I was tempted to do it this year on my track only bike since crashing my road bike, but the minimum gear I have is 46X15, and was kind of concerned it would be a *****.

I totally kow what you are saying about attacking like hell on hills. I've been riding my track bike with a bunch of my roadie friends and feel like a dick when I make an attack up a hill, especially when we are on easy rides with a lot of beginners.
