The last time I sprinted for real was against "California trick cyclist David Steed" (see video below), in a mass pack sprint in the traditional Arizona season-opener in Marana, in 1977 as a new Senior III in the USCF, after its renaming from the ABLA. I won. Despite running me all the way across the road, he sportingly left me just enough room to get by, and I did. Later that spring I tore the cartilage in my right knee playing touch football, of all things, and that was the end of my real sprinting on a bicycle. I had a pretty good road sprint, and if power meters had existed in the '70s, no doubt I'd be bragging even more.

I was amazed to find David Steed in this video:

The last two times I sprinted on foot were both trying to hold on to animals. About ten years ago, I let go of Emma, one of our donkeys, and stayed upright, but about three years ago, I held on to Raina, our late Great Dane, and she pulled me right off my feet. I can sprint for short distances on my toes in a fleet manner, but I don't do heel-strike jogging or running anymore, with my hip replacements and dislocation history, I need low impact exercise, and cycling is perfect for me.
