So far so good - I've managed 2 bike and 2 bus commute's this week. That brings the bike total up to 60miles, and yes, I am feeling it :-)
Best bit is knowing that every car that passes you at the top of Avondale will be stuck in the traffic that you wizz through at the bottom. Worst bit is the way that the real pro's cycle past you as if you where standing still on the 520 trial.
