Under no pressure and expectations, Singapore's Dipna Lim-Prasad delivered her most sparkling sprint to date, shocking even herself as she smashed Prema Govindan's 29-year-old national 200m record of 24.54sec on Saturday.
"This is a big, big surprise," said the breathless 22-year-old after her 24.36 burst at the Singapore Under- 23 Open Track and Field Championships.
"I was just testing out my speed because this event wasn't my priority."
As it turned out, her spikes were working just fine - with no wind assistance - at the Choa Chu Kang Stadium.
In a thrilling photo finish, the Nanyang Technological University student pipped national 100m record holder Shanti Pereira to the line by just 0.21sec. Tyra Ree Summer was third in 26.39.
Shanti, 17, had equalled Govindan's 200m record earlier in July at the International Association of Athletics Federations World Youth Championships in Donetsk, Ukraine.
"I was in the lane in front of Shanti so it was intimidating hearing her footsteps on the curve," said Lim-Prasad, who also holds the national 100m hurdles and 400m hurdles records.
"Towards the end, I got in the zone and tried not to think about her."
Lim-Prasad's momentous run - her previous personal best was 24.61s set in 2010 - earned high praise from Govindan, who was her teacher during her Singapore Sports School days.
The 47-year-old said: "I'm glad it's Dipna who broke my record.
