P24 - The Longest Attended Day

P24 - The Longest Attended Day takes place at Denbies Wines Estate, London Road, Dorking, Surrey, on the summer solstice weekend of 20-21 June 2026. The concept is simple: run 1 mile on the hour for 24 hours on a flat-ish, off-road 1-mile loop through the estate. Attended participants benefit from full chip timing and a distinctive 12mm-thick, half-kilo finisher’s medal for completing all 24 hours.

On-site camping is available for tents, plus access to toilets and daytime cafe service with hot foods and drinks. A co-ordinated Virtual edition runs in parallel (V-Live) for both attended and virtual runners. Attendance is limited. Visit the organization's website for the most recent information.
