The kings team are the ultimate experts in Marathon swimming. The Kings team has done so much open water swimming. Keven had swam the English Channel 34 times solo. He has swam in 6 English Channel relays and his list of open water marathon swims is staggering. Kathy has swam the English Channel solo but also 18 times as part of a English Channel relay team. Both Kathy and Kevin have completed the Triple Crown in open water swimming. Ian has swam the English Channel sub 10 hours twice, earning him twice the Centenary Cup, which is given to the ‘Fastest Swim of the Year by a British Person’ across the English Channel. Marathon swimming is a class of open water swimming defined by long distances (at least 10 kilometers) and traditional rules based in English Channel swimming. Unlike marathon foot-races which have a specifically defined distance, marathon swims vary in distance. However, one commonly used minimum definition is 10 kilometers.
