Hoping to raise money for Mental Health Matters

Hi, my name is Oliver and I am challenging myself by taking part in the Tough Mudder challenge in Birmingham. So far I have been working on my fitness for nearly 2 years and during this time I have gone from extremely overweight at the age of 16 weighing 120kg and have now lost 32kg and want to now challenge myself further hoping to raise £100 in the process for Mental Health Matters. Please help me achieve this goal!
