The ‘ULTRA MARCH’ option is for WALKERS who want to hit a sub 24 hour pace (for 100km) or a sub 12 hour pace (for 50km) with a group of like minded challengers. You can opt in to this format & start time (on the Registration Form).

Everyone has to register as we require personal details & declarations. Within the form you can choose to ‘Create’ or ‘Join’ a Team. Teams can be of any size, members can opt for the same or different funding options, charities, or distances.
- Create a Team – you become the Team Captain. You need a Team Name, and a Password for others to join. Then invite friends & family to join you!
- Others join the Team as they register, by searching for the Team Name & using the Password
- Team Start Time – is as per selected by the Team Captain
You need to select a charity to support if you’re fundraising. 3 categories of Charities are involved.
- Official Partners – Long term Series & Challenge partner charities. With the ‘Charity Sponsorship’ option – it’s 50% OFF the normal Reg Fee.
- Associate Partners – 50 or so charities promoting the Series, and it’s 25% OFF normal Reg Fees for the Charity Sponsorship option.
- Listed Charities – 500 or so other charities involved – and the ‘normal‘ Reg Fee applies.
Be careful to tick the right box, or correct selection from the charity drop down list. Your confirmation email details how to set up an online JustGiving page for sponsorship donations (must be done within 48 hours)
All sponsorship goes direct to the Charity via your JustGiving page.
At least 50% of the ‘sponsorship target’ should be with the Charity 3 weeks 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 your charity.
The remaining 50%, and any extra, should be with your Charity by 4 weeks after the Challenge.
Multi Deals are the Best value if you’re up for a 3 or more challenges in 2025 – and plan to ‘Self Fund’.
For those aged 21 or under there’s a ‘special deal’ to help families & groups of young friends to get active & involved.

A Multi Deal allows you to save up to 25% if you plan to enter 3 or more events over the year on a Self Fund basis – and always represent our best deal!
Once you have decided how many events you’d like to enter, visit the ‘Multi Deal’ page on the website – or follow the link HERE>>
On the registration page, you must select all of the events you’d like to enter (and specify the distance) – once you’ve have completed your order, you will need to wait until you have received your multi-deal discount code from the team before you will be able to sign up individually for your events. Placing your order does not constitutes entry to the individual events.
When you are attending the events, please ensure you bring ID to collect your event pack so that we can ensure only the original purchaser is participating.
More information on multi-deals is available HERE>>>
If you have already signed up to a Challenge(s) or a multi-deal and now want to take part in another challenge – please complete our application from HERE>>>
All charity sponsorship and mixed funding places close 4 weeks before each challenge, so that you have enough time to fundraise and reach your target. Self funding places close for online registration on the Tuesday before each challenge.
A discount is available if you have previously taken part as a self funding participant. Please check for availability.
Please keep an eye out for your discount which will be sent to you via email!
Whilst you are signing up and registering for your challenge – in the TEAM INFO section (towards the end of the registration questions), you will be asked if you would like to ‘Join a team’ or ‘Create a team’.
If selecting to create a team, you will be asked to create a Team Name and Password. Subsequent team members can then register and select to join your team, and will need to provide the team password in order to join it.
We ensure that registered teams are assigned the same start wave (where distance/challenge option allows), and your team name will be printed onto your bib.
There are no restrictions on our regular teams – you can be any mixture of charities / distances / funding types (i.e. Self Funding, Charity Sponsorship or Mixed Funding), and can have any number of members (even 1!).
Even if you are not fundraising for the same charity, you can still create a challenge team with 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.
If there is a charity you would like to fundraise for that does not appear on our list, we ask that you speak with your preferred Charity about what you would like to, and ask them to register with us via our short contact form which can be found on our website page www.ultrachallenge.com/the-charities/
Once they’ve registered with us, it will take about 5-7 working days to add them onto our registration forms, and you can then sign up to your chosen challenge in aid of them.
Alternatively you can raise for one of the 600+ charities for 2025 challenges we are currently already working with (see our list HERE>>>), or you can Self Fund your place and fundraise for them independently with no fundraising commitment.
Please note: the above is relevant for Charity Sponsorship or Mixed Funding places only. If you are entering as a Self Funder you can fundraise for any charity of your choice (only if you want to) & we do not need to be informed.
