Marathon runner: Amy Doolittle-Crider

Amy Doolittle-Crider is taking her challenges one Columbus at a time.

The Louisville nurse-practitioner said she ran the 26.2 miles Saturday — with the fourth best time among women — as a tune-up for an Oct. 18 marathon in Columbus, Ohio.

But it isn’t as if the 35-year-old’s appearance in the “other” Columbus is the only thing she does to prepare herself for competitive running.

“I run about 70 to 90 miles a week,” Doolittle-Crider said. “The only problem is that I keep making it harder to get that runner’s high.”

Last April, both Doolittle-Crider and her husband packed up their two children, ages 2 and 6, to participate in the Boston Marathon.

Doolittle-Crider cited two primary reasons for competitive running.

“As a health-care professional, I see it as both a stress reliever and a health promotion,” she said.
