For a limited time, we're offering the opportunity to participate in all three of our 2025 Humanity Direct races at a special price!

You can choose to book all three ultras or half ultras. The events include:

  • Amersham - 8th March 2025
  • Chiltern Challenge - 19th July 2025
  • Tring - 20th September 2025

Just like with individual race entries, all proceeds will be donated to Humanity Direct, helping fund essential, life-changing surgeries for children in Uganda.

Pricing

Ultra series

The entry fee will be donated to fund a vital operation, or alternatively enter for FREE, if you commit to raise funds for Humanity Direct.

If you're fundraising book now through our system, then visit Humanity Direct's website to register yourself.

Please note: a 2.5% service charge, levied by the registration software, will be added to your total. We are using a new entry system that takes payment through the secure system Stripe. No payment information is retained by Extreme Energy, or our entry system tool.

If for some reason you are not able to make the event you have entered. The XNRG refund policy is that we will give you 70% refund of your entry fee up to 1 month before the start date of the event. You also have the option (1 month before the date of the event) to get a 100% transfer credit to another one of the other Humanity Direct 1 day events, or you can donate your entry fee to the charity. All entry fee money goes directly to the charity and directly to helping children with life changing operations. These options you can execute on your Ultrabritain entry page.

After this time we are sorry there will be no refunds or transfers to future events. Refunds will be to your booking credit card.
