A one-day, 50km ultra raising funds for a great cause. Choose to pay for your place upfront, or bag a FREE spot if you commit to fundraise. All funds will go to Humanity Direct, a charity changing the lives of children needing medical care in developing countries.

New this year you have the option of the full 50km ultra marathon, a 25km half ultra or complete the full ultra as part of a team of up to 5 people!

If you choose to take part as a team you will be given one race number and timing chip that your team will need to get from the start to the finish. It's up to you which part of the course each team member will cover (each person can run more than one leg) but note that you can only hand over at the standard ultra checkpoints and also that it is your responsibility to transport your team members to their handover points. 

You will enter on behalf of your team and we'll ask you for the names and other basic information of your fellow team members. You can make changes to your team up until close to the event. Our usual cancellation/deferral rules apply but requesting either will be on behalf of your entire team.

More Information

Join us for the first in our XNRG charity single-day series for 2024. Within a stone's throw of London, you'll race across the glorious Chilterns - all fully supported and with bags of XNRG encouragement and atmosphere. It's ideal for anyone wanting to 'step up' to covering an ultra distance, as well as being great training for multi-stage events. And it's all for a good cause.

how it works

It's simple. The entry fee is donated to Humanity Direct, OR, if you prefer, you can enter for FREE and start a fundraising page instead to raise as much as you can (minimum donation: £65/£95 for teams). 100% of donations go towards children's operations and medical care in developing countries through Humanity Direct.

You can also opt-in to receive a quality finisher's t-shirt for an extra £5.

Why we do it

In 2019, Humanity Direct raised £24,000 through the three XNRG Humanity Direct Ultras, funding life-saving and life-changing operations for 35 children. We're hoping to raise even more in 2024!
 

“The support we’ve had from XNRG has been phenomenal. Thanks to you we’ve rolled out a vital eye-testing programme for children in rural Uganda with over 600 children receiving free glasses so far. Your donations and dedication have also helped us continue to provide life-saving and life-changing surgery for children whose families are live on less than a $1 a day and who would never be able to afford the medical care they need.  XNRG ultras truly do change lives!"

- Nick Swift, Humanity Direct’s Founder

 

Entries

Entries will close one week before the event (or when full). A waitlist option will be available if the event becomes fully booked.

Navigation and Support

The event is supported by our course manager and his experienced on-course crew to ensure you have a great event. A fully qualified medical crew will also be there to give first aid and manage any serious medical problems in cooperation with the emergency services.

Aid stations

There will be checkpoints at regular intervals, fully stocked with water, and sweet and savoury food to keep you fuelled. There are four checkpoints for the ultra distance and two for the half ultra.

Due to the risk of cross-contamination, we can't provide checkpoint food to suit all dietary requirements. If you require special food or snacks to suit any allergies or vegetarian/vegan diets, please bring your own. Put them in containers, marked with your name and checkpoint number and give them to the checkpoint teams at the start of the race.

Trees Not Tees

Event T-shirts are no longer included in the cost. The cost of T-shirts goes to Trees not Tees and a tree will be planted instead. You have the option of purchasing a T-shirt when entering the event, if you'd like one.

Reviews

A big thank you to everyone at XNRG and Humanity direct for a wonderful day yesterday, you even sorted the weather!! It was a beautiful route and really well organised and signed. Thanks to all the volunteers and everyone who made it possible.

I just wanted to say how much I enjoyed my first ultra on Saturday! Wasn’t quite prepared for the mud... but at least the weather was lovely! I particularly enjoyed how kind and supportive everybody was, and the great spirit everybody had throughout the whole day.

A big thank you for another great event.
Great organising, great support, fab checkpoints with picnics, love the course (if a bit muddy).
I love the atmosphere of your events, both the participants, crew and supporters.

We can't wait to see you there! Questions? Say hello on info@xnrg.co.uk
