This weekend I had one of the wildest and best experiences I can remember. I ran the Ragnar Relay a 12 person relay race from Kingston, NY to the Bronx, 181 miles.
Packed in a van with five other sweaty people we ran, drove, laughed and ran some more for 24 hours straight. Sounds a lot less fun than it really was.

(Real Simple)

Needless to say, the other 24 hours for the weekend were spent feeling like this.
