Cassandre Beaugrand and Matt Hauser both claimed a third win in this year's World Triathlon Championship Series in London, where British hopes were hindered by crashes on the bike. World champion Hauser won in 50 minutes 28 seconds, with Portugal's Vilaca three seconds behind the Australian on a course consisting of a 750m swim, 20km bike ride and 5km run. Hungary's Csongor Lehmann was third - eight seconds behind Hauser - while Yee was more than a minute back in 14th and compatriot Max Stapley 12th. Olympic champion Beaugrand won the women's race in 56mins 6secs, five seconds ahead of Germany's Lisa Tertsch, with Sweden's Tilda Mansson 15 seconds adrift. Both Vilaca and Hauser were in the lead group throughout, before Hauser pulled clear around the final two corners.
