Phoenix: 2359 - The End

Phoenix: 2359 - The End is scheduled for Wednesday 31 December 2025 at Ardingly Activity Centre, Ardingly Reservoir, Haywards Heath, West Sussex. The event is organised by Phoenix Running and Phoenix Running West Sussex. Entry fees listed are £37.95 for affiliated runners and £39.95 for unattached runners. Fancy dress is encouraged. All participants receive a bespoke finisher's medal or giveaway memento. The organiser offers both attended and virtual participation.

Format and distances

The event uses a 5.00 km (3.28 mile) out-and-back lap around the edge of the reservoir on an undulating, off-road, compact trail. Participants may complete as many or as few laps as they wish within a full 7 hour time limit. The minimum distance is 3.1 miles (5 km). Available distance options mentioned include:

  • 5 km
  • 10 km
  • Half marathon
  • Marathon
  • Ultra

The event operates a flexible "rock up and run" start format so participants may start when they arrive, provided they finish within the event time limit. There is an option to also enter the first event of the following year and complete both events back-to-back. UK Athletics distance restrictions apply for participants aged 20 or under; full terms and conditions cover these rules. Visit the organization's website for the most recent information.
