Phoenix Running Cambridgeshire - Snailed It

Phoenix Running Cambridgeshire stages a lap-based, timed event at Grafham Water, Marlow Car Park, PE28 0BH. The route is an out-and-back lap of 5.3 km (3.28 miles) on tarmac cycle paths with a short section of gravel. The overall course has minimal elevation gain and loss.

Participants choose how many laps to complete within a six hour time limit. The event offers a range of distance options, completed by running the lap multiple times:

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

The minimum distance recorded is one lap (3.28 miles). A one hour rolling start window is operated so participants may begin within that period. Event timing is used to record finished distances and finishers receive a bespoke Snailed It finisher medal.

Entry fees are listed as £37.95 for affiliated runners and £39.95 for unaffiliated runners. Organiser notes that UK Athletics distance restrictions apply to participants aged 20 or under and that places are limited. The format allows participants to decide on distance during the event by completing as many or as few laps as they prefer. Visit the organization's website for the most recent information.
