open space in the middle of town with enough room to get proper sessions in. The Grand Union Canal adds flat miles heading out toward Berkhamsted if you want the contrasting option. Want to build up to it? 10k runs in Hemel Hempstead are a good place to start.

Browse the listings below and pick one that works. It's worth to do some hill sessions before you take on 13.1 in Hemel - the Leverstock Green trails to the north of the park are useful for that if you want to get beyond the main paths. Marathons in Hemel Hempstead are there when you're ready to step up the distance.
