Humanity Direct Amersham Ultra routes

This race is for a fantastic cause, with previous years having raised up to £8,000 for Humanity Direct, a charity which helps children in developing countries get the medical care they vitally need. As such, your £58 race fee is a donation to a great cause.

This course will take you throughout the picturesque Chiltern Hills and through some of its most notable valleys - Misbourne and Chess.

The ultra is split into three races: walkers, runners, and elite runners. Each race starts at a different time, with elite runners targeting a time below 6 hours.

The route itself will consist of 4 checkpoints, doubling up as aid stations. Checkpoints will consist of refreshments and food, as well as health checks. Details of these can be found below:

Start - Checkpoint 1: 11.6KM
Checkpoint 1 - Checkpoint 2: 6.9KM
Checkpoint 2 - Checkpoint 3: 14KM
Checkpoint 3 - Checkpoint 4: 7.2KM
Checkpoint 4 - Finish: 7.2KM

The route is clearly marked throughout and there will be on course marshals, however you will still need consult your map.

Too many children suffer or die from a lack of medical care simply because their families can't afford the treatment they need. We want to change that by enabling donors to directly fund life saving and life changing operations for children in developing countries.

    Did the Amersham Ultra - Elite Runners (Under 6 hours) in 2020

    Lovely friendly race. Very well-organised and the course was really well marked. Not too muddy given the terrible conditions everywhere else! Would be a great first ultra or just a great day out as it's good value and easy to get to the start. And all for a fantastic cause.

    Did the Amersham Ultra - Elite Runners (Under 6 hours) in 2020

    Really enjoyed the day. Beautiful route, lots of fun in the mud, hardly any road sections. Great organisation by XNRG. Thoroughly recommend.
  • Did the Amersham Ultra - Runners in 2019

    A brilliant, yet challenging, day out in the Chilterns. Heartily recommended for 'ultra' beginners.
  • Did the Amersham Ultra - Runners in 2019

    All in all a good event. This is a highly runnable course, even when conditions underfoot aren't ideal (as was.the case this year). The only real complaint I have is the difference between the actual route and the information provided beforehand (on internet and maps provided on the day), as there were a couple of deviations that had a real mental impact as I had run the course during training. It should also be noted that the course is about 48.5km, not 50k as advertised.
