Well the olympics this year saw the 10Km Open Water swim, or marathon swim as some call it, become part of the Shcedule for the first time ever.
Although watching it for two hours might not be everyone's cup of tea, the finishes in both the mens and the womens races were very exctitng!
David Davies won silver, and Keri-Anne Payne and Cassie Patten won silver and bronze respectivley.
