Found my way down to the Pleasanton Ridge trails and ran to the first crest. Fooled around a bit on the trails and by the time I got home I was really ragged! Now my whole body is completely spent and I'm going to spend the evening recovering.
Foothill loop. My quad felt really really tight, but loosened up slightly near the end. Hopefully this is just some kind of residual soreness from being cramped in the car for 2 days.
