Saturn 7 Hour Time Challenge

The Saturn 7 Hour Time Challenge, known as the Great British Bake Run 2025, takes place in Staines along a scenic stretch of the River Thames. Participants run laps of a mostly flat, well-marked course featuring paved paths and a short grass section, with distances customizable from a minimum of 3km up to ultra distances beyond 50km. The event offers a festive atmosphere with a baking competition, an aid station stocked with sweet and savory snacks including vegan options, and a unique cupcake-shaped finisher medal that doubles as a fridge magnet.

Facilities include toilets, changing rooms, parking, and bag drop, making it a welcoming challenge for runners aged 12 and up. Visit the organization's website for the most recent information.
