A big guy passed me on the way home lumbering along at 20mph and low cadence. I was doing 18mph and 95RPMs....we get to a large hill. No lie this guy climbs the whole thing (about .5mi out of the saddle). I kept right up seated and as he faultered, I passed him and stayed ahead the rest of the route.

Never seen such a big guy, move so effortlessly, low cadence high gear, high speed.
