Awesome ride! Just warm enough for shorts and a T-shirt, but not hot enough to sweat. Riding on newly inflated tires (they were at 60 psi before!! ughughugh) made all the difference. Also, these new Specialized Body Geometry gloves are pretty nice, they seem to actually work. I climed that second, largest hill at a relatively (for me) fast 14 km/h.
I'd been off my bike since wednesday when I took a bit of a tumble and scraped up my elbow, but I've got a gruesome scab to show off at work now.
