About the Oxon 40/20

Oxon 40/20 2021 Anytime Challenge Event

Monday 12th April 2021 to Monday 28th June 2021

This unsupported anytime challenge event is a replacement for the traditional Oxon 40/20 which had been planned for May 1st 2021. Entrants can participate at a time of their choosing between 12th April 2021 and 28th June 2021. The event is entirely unsupported, so there are no refreshments provided and no marshals on the route or providing support in any way.

The event offers the choice of routes

  • 20 mile
  • 32 mile **
  • 40 mile

** The 32-mile route is a shortened version of the 40-mile route; a decision on which distance to complete can be taken at Russell’s water, approximately 26 miles into the walk. The same GPX file will be provided for both routes, see the route description for the point the routes deviate.

The event continues to be in the scenic Chilterns, including Bluebell woods. If the walk is undertaken before mid April the bluebells are unlikely to be fully out.

When choosing the distance to enter entrants should take into account that completing the route unsupported is a harder challenge than doing so as part of a normal supported LDWA event; this is particularly true of the 40-mile event, which includes significant hills, and where completing the distance in daylight hours will be a challenge.

Entries open: TBA.

The main start will be at Stokenchurch Green (GR SU 760 963), an alternative start Cowleaze Wood Car Park, (GR SU 725 956) may be more convenient for parking, Details will be provided in the route description.

Route Descriptions and GPX

The route descriptions and GPX files will be e-mailed to entrants by 12th April or within 3 days of Entry if that is later.
