View all races for Jun 2026

P24 The Longest Attended Day is a unique endurance running challenge held at Denbies Wine Estate in Surrey. Participants attempt to complete one mile on the hour, every hour, for 24 consecutive hours, testing consistency, pacing and determination rather than outright speed.

The event uses a flat looped trail route through the wine estate, making it accessible to a wide range of abilities. Between miles, runners can rest, socialise and enjoy the supportive atmosphere while preparing for the next hourly start.

Fully chip timed and supported throughout the challenge, the event combines endurance running with a strong community spirit. Runners who successfully complete all 24 hours earn the distinctive P24 finisher medal, marking the achievement of a memorable and unusual ultra endurance challenge.
