Price options

The registration fees and fundraising targets are different for each distance, but you'll have the following options:

  • charity sponsorship – you pay a small registration fee, have a minimum fundraising target and we cover the cost of your event place
  • mixed funding – pay half of the event place cost yourself, have a lower fundraising target, and we pay the balance of the event place cost
  • self fund – you pay the full cost of the event place then fundraise as much as you can. There are no set targets or deadlines, and there's no cost at all to us.

COVID secure measures

The Ultra Series team are committed to running COVID-safe events and ran one of the UK's first 'COVID secure' mass participation challenges in 2020. They'll also be implementing standardised measures to keep all participants safe whilst on each challenge in 2021. You'll see special social distancing requirements and hygiene measures in place across many elements of the events, ensuring each Ultra Challenge is as low risk as possible for everyone involved.
