I have talked to my fair share of gritty runners, but Lisa Tuckwood may be the grittiest.

Maybe it's her background in the Army or maybe it's just how she is, but regardless, Lisa is one tough lady.

She's always been athletic, but didn't start running races until 2015 -- three months after back surgery.

Her record speaks for itself. No DNFs, but enduring some incredible challenges.

She's got a 200-miler this month in Georgia, followed by a couple of hundos later this year.

Feel inspired. I was.
