All the time. It's sort of a challenge. I caught one today even. Sometimes it's hopeless, though. I ride my mountain bike 2 miles to a coworkers house everyday and we commute from there. I remember once coming around the first corner and seeing a guy on a nice road bike probably 200 yards ahead. I basically sprinted the whole way home and doubt I gained an inch on him. Sure got me home fast.
