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

The event is a set of road races at Dorney Lake in Eton, Windsor. It offers three distances:

  • 5k
  • 10k
  • Half marathon

The course is on paths around the lake and is described as flat on a closed road section. Organisers recommend road running shoes. The 5k turns at the far end of the lake, the 10k completes a full loop before returning, and the half marathon uses additional sections of the lake; the course may be altered before event day. The route is wheelchair friendly and buggies are permitted.

Timing is electronic with chip timing and results can display each runner’s country flag if added during registration. Results can optionally be sent to mobile phones for an additional cost. Finishers receive a spinning medal and trophies are awarded to winners.

On event day, race packs are collected at the venue. Free parking is available but the road within Dorney Lake may be closed during another event, which could require parking farther away and walking down. Bag storage on site is very limited. Toilets are available; clubhouse and showers are not accessible. Nearby stations include Slough and Windsor & Eton Riverside, with other local stations noted for alternative travel.
