Usain Bolt, who holds the world record for the 100 meter dash can run 23 miles per hour. Last night while biking home from work I decided to see if I could match his speed (on my bike). There is a stretch of straight road with no traffic that is about 300 meters long between Ivy and Fir street. From a complete stop I hammered my bike as fast as I could get it, I hit top gear and pedaled until my legs ached. I hit 21.1 miles per hour.
