Ore Oduba presents live coverage from Leeds, where the fourth leg of the World Triathlon Series is taking place. Jonny Brownlee is aiming to get his world title challenge back on track after a dramatic race inJapan last time out, where he ended up having to carry his bike after a crash in the cycling phase. Jonny is joined by brother and Olympic champion Alistair, who makes his first World Series appearance of the season. The pair will certainly not lack for support as Leeds is their hometown but their rivals include five-time world champion Javier Gomez, along with current world champion and series leader Mario Mola. Leading the charge for the British women's team is former world champion Non Stanford but she faces stiff opposition in a high-quality field, not least in the form of reigning world champion Flora Duffy, who showed she had shaken off early-season injury problems with victory in the most recent race in Yokohama.
