Set within the scenic Cotswolds, Tough Mudder South West is a truly daunting challenge over a 10-12 mile obstacle course designed to test physical strength and mental grit. With some of the UK’s deepest, darkest mud, soul-crushing terrain and obstacles designed to test them to their limits, participants will think they've stumbled into hell. So why would Sarah Jones volunteer to undertake such a challenge?

"I have a personal connection to Smile4Wessex as my uncle suffered with brain tumours. Jess and my Aunty Diane set up the Jurassic Walks to support the charity. This year was particularly important to my family as tragically last year my uncle was killed in a motorcycle accident when he was hit by an uninsured driver. Therefore I would like to keep raising money for this charity, which meant so much to Jess, in his honour."

We're sure you will do Jess proud, Sarah, and wish you all the best for the challenge.
