Joe Jonas was spotted running through the streets of San Antonio, Texas yesterday.
He was participating in the iWin Joe Jonas Fun Run 5K race, but it wasn't just a casual run down the block - Joe had a bunch of tween girls following him and three security guards running around him!
The Jonas Brothers were in town for the San Antonio part of their World Tour. Tonight they'll play in Houston and tomorrow they'll be in New Orleans.
How does Joe have the energy to run and perform?
Check out more photos from the race, including one with Joe and San Antonio Spurs basketball player, Bruce Bowen, in our See Joe Run photo gallery.
