Road cycling is popular enough among so many healthy folks in my area -- including more gals than I ever saw 20 years ago-- that, I'm definitely at the slow end of the curve, but... to anyone going the other way, I probably look good. When I start out, if no one is closer than a mile behind and I'm doing ~12 mph, they'd be going 16 mph to catch me up in 3 miles and if they blow by I'll probably never see'm again because I've never done my regular run faster than an avg. of 13 mph. So, I'm never competing against anyone but myself.
