Chebet’s run which included a 27.11 final 200 was one of the highlights on day 1 in Tokyo, alongside an epic gut-it-out win from Ryan Crouser in the shot put (his fifth consecutive global title).

Americans won the 100, 200, 400, and 110 hurdles, while Kenyans swept the 800, 1500, and steeple. Olympic champs Karsten Warholm (47.35) and Mondo Duplantis (6.06m) won the 400 hurdles & pole vault.

Thomas ran 21.94, which improved on her 21.98 from Thursday. McLaughlin and Benjamin both cruised in their 400 hurdles heats.

Reekie negative-split her way to a big 800 win, while Thompson obliterated the 100m field with a world-leading 10.85.

Lausanne entertained from start to finish as we saw a super-fast men's 1500, a wild men's 5000 with the fastest penultimate lap in history and a whole lot more.

One of the greatest records in all of track and field is now 40 years old and no one one has even come within four feet of it. Read all about it here.
