Great day of riding for me in cool temperatures. TJ invited me to join him on the Acton Loop, plus a run up to the burned out Mt Gleason fire camp. TJ had a flat up there, but fixed it quite quickly. My R knee was barking to start with because of strain I put on it riding my single speed up Big T yesterday, but I had taken 800 mg of ibuprofen the night before, and it warmed up and felt pretty good after maybe 90 minutes, and I only felt a handful of twinges during the day, except for our spin down Soledad Canyon when we had such a great tailwind that I couldn't spin fast enough to take full advantage. Spinning at over 100 rpm at times was WAY more than my knees are used to and the R knee started to bark again until I eased up a bit, after which it was OK for the rest of the ride, even climbing Sand Canyon and Little T. With the cool temps, I had my best time climbing Angeles Forest Hwy from Upper Big T to Mill Creek Summit today, which was a very pleasant surprise considering how slow I have been all year this year. I could say my old form came back from retirement to make a surprise 1x appearance. ;-)
