The All Nations 5k, 10k and Half Marathon Run

The event offers three distances at Dorney Lake in Eton, Windsor: a 5 km, a 10 km, and a half marathon.

The course uses the lake perimeter and adjacent paths. The 5k turns at the far end of the lake, the 10k completes a full loop before returning, and the half marathon includes additional sections around Dorney Lake. The surface is path; road running shoes are recommended. The course is described as flat and is run on closed roads, and it may be altered up to event day. Buggies are allowed and the route is stated to be wheelchair friendly.

Timing and event services include electronic chip timing, race packs collected on the morning of the event, limited bag storage, onsite toilets but no clubhouse showers, and free parking. Results can display a competitor country flag if entered during registration, and there is an optional text result service for a supplementary cost. Finishers receive a spinning medal and trophies are awarded to winners. Cut off times are typically two hours for 5k and 10k and three hours for the half marathon.

Entry and entry change information is managed through competitor profiles. The event operator’s refund policy states a 60 percent refund is available for cancellations at least 14 days before the event and that refunds are not offered within 14 days of the event.
