Craig joined me for another week day ride and, for my birthday, consented to push himself on some gratuitous hills, some of which were at 14 and even 17%. I think, though, that there is still room to embellish this route significantly if I study the map a bit. As it was, I felt a sharp pain in the front of my right knee, which I attribute to an aggravation of my meniscal tear from pushing hard while climbing in a sitting position on the single speed yesterday. The pain was most acute when standing out of the saddle at the top of the spinning cycle, but the pain decreased over the course of the ride, and I only felt a slight twinge when I started to apply a lot of torque at a low cadence while sitting on the way up Foothill towards Lowell.
