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!
