Join the team in support of Alzheimer’s Society at our Cirencester basecamp for the start of a 100 km looped route through the heart of the Cotswolds. This stunning challenge welcomes over 2,000 adventurers to test themselves across rolling hills, charming villages, the Cotswold Way, and a mix of footpaths and trails with fabulous views throughout.
You’ll enjoy full support and hospitality all the way – including optional university-style accommodation at basecamp – and with 50 km half and 25 km quarter distance options available, there’s a Cotswolds Challenge for everyone.












Ultra Challenge® events are inclusive & accessible to people of all abilities, fitness levels, and experience. Our team will focus on the Full, Half and Quarter distance options – and you can choose which suits you best. Most will walk – but if you want to jog or even run – that’s fine! The Cotswold Way Ultra Challenge® will be fun, safe, and rewarding – with full support all the way, enabling colleagues to push themselves further, and enjoy a great team day out!

Yes – as long as you are fundraising for the same charity, you can create a team fundraising page on Just Giving (we recommend letting your charity know this is how you will be fundraising together). However, please be advised that the minimum fundraising targets remain per person (not per team), so you will need to reach the combined total fundraising amount on your page for your group.
Follow the link in the fundraising section on this page. Alternatively, follow the link in the confirmation email you receive after your register.
Individual page: When you follow the link, it will have already pre-selected your challenge and your charity. All you need to do is enter your personal details and begin fundraising.
Team page: First, complete the same as above. Once you have created your own page, then link it to your teams Group Page.
Only Applicable to Option 2 & 3
All sponsorship goes direct to the Charity via your individual/group JustGiving page.
At least 50% of the ‘sponsorship target’ MUST be with the Charity 3 weeks prior to the Challenge. At this time the Charity agrees to pay the fee for your place to Ultra Challenge (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 your charity.
The remaining 50%, and any extra, should be with your Charity by 4 weeks after the Challenge.
Speak to your charity directly – they will be able to offer you support and help to reach your fundraising target. Only 50% of the target has to be reached by the registration deadline. You have time after the challenge to keep on fundraising.
If you don’t reach 50% of the target, the charity may decline to pay for some team places. If the charity don’t have the minimum amount fundraised, they risk making a loss on any places they pay for. It’s in their hands!
If this happens, your team will have the option to cover the difference or switch to a different funding option. We will be in touch with you with alternative options.
Please refer to the registration deadline provided on this page, pasted red in the ‘Getting Started’ section.
As a general rule, the registration deadline for corporate teams will be 25 days before the event takes place. Our advice would be to sign up as soon as possible!
