Start/ Finish Location

Registration, Race Start, Race Finish and Race HQ are at Goring Village Hall, High Street, Goring-on-Thames, Oxfordshire, RG8 9AG.

Route

The race route consists of a single 50 mile loop through the Chiltern Hills. Starting and finishing in the riverside village of Goring On Thames, It begins by heading down the 'hilliest' section of the Thames Path National Trail to Whitchurch, before joining the Chiltern Way to Mapledurham. From there it is a short 4 mile section through to Sonning Common, before runners get in to some of the best climbs, descents, valleys and villages that the Chilterns have to offer. Travelling first through Bix, runners then pay a visit to Stonor Deer Park and at Turville and climb steeply out of the village directly past Cobstone Windmill. It's on and down through rolling countryside from there to the Ibstone check point. Runners then continue on the Chiltern Way to the highest point on the course at Christmas Common (800ft), before a fast descent underneath Watlington Hill, to join the Ridgeway as far as Swyncombe Farm aid station. Runners then take the Chiltern Way extension first east, then west to rejoin the Ridgeway at Nuffield. From there it's Grim's Ditch until the final aid station and the turn for home on one of the fastest sections of the course.

A map of the route and a downloadable GPX file can be found at the bottom of this page. The route has 5600 feet of climb, and 5600 feet of descent.
