The most comprehensive list of Half Marathons in and near Watford in 2026 - 2027. Find your perfect race!
If you've been putting in miles along the Grand Union Canal towpath or through Cassiobury Park, you'll know that Watford is flatter than most of Hertfordshire, and that makes a difference at the half marathon distance. Thirteen miles on forgiving ground is a different proposition to thirteen miles with hills in the way, and Watford gives you a fair shot at a time you'll actually be pleased with. It's one of the better spots in the region if a PB is what you're after. If you'd rather build up first, 10k runs in Watford are a good place to start.
Have a look and pick one that works with your training. When the half marathon feels comfortable and you want to know what 26.2 feels like, marathons in Watford are the next step up.
