The failure of Michael Johnson’s attempt to transform track and field, the Grand Slam Track league, hovered over big swaths of the sport’s world championships this week.

Anna Hall joined Jackie Joyner-Kersee as America’s second winner of the world heptathlon title, wrapping up a wire-to-wire endurance test with cruise into the finish line to celebrate her biggest victory.

World champion Katarina Johnson-Thompson's Olympic bid ended early and abruptly on Wednesday when she collapsed to the track during heats for the heptathlon 200 meters.

World champion the Netherlands is out of the women’s handball competition at the Tokyo Olympics after a 32-22 loss to France in the quarterfinals.

(CNN) - Despite her unquestionable talents and potential, much of Katarina Johnson-Thompson's career has been defined by heartbreak. "It was after the high jump in London in 2017 and after the long jump in 2015 in Beijing. Johnson-Thompson amassed 6,981 points over the course of the two-day heptathlon event, beating Jessica Ennis-Hill's British record which was set when she won gold at London 2012. This has been my dream, 7,000 points I've spoken about in the past as one of my main career goals. "She's definitely raised the bar and I'm just glad I've been able to follow and step up."
