None of us mere mortals will ever make a dent in those climbs ridden by pros, retired pros like Cookie Man and serious amateurs. I'd be satisfied if I finished those in less than 30 minutes. I'm not much of a climber.
I only compare my Strava times with a few friends who are around the same age and comparable in fitness, speed, etc. Mostly I compare with my own previous times. Anything else is unrealistic.
I've had a few top tens, second on a couple of segments, but I've lost most of those as some fast group rides have blown through. Realistically, a guy my age should never have a KOM or even a top ten on any Strava segment ridden by enough people. If a 63 year old has a KOM or top ten, it means either nobody rides that segment, or, if it's a popular segment, I'm doped to the gills.
