Half Marathons Found In Stevenage
View all ↓Half Marathons in Stevenage 2026 - 2027
The most comprehensive list of half marathons in and near Stevenage in 2026 - 2027. Find your perfect race!
Stevenage was purpose-built with a network of separated foot and cycle paths that link the whole town, and for half marathon training this means you can cover substantial mileage without dealing with traffic or road crossings. Fairlands Valley Park is the main park destination on the network, with lakeside paths and open ground for the more contained sessions. The Forster Country trail heads out of the town for longer runs on more open ground. Build up with 10K runs in Stevenage before stepping up to the half.
Have a browse through the listings below. Shephalbury Park on the eastern side of town and Town Centre Gardens in the centre are both worth a look for additional flat ground. Marathons in Stevenage are there when you're ready to go further.
