Check out the mid-winter temperature gradient (purple line, which hits 81°F). The colder temps are in the shade/canyon, but still 60° F and above. Summer jersey riding in late January.
This is by far the best winter training in 30 years. But the hills are still brown like summer.
1/2 mile from home, my tire was slashed open in the same spot as a few months ago. Tubular or not the tire was toast. But a pinhole leak in the front tire was plugged nicely by Stan’s No Tubes; see my Tubular Tires and Punctures.
