This popular race is especially good for those looking for a supportive event for their first ultra within easy reach of London.
As with all of our events, everything is taken care of at the Chiltern Challenge so you can focus on the experience! We’ll provide transfers from the station, free parking, free photos, changing facilities and heaps of tea and cake.
The XNRG Chiltern Challenge is a unique chance to get a place on an amazing one day ultra for FREE if you fundraise for a Humanity Direct patient, or donate £58.
In 2019 Humanity Direct raised £24,000 through the three Humanity Direct Ultras, which helped fund life saving and life changing operations for 35 children and we are hoping to raise even more in 2021.
So, how does it work?
It's simple. The entry fee for the one-day ultra-marathon is donated to fund a vital operation or, if you prefer, you can enter for free and start a fundraising page instead and raise as much as you can, with a minimum of £58.
“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 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
Stretching from the River Thames in Oxfordshire to Hitchin in Hertfordshire, the Chiltern Hills are a spectacular Area of Natural Beauty boasting some of the finest protected countryside in the UK.
The well-marked circular route will start and finish at Princes Risborough School (HP27 0DR), incorporating four checkpoints, approximately 10km apart.
Using National Trails and Footpaths, there are clear signposts and post discs, as well as our signs and confidence tape. We'll also give you a handy map, designed to help on any tricky sections. We recommend familiarising yourself with the route before the start of the race.
There will be four checkpoints at regular intervals with water and food - please bring your own cups.
Due to the risk of cross contamination, we cannot provide checkpoint food to suit all dietary requirements. If you require special food or snacks to suit any allergies or vegetarian/vegan diets, can you 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.
