NEW: Man runs an entire marathon in jeans, averaging just over 6 minutes per mile.
Insane.
"Overdressed on the bottom and underdressed on top!"
The man, Truett Hanes, recently broke the world record for the most amount of pull-ups in a 24-hour period (10,001).
"Janet Rono would go on to win the Austin Marathon for the women and beat me by a minute. Tried to hang on, but she's simply too strong," Hanes said on IG.
Hanes finished in 2:42:51.
