Some of us MTBers have massive quads. Only time I've ever seen a woman going that fast around here though, she was a kitted roadie. (Roadess?)

55F for me this morning. Sunny. Light tailwind. Quite a few cyclists out and about. I passed 4 or 5. I think one was behind me but it didn't get close enough to verify. Several pretty young women out running, too.

Oh and the neighborhood wild turkeys were out wandering around when I left for work. They just froze and stared at me as I passed them.
