30-year-old Surekha soared to 4.15m to the surprise of the sparse crowd at the Jawaharlal Nehru Stadium to erase her earlier national record of 4.08m which she had set in October 2006 at Patiala.
The meet being the season-ending event, it was expected that the athletes would not be in their top form but Surekha, a mother of a four-year-old girl, was the exception as she left behind the disappointment of not making at Incheon Asian Games with a brilliant performance.
Surekha, who has dominated Indian women's pole vault scene, has broken her own national record many times in the past. She missed out of Incheon Asian Games after clearing 4.05m at Federation Cup in August while the qualification mark set by Athletics Federation of India was 4.15m.
"I was extremely disappointed at missing out at Asian Games. At Patiala (Federation Cup), I was under pressure thinking about Asian Games qualification. But today, I don't have any pressure as their was nothing at stake," said Surekha, the wife of former national record holder triple jumper Renjith Maheswary.
In women's 3000m steeplechase, Railway woman Sudha Singh made the most of the pulling out of Asian Games bronze medallist Lalita Babar to win gold in 10:08.50, breaking her own meet record of 10:09.04 of last year.
Sudha was over half a lap ahead of team-mate Priyanka Singh Patel who took silver in 10:35.86. Lalita started the race but pulled out after completing a lap.
