70 year old woman sets new records for the 3k and 5k

Just nine days after turning 70, Marie-Louise Michelsohn ran two new world record times for the 3,000 and 5,000 metres. Representing the Central Park Track Club-New Balance, Michelsohn wasn't deterred by Monday's windy conditions at Icahn Stadium in New York (17th Oct 2011). Running the 5,000 metres 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.
