About the British Gas Great London Swim

How it works
Now in its fourth year the event is the biggest open water swim in the south of England. Around 5,000 participants took the plunge in both 2010 and 2011, in waves of approximately 300 people every half an hour.
The one-mile course starts and finishes on dry land with a run or walk into the water.
Your timing chip wonn’t start until you cross the start mat so don’t worry about taking your time and letting more experienced swimmers go first.
