Frieth Hilly 10k - Frieth Hilly 5k

The Frieth Hilly 10k and 5k, held annually on October 15th in Henley-on-Thames, Buckinghamshire, offers a challenging yet scenic trail running experience. As an established event, participants can anticipate well-organized races through the picturesque Chiltern Hills. Both distances are renowned for their undulating courses, meaning runners should be prepared for significant elevation changes throughout. The Frieth Hilly events are characterized by their demanding terrain, primarily consisting of woodland trails, muddy sections, and steep ascents and descents. The autumn date in mid-October suggests that participants should expect typical late autumn conditions: potentially damp and muddy underfoot, with cooler temperatures. This race is not for the faint-hearted, offering a true test of stamina and trail-running skill amidst the natural beauty of Buckinghamshire.
