Multi-event world champions have rough day at Tokyo Olympics Today 01:33 am JST Today | 07:53 am JST KJT was desperate to avoid a DNF at the Olympics. After injuring her lower right leg rounding the bend in the 200-meter event, heptathlon world champion Katarina Johnson-Thompson found herself sitting on the track with medical staff rushing to her assistance, including one pushing a wheelchair. She waved them off, got up and started jogging gingerly down the home stretch, crossing the finish line with a stride more like a race walk than a sprint. After bravely avoiding a Did Not Finish in the result column, she recorded a DQ instead — disqualified for stepping out of her lane.
