Katarina Johnson-Thompson begins her bid to succeed retired champion Jessica Ennis-Hill. Gabby Logan introduces comprehensive coverage of the second day's action at the World Championships as Katarina Johnson-Thompson begins her bid to succeed the retired Jessica Ennis-Hill as champion. The 24-year-old has yet to turn her immense promise into major outdoor medals, but she has benefited from a move to France and set a personal best of 6,691 points in the run-up to these World Championships. She expects to make a strong start in the sprint hurdles and high jump. Nonetheless, more athletes have emerged to fill the void left by the retired Ennis-Hill and Brianne Theisen-Eaton, and Olympic champion Nafissatou Thiam recently became the first heptathlete in a decade to score more than 7,000 points. There are plenty of other Brits in action, including European indoor champion Asha Philip in the women's 100m first round, Olympic finalist Matthew Hudson-Smith in the men's 400m heats and Rio 2016 bronze medallist Sophie Hitchon in hammer qualification. The commentary team is led by Steve Cram, with expert analysis from Michael Johnson, Denise Lewis and Colin Jackson.
