Ranchi: Star sprinter Dutee Chand smashed her own national record, clocking 11.22 seconds in the women's 100m semi-finals on her way to the gold medal at the 59th National Open Athletics Championships here yesterday. A fortnight after failing to reach 100m semis at the World Championships in Doha, Chand, 23, surpassed her previous timing of 11.26s which she had set at the Asian Championships in April this year.

While she had equalled Rachita Mistry's 11.26 second effort at the Asian Championship, Dutee's time of 11.22 seconds in the semi-finals yesterday finally gave her the sole ownership of the National record. Dutee later clocked 11.25 seconds in the final to claim the gold, leaving Archana Suseendran and Himashree Roy in the wake. At Doha, she had managed 11.48 to finish a disappointing seventh in her heats.
