Chiltern 50 Challenge

Take in the beautiful views of the Chiltern rolling hills and to tackle an Ultra!


Part of the Ultra Challenge Series, this will be the last event of the year (which gives you plenty of time to train)! Join either the shorter 25km or tackle the proper 50km. The looped route covers some of the best of the Chilterns countryside. You can walk, jog, or run along historic trails and over rolling hills.

Runners start at 06:00-07:00 and have to finish the course in sub 8 hours. Joggers and walkers depart from either 07:00-08:00 or 08:00-09:00 time slots. The course starts & finishes at the base camp in Henley. There will be celebratory BBQ & entertainment on Saturday night with extensive on-site camping & parking options.

You don't want to miss this! If you haven't already, you know you want to tick off "Complete an Ultra" from your bucketlist. You'll be passing through nature reserves, forests, and hills with great views - it's a route with real variety, and some wonderful scenery - and it's all easily accessible from London.

Check out the event details and sign-up here:

There's three ways of joining - Charity Sponsorship (low reg fee, but lots of fundraising), Charity Mixed Funding (50% off and lower fundraising) and Self Funding (total cost - £129). Yet, there is a "New Year's" discount, but up until the 14th of February, so book your place ASAP!

Let me know if you want to join as I have setup a team - "GoodGym Ultra" :)
