Spin Class Woo! Woo!

So I decided to go to spin last night. I love the spin class because of the intensity. So there I am spinning away, sweating...part of me wanting to die...legs burning...then finally it's time for cool down...now that's where the problem begins. I start to feel the churning in my stomach...I tell myself just breath...there's only 8 minutes left...then I decided that I wasn't going to make it. I surveyed the room for a trash can, knowing I would never make all the way across the gym to the bathroom...ummm...sorry people by the can! So up came my mango I had eaten an hour ago. Does that mean I burned double calories...the ones on the bike and the ones in the can? Moral of the story don't eat before spin class, for everyone's sake!
