I can’t believe what I have just done. I have signed up for the Great London Swim! This is to complete challenge 3 of my bucket list: swim a competitive race (at least 1 mile). On the 18th July I will take a plunge in the shadow of the O2 Arena and Canary Wharf, then swim alongside the ExCel centre. This is a 1 mile swim (1.6 km) in the open water.
