Race format and entries
Participants run as many complete laps of the 4.14-mile loop as they can within the 6-hour race window. Runners may stop at any time; an incomplete final lap will not count toward total distance. Solo athletes will move to a shorter final lap for the last hour. Relay teams are two-person teams; teams decide their lap strategy and may alternate laps as they choose, but any lap started must be completed to be counted. The organisers state there are spaces for up to 400 solo runners and 50 two-person relay teams. Early entry fees are listed and change after 31 Dec 2025; a service fee of 4% (minimum 50p) applies to each sign-up. Visit the organization's website for the most recent information.
