Plan A Route 2025: The course is almost entirely off-road. We would advise trail shoes. In the event of flooding and/or adverse weather conditions, we will use the Plan B route, which is pictured below. The decision will be made a week before, and you will be informed via email which route will be in place on race day.

Children’s Fun Run
The Children’s Fun Run (formerly known as the Bunny Run) course is around the recreation ground – three laps makes one 1km. Fun Runners can run as many laps as they like, and will receive a medal showing the distance that they achieved. The record from 2021 was a whooping 14.1km set by two of the year 3-students from The Treehouse School!
To enter, children must be between 4-12 years old inclusive
