Couple of the biggest happenings on the track last couple days,
Karsten Warholm of Norway! The Viking! Smashes his own world record in the 400 hurdles with USA's Rai Benjamin, both running world record times pushing each other to the limit, Warholm dropping below the 46 second mark, astounding! Race of the Olympics so far, instant classic.
Elaine Thompson-Herah becomes the first woman to win back to back double 100m 200m Gold, none had anything for her top-end speed, Shelly Ann Fraser-Pryce "mommy rocket" gave her a good run mid-way thru the 100, but that was all. She becomes the first woman to accomplish this feat and Jamaica now has a Lady Bolt!
Lamont Marcell Jacobs won 100m Gold for Italy, the only Italian man in history to have won the event.
