Some years ago I was briefly acquainted with a 30-ish gentleman who was a "Race Walker". I have always been what I call an "Exercise Walker". I don't run, but I walk fast and have completed a bunch of events. He had won some Race Walking races and taught me the basics. One foot must remain on the ground at all times. Doing so gives the walker an odd gait and looks kinda funny. It wasn't for me, and I didn't pursue it as an activity.
But, I do love those rare occasions when I can watch televised Race Walking events, as with the Olympics. So, of all the events being held in Paris, my favorites have been the Men's and Women's Race Walking.
