Recordholders Beware

Recordholders beware. Marie-Louise Michelsohn is 70 now.

Just nine days after becoming a septuagenarian, she added two new world records to her resume to bring her total count to nine.

Representing the Central Park Track Club-New Balance, Michelsohn wasn't deterred by Monday's windy conditions at Icahn Stadium. Running the 5,000 meters she first broke the world mark for the 3,000m en route. Her 3k split of 12:58 crushed the previous best, set by Elfriede Hodapp in 2006, by 26 seconds.

She finished the entire race in 21:59, shaving seven seconds off of Cecelia Morrisson's previous 70-74 age group record.

A mathematics professor at Stony Brook University on Long Island, Michelsohn came to running after the age of 50.

In an interview with the website Women Running Together a few years back, she explained her athletics background from her scholastic days. "I played tennis, but nothing else," she said. "I was busy studying. I put all my energies into mathematics. Both the Bronx Science and the University of Chicago weren't into athletics."
