XNRG's mission is to help people challenge themselves and break through their mental and physical barriers, whilst providing peace of mind with expertly run events, going the extra mile for every competitor.
Our heartland is multi-day endurance events; we originally started to help people training for the world's toughest desert footrace, the Marathon Des Sables. Today, we welcome hundreds of competitors across our events, from single day ultra marathons to multi-day events.
We can't wait to welcome you!
