The Smurf Run - Saturn Running

Saturn Running stages the Smurf Run at The Last Hop, Thames Edge Court in Staines. The event is licensed by the Trail Running Association and held under UK Athletics rules. Club members of UK Athletics affiliated clubs receive a £2.00 discount on entry.

This is a 7 hour Time Challenge that lets participants choose how many laps to complete. The minimum recorded distance for a finisher is 3 km. A full lap is roughly 7 km (about 4.37 miles) though the loop may be adjusted to a shorter circuit depending on course conditions. Turn points at 3 km and 5 km are marked within the lap.

Distances offered include:

  • 3 km
  • 5 km
  • 10 km
  • Half Marathon (3 laps)
  • Marathon (6 laps)
  • 50 km
  • Ultra (7 laps or more)
  • Time Challenge (7 hour)

The course runs along a stretch of the River Thames and is fully signed. About 60% is on a paved path or tarmac, with the remainder on grass and light trail that can become muddy. Road shoes are suitable year-round; trail shoes may help on soft sections.

Finishers who complete at least 3 km receive a themed medal. Distance pins are awarded for half-marathon distance and above and are attached to the medal ribbon. All finishers receive a goody bag, with a vegan option available.

Aid and drinks tables are located at the start/finish of each lap with savoury, sweet, fruit, cheese and vegan items. Toilets are available at The Last Hop; there are no dedicated changing rooms or showers. Parking is available at Bridge Street Car Park, Staines TW18 4TP. Final instructions are sent by email in the week before the event. Number pick up takes place on race day at registration. A bag drop area is provided but is not secure. Headphones are allowed and participants should be considerate of other path users. Visit the organization's website for the most recent information.
