Windsor 50 Ultra Challenge

Windsor 50 is a looped trail event based at Windsor Racecourse on Saturday 18 April 2026. Routes run through Windsor Great Park, past the Castle, to Runnymede and along the Thames Path, taking in surrounding countryside. Around 1,500 participants head out from the basecamp.

Participants may walk, jog, or run, and enter as individuals or teams. Options listed for the event include:

• 50 km loop
• 25 km historic loop
• 10 km loop

The event provides marquee rest stops approximately every 12.5 km, with larger rest stops about every 25 km. Rest-stop facilities include catering, seating, changing rooms, medical and massage teams, podiatrists, and self-help supplies for blisters and taping. A timing system scans participants at rest stops and GPS tracking is available through the event app; the route is signed with pink arrows and glow-sticks for night sections.

Catering includes snacks and drinks at the regular stops, a picnic at 25 km for 50 km entrants, energy drinks, dietary options, and a hot meal for 50 km finishers (picnic for 25 km and 10 km). Finishers receive a medal, a T-shirt, a glass of fizz, and a downloadable certificate. The event offers shuttle buses, transfers to local stations, parking for supporters, camping at basecamp, a bar, and bookable transport extras. Corporate team entries and optional hospitality packages are available; over 400 company teams took part in 2025. Visit the organization's website for the most recent information.
