The idea of running against a speed patrol station has intrigued me for years. One magically appeared in my neighborhood this past week. I’m willing to bet this isn’t entirely accurate, but it’s probably reasonable. For comparison (and embarrassment) World Class runner, Usain Bolt, runs an estimated top speed of 30 mph in the 100-meter-dash, and an average of 23.5 mph. I’m no slouch, and I’m running at 70% of my top speed. Based on this machine I might get to 20 mph at my top speed. Usain Bolt is wickedly fast. And this was as fun as I thought it would be.
