I too have a similar story of a gray-haired guy who rode hard. I was coming back from a ride to the beach when I saw an older gent turning onto the same highway with me. He was on a hot carbon bike and I thought I'd leave him in the dust. I ended up riding the last 15 miles of my ride at a hard pace only to turn on my block with him still a few bike lengths behind me. He then rode by and effortlessly said "good riding" and I said "yes, thanks" while trying to mask my heavy breathing.
