Average speed for the front runners in the Tour de France on an average stage is usually around 25mph, and that's with some gruesome hill climbs. On the faster stages, average speeds can reach 35mph. Sprints often hit 40mph, and on downhill stretches are known to exceed 60mph. I commute 7.5 miles into central London daily where the roads really were originally built around the horse and cart and usually manage ~22mph average if the traffic isn't so bad and I catch the lights right.
