50% of your personal fundraising target must be raised by the registration deadline stated above – 24th March 2026
We do have a range of additional optional extras designed to make the planning for, and joining your challenge easier. Sign-up to your chosen Challenge first – and you can then book any optional extras later / separately.
You must be 18 or over (on the day of the challenge) if taking on a Full Challenge (~100km) or Three Quarter Challenge (~75km); 16+ and accompanied by an adult if taking on a Half Challenge (~50km ), 14+ and accompanied by an adult if taking on a Quarter Challenge (~25km) or Marathon); for a Half Marathon aged 12+ and accompanied by an adult; and finally 8+ & accompanied by an adult for a 10km/mile Challenge.
Under 18s taking part must be signed up by someone over 18.
You’ll receive a ‘transaction receipt’ (via email) along with a Confirmation Email. This will provide details regarding any next steps, timelines you need to be aware of, and how & where to find all the info / details you’ll need for your Challenge. (NOTE– If you don’t receive that e mail within 12 hours, please check your spam/junk mail folders)
You will receive your Start-time email 4 weeks before the challenge takes place.
You will receive your e-ticket email between 10 and 14 days before the challenge takes place.
(NOTE– If you haven’t received your start-time/e-ticket email within 3 weeks/7 days of the challenge, please check your spam/junk mail folders and let your designated event coordinator know)
If your team are doing Option 2 or 3, you can expect to hear from your charity within 14 days. If you do not hear from them – please contact them directly, and also email us at charity@actionchallenge.com & we will follow up with the charity for you.
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.
