Bike to work weak

My quads are killing me. I bicycled to and from work each day this week to mark my 10th year of participation in Bike to Work Week. I prefaced the week of commuting with a fast Sunday ride at Sweetwater, so I started out a bit fatigued. The first afternoon headwinds of spring made a couple of the days harder than others. This year, with the City of Tucson being just about broke, the BTWW events were dispersed amongst local businesses. No big event at the library and no schwag for me.
