Slow off the blocks, the sprinter from Odisha came into her elements midway into the 100m lane, edging past her state and teammate Srabani Nanda just before the finish line with a time of 11.68 seconds, not very far from her personal best of 11.62.
"I feel really relieved. I have been training really hard, three times a day," Dutee said dedicating the win to sports minister Sarbananda Sonowal.
The Railways sprinter, who had won 100m and 200m double in National Open Athletics Ranchi 2013, was banned since last summer after failing a hormone test.

Top Indian athletes Lalita Babar (3000m steeplechase), Inderjeet Singh (shot put) justified their reputation to shatter two meet records, while a third was set by promising Haryana javelin thrower Neeraj Chopra.
The timing was enough to better last year's record of 10:08.50 by teammate Sudha Singh who stood second.
"I was extremely cautious as I did not want to injure myself but at the same time I was confident of a record and make my department proud," the Railways athlete told PTI after her win.
Inderjeet Singh, who has also qualified for Olympics, threw 19.82 metres to erase Bahadur Singh's 12 year old feat of 19.59.
