Thanks again all.

I got up and ran using the interval concept this morning. Definitely gives the lungs a work out. I also talked to the shop/ride guys this morning and they don't seem at all surprised or concerned that I'm getting dropped at this early juncture. Basically the comment was "this is Boulder and everyone is a professional athlete" *sigh*. They promise me that there will be slower riders as the weather warms up; apparently they suspect I'll be able to keep up with the mechanic's pregnant wife who will be joining us soon (I'm not sure if I should consider that a good thing or a very very bad thing ).

On a happy note my new bike is built and hanging, begging to be ridden, in the shop. Darn it's perdy! NEED TAX RETURN NOW!!!

Anyway, I'm going to give intervals and increased riding a few weeks to work their magic and if I'm not improving I promise I'll go see a doctor (for the first time in ~10 years might I add!! )
