Mince Pi Run - races of 2 decimal places

Mince Pi Run is a lap based running event at Shalford Park, Guildford GU48AA on 13 December 2026. Distances are set around the value of Pi and include multiple options for adults and children. Entry is limited to 200 places and the event status is open.

Available race options include:

  • 3.14 miles up to 31.4 miles (1 to 10 laps)
  • Pi marathon option
  • 1 mile fun run shaped as the Pi symbol for younger children

Junior participation rules are specified by age: 8 to 11 years may run one lap, 12 to 14 years up to two laps, and 15 year olds up to four laps. Children under 12 must be accompanied by an adult at all times. Children aged 12 to 15 must have an adult at the start and finish or may be accompanied.

Most of the course is off road and runs along the water's edge. Some sections have eroded paths and require extra care. Alternative courses may be used if conditions dictate. Race numbers are collected on race morning and competitors must wear their number on the front so laps and times can be recorded. Results will be published online as soon as possible after the event, with an aim to post within 24 hours.

Prices are tiered by date: until 31 March 2026 the fee is £20.36, and until 10 December 2026 the fee is £23.50. Various public car parks are within walking distance; the local Millbrook car park GU1 3XL is about half a mile from race headquarters.
