2.5Km is the new mile in the pool

Hooray for Marie, Rachel and I. Swimathon weekend was a success. We swam our 2.5km in just under an hour and raised some decent coin along the way for Marie Curie: http://www.mariecurie.org.uk/.
Will we keep up our swimming?  Maybe if we're mad enough to sign up for this: http://www.greatswim.org/Events/British-Gas-Great-Scottish-Swim/
