When I first spotted the picture below on Jalopnik I thought to myself “I need to know the story behind this picture.†As it turns out, there’s some interesting history and I learned about a sport that’s new to me, motor-pacing.
150 mph is fast, in any car, Porsche or not. Imagine how fast it must be on a bicycle? That was the speed Jean Claude Rude was trying to reach in his attempt to break the world bicycle speed record in 1979 (that’s him in the picture above holding on to the bike)  … Details & Pictures
