Andre De Grasse is on a roll before the start of the Canadian Track and Field Championships on June 22 in Langley, B.C. He won his first 100m of the season at the Bislett Games, then saw a season best time in the 200m in Paris. Meanwhile, Sha'Carri Richardson is ready to redeem herself at the U.S. Nationals, looking to take back the 100m title she won then lost in 2021 after testing positive for marijuana. --------------------------------------------------------------------------------------------------------------------------- http://cbcsports.ca is your home for Canadian athletes, fans and the Olympic Games.
