<p>I'm doing the 10km swim down the River Dart in Devon in September as a way of a) trying to replace rugby!&nbsp; b) raising money for Leukaemia Care charity.</p> <p>Training is tough: 2 hours in sea yesterday. I think the event may take up 3 and half /4 hours!</p> <p>If you could sponsor me to&nbsp;stay afloat all the way down that would be great, no matter how small the amount!</p> <p>Many thanks</p> <p>Joe</p> <p>&nbsp;</p>
