Half Marathons in Guildford 2026 - 2027

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

The North Downs Way runs through the Surrey Hills on Guildford's doorstep, which makes the town an excellent half marathon training base. The hills are steep and the ground is mostly off-road; a long run out to Pewley Down will make you work harder than most road sessions do. The River Wey towpath and Shalford Water Meadows are the flat alternatives, good for the steady, longer efforts in the bigger mileage weeks. Build up with 10K runs in Guildford to get a feel for what the distance involves.

Have a browse through the listings below. Stoke Park is the most central training option, with flatter paths that work well for intervals or tempo runs when you want to stay on the flat. Marathons in Guildford are worth a look when you're ready to go further than 13.1.
