A message from founders, Jamie & Sam.

Taking on a multi-day ultra in a far flung corner of the earth is one of the greatest experiences in the world. The sense of achievement you feel after grinding through each day, and the camaraderie you build with your fellow participants in a remote desert, jungle or mountain camp is what makes competing in the global Ultra X series truly unique.Our goal is to enable more people to have these experiences every year, to champion the sport, and to make the world of ultra more accessible.Any race organiser can lay a course and handout water, but what sets us apart is our care and our friendliness. To us, you’re not just a number, you’re a name and we will do everything we can to make your experience with us as awesome as possible.We look forward to welcoming you to an Ultra X soon.Jamie and Sam
