Have a look at the funding options available to you:

Charity Sponsorship
 – you pay a small registration fee; do lots of fundraising and we cover the cost of your event place!

Mixed Funding – pay half of the event place cost yourself; fundraise a bit less and we pay the balance of the event place cost.

Self-Fund – you pay the full cost of the event place; fundraise whatever you want, with no set target or deadline, and there’s no cost at all to the charity!

When fundraising, we would advise that you set up a JustGiving page. It is the most effective way for you to fundraise! If you have any questions about this, please get in touch. 

Thank you to all Ultra 2023 participants
