Hyde Park once again plays host to the London leg of the World Triathlon Series, the fourth event of the eight-race calendar. The famous venue provides the ideal backdrop for both the men's and women's sprint triathlons - fast and furious action is anticipated, with both races taking place on the same afternoon.

The Brownlee brothers go head-to-head in the men's race and lead British hopes. The sprint distance is the one event in which Jonny has been able to get the better of elder brother Alistair in recent years so it should make for a great contest.

2013 world champion Non Stanford makes her 2014 debut as she returns from injury but she faces tough competition from fellow Brits Jodie Stimpson, who leads the series, and two-time world champion Helen Jenkins. Show less
