It's a 5km (3 mile) obstacle course that circumnavigates the racecourse. The course includes a series of obstacles and 'colour stations' to add to the challenge. Scattered around the course to keep you going are a series of music stations. We took part last year and we all enjoyed it so much that we decided to do it again this year.
Below are a series of photos and a video that we took at last year's event. 👇
