Well, in the end I managed it, and despite 4 miles of cramp-induced hell and a delirious stagger to the finish I managed to post a time of 3:35:52.

A huge thanks to everyone that came to watch, the encouragement of the crowd made it a fantastically unforgettable day.

Thanks for your generous contributions, we're almost at the target now and if you haven't got round to sponsoring me yet there is still time, and anything you can give is greatly appreciated.

Médecins Sans Frontières are an independent humanitarian aid organisation, committed to providing medical aid where it is most needed, regardless of race, religion, politics or gender. Please use this page to give whatever you can to this worthy organisation, and remember, that if you are a UK taxpayer, you can claim Gift Aid on your contribution too.

Many thanks,

Jamie
