to help you finish safely. Ideal for achieving a personal best, Dorney Lake in Buckinghamshire provides a flat course for runners and rowers alike. With 94% of participants surveyed achieving a PB in 2021, the Marathon @ Dorney Lake rightfully has the reputation of allowing visitors to push their own limits. Complemented by the grounds, which offer the perfect backdrop, the course also has a maximum time restriction of 7 hours. Once this has expired, the marshals and time keepers onsite will be unable to ensure a safe finish.
