Ayesha Clarke, of Hartford, ran track in middle and high school. She was a sprinter, and especially enjoyed relay races. She also ran track in the Junior Olympics. Clarke is 31 now, an auditor with the state Department of Revenue Services, and the mother of two children, ages 4 and 3. Like many young mothers her age, she doesn’t exercise as much as she used to, but she has noticed a difference between women who exercised as teenagers, and women who didn’t.
