I occasionally see other cyclists on my commute, but rarely going the same direction, and can't remember the last time I was passed. Today 2 roadies caught up to me and passed me at the top of a hill just before a stop sign. They looked fast. I said to the second one, "I might have to draft you guys."
He said, "Yeah," in a tone that I felt he was implying, "That would be good for you, but I doubt you will keep up."
I had to work a little to stay with them and worked up a bit of a sweat. But the next 2.5 miles they (we) rode at 25mph, much faster than my normal 18-20mph for that section. They were glancing back to see if I was still there a couple of times. At the next stop sign they were going a different direction. I said, "Thanks guys, have a good one." One replied, "You too," and that was it.
