Our 155-mile loop, which starts in London, offers a variety of options to challenge all levels of fitness and expertise.
Those who relish multi-day rides and would like to split the distance across an action-packed weekend can ride 82 miles on the Saturday and then 72 on the Sunday. You'll be able to enjoy our fantastic Basecamp which offers camping facilities, hot showers, bars, food and live music.
Want something extra challenging? Enter our ULTRA and attempt all 155 miles in one go. This is the equivalent of cycling Tower Bridge to Cardiff Bay!
