I used to do a lot of charity raft races Cripps but now I just donate rather than participate I would have no trouble walking the marathon as I spend most of my working life walking from one place to another but I think after a few miles I'd be needing resuss if I ran it .
I did have a plan a couple of years ago to do some sponsored pole sitting in the Thames estuary for a week in aid of the RNLI but the missus said she wasnt prepared to miss her weeks holiday to watch me sitting up the top of a telegraph pole in the mud so I just signed up as a Shoreline member instead but its a regular donation so every bit helps.
