Herron was a cross country state champion at Westmoore High School, but a series of stress fractures cut her collegiate career short at the University of Tulsa.
She had quit running but started training again in 2005 and has won six marathons since. Herron is coached by her husband and she represented the United States in the Pan American games last fall.
Herron also ran a personal best marathon time of 2 hours and 37 minutes at the Olympic trials this year. She has Olympic aspirations for 2016.
“This year it took 2:26 to make the Olympic team,” Holt said. “She is going to have to improve about 10 minutes in four years, but four years ago her best time was 2:46 so she has improved nine minutes basically in four years. If we can stay on the same track, you never know.
“If I can keep her healthy, I think she will be pretty good in four years.”
