So I bought a pista 2 weeks ago with the thought that I would use it as my everyday commuter and then switch to the road bike on the long treks with my buddies. Plus riding the 48x16 should have made me the stronger rider (I was thinking resistance training)

This week with the exception of yesterday I rode just the fixie. Yssterday though being an informal century for my friend's birthday and I was particularly, bad slowing down consderably just before mile 50. There are a few more factors to consider but the fact that my shifting was all off plus I didn't feel any stronger has led me to believe I'm neglecting something.

Any thoughts/advice (no getting rid of the roadbike is not an option).
