Event overview

If you're keen to take on a proper challenge, shape up, re-energise and support an important cause, this ultra will help you go further than ever before - whether you walk, jog or run your way to the finish line.

You'll be supported all the way from the moment you sign up with an event app, online guides, forums and training walks. On the challenge there are safe venues, camping options, fully signed routes, chip timing, marquee rest stops, fantastic food and drink and expert safety, medical and welfare teams to get you over the finish line where you'll receive a huge cheer, medal, glass of fizz, t-shirt, massage, BBQ and more!
