Hey Mike, I've only been posting here about a week and I'm in pretty similar situation. Don't worry about 2 miles being such a work out. My first ride was around 2 miles too and I sure was winded at the end of it. This was three weeks ago. Yesterday I decided to take my new bike to the LBS to get something checked out and it was around 2.5 miles and I didn't even notice the ride really and I wasn't winded at all. When everyone says tha you will be up to long rides in no time, they really aren't kidding.
