*SUMMER DEAL* DISCOUNTED REG FEES UNTIL 3 JULY!

Join us on this beautiful looped route covering the best of the Chilterns countryside along historic trails and rolling hills.

The Chiltern 50 is a brilliant way to either end your Ultra Challenge season with a bang, or a great challenge to start your Ultra Challenge journey. Walk, jog or run a 50k, 25k or 10k loop as an individual or a team, with full support and hospitality all the way. With a start & finish at a basecamp in Henley, there’s also a Saturday night celebration BBQ, bar & entertainment, with extensive on-site camping & parking options – there’s a challenge for everyone! 

Be part of the team in 2023 and we’ll support you as you help us pick up the pace to a cure!

Important information from the event organiser

All sponsorship goes directly to the Charity via your online Just Giving page. At least 50% of the sponsorship target should be with the Charity 3 week prior to the Challenge. At this time, the Charity agrees to pay a fee for your place to the Organiser (similar to the Self Funding cost – or half of it for Mixed Funding as you’ve already covered half). Failure to meet the deadline may result in cancellation of your place by the charity. The remaining 50% and any extra, should be with your Charity by 4 weeks after the Challenge.

This event is organised by Action Challenge.

If you have any questions, don’t hesitate to get in touch with the events team events@thebraintumourcharity.org or call 01252 237867.
