“That day, for no particular reason, I decided to go for a little run. And when I got to mile 20, I figured, since I'd gone this far, I might as well just keep on going.” — Forrest Gump (if he ran the Chicago Marathon)

Good luck to everyone running tomorrow's Chicago Marathon! May your legs be strong, your miles fly by, and your run be a little shorter than Forrest's. 😂

🏃 26.2 miles. For no particular reason.
