Chattanooga woman is going to run 7 Bridges Marathon in high heels

Runners pass Coolidge Park with the Tennessee River in the background. The 7 Bridges Marathon and 4 Bridges Half Marathon, along with a 5K run were held simultaneously Sunday October 16, 2016 along the Tennessee River in Chattanooga.

Irene Sewell will strap on her high heels Sunday morning and run a marathon.

She'll take off alongside runners in their Asics, Nikes and Adidas at this Sunday's 7 Bridges Marathon with six pairs of heels, attempting to break a Guinness world record.

"I read an article about a lady in London who had attempted this a few years ago," Sewell said. "She didn't ultimately get the record, but I thought, 'Hey, I should try that.'"

Sewell will have to finish in less than 7 hours and 30 minutes to break the record. She'll have at least two people alongside her to carry the extra high heels and will change them out every 5 miles to limit breakage, possibly causing injury.
