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.

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.
