Several open water swimmers swam extremely fast over the last few days in the Water Cube in Beijing.
In addition to Cassandra Patten making the finals of the 800-meter freestyle, Britain's David Davies made the finals in the 1500-meter freestyle in an incredibly quick 14:46.11 in the most impressive preliminary 1500 heat in history.
English Channel record holder Petar Stoychev dropped his seed time seven seconds to do a very respectable 15:28.84. Greece's Spyridon Gianniotis did an even more respectable 14:53.32 that, unbelievably, was not fast enough to qualify for the finals.
