The Gorrick 100 mountain bike enduro takes place on Sunday 2nd May in and around SwinleyForest, Bracknell, where the latest Harry Potter instalment is being filmed.
On a loop with a total distance of ten miles, hardcore riders will have the option of completing up to seven laps of the course which spans Swinley, the Surrey Hills and Crowthorne Woods.
For the less masochistic, there’ll be races for 1, 2, 3, 4 and 5 laps leaving throughout the day.
Although pre-booking is recommended via the Gorrick website, on the day race registration opens at 8.00am.
