Let’s make 2026 the year the dental industry joins together to really make a difference. Sign up for Dentistry’s BIG Community Challenge and support Dentaid The Dental Charity as it marks 30 years of changing lives through dental care.
Test your grit and determination by taking on the UK’s original 100km Ultra Challenge on Saturday 23rd and Sunday 24th May 2026. You can tackle the full 100km route, or choose a one-day marathon distance challenge (42km) across the beautiful South Downs, both with a suggested fundraising target of £500.
Alternatively, opt for a 25km loop starting and finishing at Brighton Racecourse with a £300 fundraising target. Each challenge can be taken at your own pace — run, walk or stroll — with plenty of support along the way, and every step you take will help support Dentaid’s vital work.
Dentistry’s Big Community challenge is the ideal networking opportunity, as the event will bring together dental professionals, dental groups and suppliers to the industry. It will be the perfect occasion to forge new connections – which will no doubt be further cemented at the post walk BIG celebration after you cross the finish line!
All the money you raise will help Dentaid provide life-changing dental care for the most vulnerable people in our communities including those experiencing homelessness, harm, poverty and abuse.
Can’t wait for you to join us!

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!
CANCEL YOUR PLACE BEFORE THE REGISTRATION DEADLINE.
If you have already signed up, but then you need to cancel your place – get in touch with your team coordinator immediately. We also recommend getting in touch with us at – corporate@ultrachallenge.com – let us know your team name, event and distance. We can assist you in cancelling your place.
If you wish to cancel your place, but the deadline has passed, you/your company will not receive a refund.
