Speed Walkers gone mad!

Okay, the other night, I overheard some guys laughing about speedwalking being an olympic sport, and I laughed along, agreeing that I wasn't sure it was olympic worthy. I thought they were kidding, and then, last night, what comes on the Olympics? Speedwalking! It's real! And it is quite funny to watch. I'm not, in any way, saying this isn't a sport, but some of the events in the Olympics are questionable. Trap shooting, ping pong, doubles ping pong... ???
