Surrey - P12 - The Longest Attended Day

The event on Saturday 19 June 2027 stages a P12 format at Denbies Wine Estate in Dorking, Surrey. Participants run 1 mile on the hour, every hour, for 12 consecutive hours on an off road trail that passes through the wine estate. A one-mile route will be used and the course is described as as flat-ish as possible.

The event uses full chip timing and awards a 12 mm thick P12 finisher's medal to those who complete all 12 hours. Attended entrants have access to on-site camping for tents only; mobile homes and campers are not permitted. Between runs there is space for sitting on site and 24-hour access to toilet facilities. During daytime hours the on-site cafe provides hot food from an outdoor serving hatch, including teas, coffees, drinks, bacon rolls, sausage rolls and vegetarian and vegan options.

A simultaneous virtual option runs over the same time period so virtual and attended participants take part in a coordinated V-Live event. Places for the attended event are strictly limited. Distance restrictions based on UK Athletics rules apply to participants aged 20 or under; full terms and conditions govern eligibility and entry. Visit the organization's website for the most recent information.
