Humanity Direct Tring Ultra: a 50Km, one-day ultra marathon within easy reach of London, all in aid of funding life-changing operations for children in developing countries.

Perfect for anyone looking to take their running to the next level. Explore the picturesque Chilterns, a stone's throw from London. Even better, it's FREE to run, if you commit to raising funds for Humanity Direct.

As with all our events, we'll take care of everything so you can focus on walking, running or jogging the trail. Transfers from the station, free parking, free photos, changing facilities, and plenty of tea and cake are all included.

The Humanity Direct Tring Ultra is a unique opportunity to race for FREE on an amazing one-day ultra if you pledge to fundraise for a Humanity Direct patient or donate £58. Do something amazing and have a great day out with us.

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.

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

Pricing options

Standard entry - £58

Or FREE, if you commit to raise funds for Humanity Direct.

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.

Why we do it

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!

“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

Another well marshalled and well run Humanity Ultra. The volunteers at the checkpoints are absolutely amazing and very helpful.
The course is flat earlier on and gets hilly at later stages. it is well marked all the way through with some amazing views across the Chilterns.
I would recommend this for anyone looking to their first ultra.

This was my first Ultra, so I wasn't entirely sure what to expect.
I was greeted early on and upon finding out this was my first, offered much helpful advice and the promise of a certificate upon completion to commemorate my achievement, which was a really nice touch!

There isn't a cut off time, which takes so much pressure off the day. There are 3 staggered starts, the walkers, run-walkers and elites. I started with the walkers and was first passed about 15km in. It was actually nice as it means the field spread out and the slower of us weren't running the vast majority alone.

Aid stations were good, as a vegan it lacked a lot of options for me, but I appreciate I'm hard to cater for. salted tortilla chips kept me very happy!

The route was exceptionally well marked. As someone with no sense of direction I worried about this and getting lost, but I needn't have. just when you started to question if you were on the right track, confidence tape appeared, or a helpful orange arrow on the floor.

The weather wasn't on our side, so the latter part of the course became slippy in places, but it was a very beautiful route with very minimal road sections. The mix of pancake flat canal sections and challenging hills was about right in my view. Although with my knee slowly packing up I'll admit i was cursing the last 5km home stretch.

I'd highly recommend it to anyone looking for a first ultra.

2018 A well organised event, friendly helpful organisers and the feed stations were well stocked with a variety of savioury and sweet treats. Only issue was the lack of vegetarian savioury options and the massive hill at the end.
