The Welwyn 10K will take place at 9:30 am on Sunday 21st June 2026. The entire route is set within Panshanger Park, located between Hertford and Welwyn in Hertfordshire.

The event is organised by Garden City Runners in partnership with Welwyn Festival Week, and proudly supported by our sponsors Rise Gym, Tarmac and HRJ Foreman Laws.

This fully signed course is entirely off-road, following a mix of tracks and trails. The route is scenic and best described as undulating, offering a rewarding challenge for runners of all abilities. While paths will be closed to vehicles, please remain mindful of other park users, including horse riders, cyclists, anglers, pedestrians and emergency vehicles.

There will be marshals stationed throughout the course, along with refreshment points and first aid support. You don’t need to be a fast runner to take part, but participants should be medically fit to complete a 10K distance.

This brand-new route offers a unique opportunity to run a measured and fully chip-timed 10K in a stunning setting.
