Star Indian sprinter Dutee Chand said she is determined to further better her 100m national record and achieve the qualification standard of 11.15s for the 2020 Tokyo Olympics. A fortnight after failing to qualify for the women's 100m semi-finals at the World Championships, Dutee completed a sprint double at the Nationals, clocking the fastest 200m time by an Indian this year, with a 23.17second burst. The 23-year-old also shattered the 100m national record with a time of 11.22 seconds during the semi-finals on way to the gold medal in Ranchi. She credited her success at the National Championships to her preparation for the Doha World Championships.
