Overview

• Speaking at a Puma event in Tokyo, Usain Bolt said he is "not worried" about anyone breaking his 100m and 200m world records in the near term.
• Bolt tipped Jamaicans Kishane Thompson and Oblique Seville to go 1-2 in Sunday’s 100m, positioning them ahead of defending champion Noah Lyles.
• Research funded by Puma and led by Wouter Hoogkamer projected Bolt would have run about 9.42 for 100m in today’s carbon-plated super-spikes, a finding he said he agrees with.
• Bolt acknowledged that advances in shoes and track surfaces could eventually bring down his marks, though he believes current athletes are not yet at that level.
• Australia’s 17-year-old Gout Gout debuts at worlds in the 200m ranked 16th after lowering the national record to 20.02, with his team limiting media access as he manages the jump to senior competition.
