It's cold out side. I woke up early. Got dressed grabbed the bike and headed out the door. Half way through the ride I started feeling sick. I turned around cutting it short and made it back to my house only to throw up on the drive. After that I immediately felt better. Maybe I over heated by over dressing? I don't think I'm sick. Has anybody else ever done this? It was there then when I stopped riding it was over. Maybe I'm allergic to bikes?
