Raising money for a great cause by walking 100km (continuously) from Putney Bridge to Henley on Thames which should take just under 24 hours, with the occasional sock change and refuel stops.

It will be a challenge and we're not sure what we're going to talk about the whole time (topic suggestions welcome in the comments) but we're going to finish and hope to raise money that will go to helping improve life for people with Parkinson's and help fund research into finding a cure.
