On yesterday's club ride, I paced myself in the first 20 miles, mainly due to the heat and humidity. At one point I judged the gap to be 45 seconds or so. Eventually they slowed and I reeled them in.
In the middle of the ride was one big monster hill. I easily cruised to the top, dropping everyone else, and waited for the rest under a shade tree.
And I was in my 50+ summer-weight jersey.
That's a cool story. Reminds me to start wearing my 50+ jersey more, especially on the Saturday morning shop rides.
