More Information
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.
Humanity Direct
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!"

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.
Aid stations
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.
Getting there
A stone's throw from London, there are a few options for reaching the race.
By train
Trains with Chiltern Railways run from London Marylebone every half an hour, taking between 30 and 58 minutes to reach Princes Risborough. Trains from Birmingham leave approximately every 30 minutes and take around 1hr30. We'll be running a minibus shuttle to and from the station in line with registration and finish times.
By road
Princes Risborough is about a 20 minute drive on the A4010 from Junction 4 of the M40 (High Wycombe) or 20 minutes on the B4009 from Junction 6 of the M40. There will be free parking all day at the school.
Testimonials
Hi, I don't usually respond to organisers after an event. I just wanted to say thanks for organising such an amazing first ultra. The race was superbly organised , well planned , Marshall ands food stops were excellent. I can assure you I will be running in your events again and recommend them to others. Thank you and your team for making the chilterns ultra such a great run.
Hi everybody I would like to congratulate XNRG on a superbly well run event in the Chilterns. It was a fabulous day out in stunning countryside. Everything went like clockwork, registration, briefing and the course was marked perfectly with tape, signs and sometimes quite elaborate pictograms sprayed on the ground making the maps supplied only necessary as an overview of the route. I find it quite mind boggling that you can plot and mark such a varied and interesting course in 31 miles of countryside, check it and then clear up afterwards. It made the entry fee worth it alone.
Just wanted to say thank you to everyone who helped with this event yesterday. It was my first ultra and I absolutely loved it! The fantastic organisation meant all I had to do was concentrate on getting myself round the distance! The malt loaf and coke at the checkpoints were a much needed treat! Thanks again.
We can't wait to see you there! Questions? Say hello on info@xnrg.co.uk
