North Downs 50 Ultra Challenge 2024

We’re heading to the North Downs with a fabulous challenge setting out from our Guildford basecamp. Choose your distance, and walk, jog or run the full looped 50km route, a 25km half challenge, or even the Guildford 10km. Take in some of the best of the Surrey hills, the North Downs Way, and the surrounding countryside. A route with real variety and some wonderful scenery & views – and easily accessible from London – there’s a North Downs 50 Challenge for everyone!

Important information from the event organiser

All sponsorship goes directly to the Charity via your online fundraising 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.
