She says it's still not good enough for her. She's coming back next year to try and set a course record.
Herron said she wants to win a marathon in every state. She's won nine so far.
"I want to get the course record. I ran 2:37 in the marathon, so I was not feeling as great today but I'd like to come back next year," said Herron, "Hopefully I'll do a little better and get the course record."
No rest for Herron. She's headed to Nebraska next Saturday to knock another state off her map.
