Last time I swam against Malaria, I did 10K, but due to shoulder knack I'm stuck with shorter swims. But don't think that means easier. This time i'm gonna do a 400 IM, no fins and all legal turns. And if I mess up I'll start again from the top until I get it right.
This year there is an added bonus. For every bed net that you purchase (aka $5 donated) you can get a free suit from Speedo. More information here http://www.worldswimagainstmalaria.com/FundraiserEvent.aspx?FundraiserEventID=1
