It has been a lifelong ambition to swim the channel. So I'm going to do 3.

Over the Bank Holiday in May 2011, I swam the Bristol Channel from Ilfracombe to Swansea. It was just under 32 miles after going off course a couple of times and was the equivalent of 2240 lengths of a standard swimming pool. No stopping, no wetsuit. I set a time of 21 hours 46 minutes missing the record set by Gethin Jones by just 7 miniutes.

So now preparation is underway for Challenge 2 which will be the English Channel to France and back (46 miles) and then the Irish Sea which will be just over 90 miles.

This is being done in aid of "Help the Heroes" with part or all matched for "Cancer Research UK"
