Olympic medallists Alex Yee and Beth Potter will compete for Great Britain at the World Triathlon Championship Series event in London this weekend, with the action broadcast live on the BBC. The London leg is part of the flagship elite series featuring the world's top triathletes, and matters as both British stars look to return to winning form on home soil ahead of the season finale in Pontevedra, Spain, in September.

Potter, who won bronze at the Paris 2024 Olympics, tops the current women's standings and world rankings after finishing on the podium in three of the opening rounds, including a win in Uzbekistan, though she was sixth in Hamburg and missed the Quiberon race for altitude training. Yee, the Paris 2024 gold medallist, is transitioning back to triathlon after a spell running marathons and track events, having finished fifth in Yokohama but failed to finish in Sardinia. Other notable contenders include series leader Vasco Vilaca of Portugal and Britain's Georgia Taylor-Brown, with the race taking place at ExCeL London on Saturday 25 July from 14:15 BST.
