XNRG 2022 events now open for booking!

Enjoy, endure and get the experience you need of racing in two XNRG UK multi-day events.  The package combines two of our most popular events at a combined discounted rate: the Pilgrim Challenge and the Druid's Challenge.


When you’re training for desert marathons, we know how important it is to have the opportunity to race in a way that helps you prepare physically and mentally. Whilst we can’t guarantee Moroccan sunshine, we will provide a challenging yet beautiful course and multi-day environment, with all your needs completely taken care of, so you can focus on the experience. 

You’ll get to test out your kit, meet others preparing for the MDS, make friends and form tent groups. You’ll even meet people who’ve done the race — a great way to find out what works and what doesn’t. The XNRG MDS Package really is the perfect way to train for your six days of Saharan endurance.

XNRG founder and MDS runner Neil has shared his top tips for preparing for the Marathon Des Sables. Download and read the guide >



When XNRG founder Neil Thubron ran the Marathon Des Sables in 2009, he felt frustrated that there were no events in the UK to help people prepare for the format of the race through the Sahara - both physically and mentally.

‘There were no multiday ultras on the calendar,’ Neil says. ‘So I decided to put one on, and it proved really popular — the rest is history!’

The first XNRG event was the three-day Druids challenge in 2010. Since the first Challenge, over 500 MDS competitors have used XNRG event to get them ready for the desert. ‘We provide the complete package so that once the competitor arrives they don’t have to do anything apart from run,’ says Neil.

Following six years of successful events, XNRG is now known for producing the highest quality multi-day ultra running experiences. With a family feel, everyone is looked after from the moment they arrive to the moment they go home.
