Chiltern Wonderland 50

The Chiltern Wonderland 50 is a single 50 miles (81 km) loop through the Chiltern Hills, starting and finishing at Goring Village Hall in Goring-on-Thames, Oxfordshire. The route totals 5600 ft (1700 m) of climb and descent and runs on approximately 80% trail and 20% road. The course is fully marked and no navigation is required.

The event is held under a UK Athletics Permit through the TRA and limits the field to 250 starters. Runners must finish within a 13 hour time limit; additional cut offs apply at aid stations. Five well stocked aid stations serve the course with provisions for vegetarian, vegan and gluten free needs, offering drinks, gels, snacks, fruit and sandwiches. Hot food and drink, including vegetarian and vegan options, are provided at the finish.

Medical support is provided throughout the race with a static first aid team at the finish and at least one roving medical team on course; remote sections may delay response times. Pacers and crew are not permitted; supporters are allowed only at specified locations. Entrants must meet a qualification standard of having completed at least a marathon within that event’s cut off between 1 January 2022 and race day. Entry fee is listed at £118 or £120 for unattached runners. A map and downloadable GPX file are provided for the route. Visit the organization's website for the most recent information.
