Today, while out riding, I realized that in 10+ years I've rarely passed a road cyclist who wasn't broken down, but I'm passed multiple times every time I go out. Funny thing is, it never bothers me.
The best drop I ever experienced was going up Ortega Hill in Summerland, CA last year. It's short and pretty steep, and it's also the turn around point for my centuries, so I was already into it 50 miles that day. As I was chugging along in my granny ring at maybe 8 mph, a young, very good looking woman passed me like she was gliding along a flat section with a 25 knot tail wind. As she went past she slowed for maybe 10 seconds, looked me right in the eye, told me I was doing great, and to just keep spinning. Then off she went.
