The Westonbirt 10K is returning on Wednesday 29 April 2026, 6:00pm!
The National Arboretum is the perfect location for sporting events, and runners will be able to take in the world-renowned tree collection at one of its most beautiful times of year, with spring blooms and flowering trees providing the backdrop to this unique 10K.
Perfect for those looking for a challenge in the new year, or veteran runners looking to achieve a new personal best, the course takes participants through the picturesque avenues of the Old Arboretum and into the peaceful tranquillity of the ancient Silk Wood, on largely flat terrain and hard paths.
All those taking part in the run will be able to make a big difference to their fitness and wellbeing, as well as to the nation’s heritage and environment. Money raised from the 10K goes back into supporting the nation’s woods and forests, and protecting these beautiful places for future generations.
With a route that takes you past champion trees and some of the rarest species in the world, Westonbirt 10K certainly isn't your average run!
Get your trainers on and run for the trees!
Earlier start time & run waves
To help manage the flow of runners on the trails, we’re introducing race waves. When registering, runners will have selected a wave based on their estimated 10K finish time. Each wave will start at 5-minute intervals, with wave numbers indicating the order of start times.
Run wave start times:
- Wave 1 – 18:00. Estimated 10k finish <45 mins
- Wave 2 – 18:05. Estimated 10k finish 45min-1 hour
- Wave 3 – 18:10. Estimated 10k finish 1 hour – 1hour 15 mins
- Wave 4 – 18:15. Estimated 10k finish > 1 hour 15 mins
Cup-free event
As part of our commitment to reducing environmental impact and supporting the forest, this year’s event will be cup-free. Single-use cups will not be provided at the water stations. We encourage all runners to bring a reusable running cup, bottle, or hydration system to refill at designated water stations. If you don’t already have one, a limited number of collapsible reusable cups will be available to purchase on the day at the 'Friends of Westonbirt' Tent.
