I have decided to do the London Marathon. It is now 5 years since I challenged myself to do a Half Iron man and I think this challenge is even more daunting but also exciting.As with my Half Iron man I am raising money for The Cure Parkinson's Trust.

 As a doctor I care for my patients with Parkinson's and see what a devastating disease Parkinson's can be. It is also very close to my heart as one of my best friends Tom Isaac developed Parkinson's when he was 26. He has sadly died but he has left in his memory the amazing charity he started which raises money to find a cure for Parkinson's. Tom was one of the most inspiring people I have ever met and I miss him. When I am running I will draw on his strength and courage to get me through.
