WILLIAM CAMPBELL had been in a pursuit race with a burlesque show ever since Pittsburgh. In a pursuit race, in bicycle racing, riders start at equal intervals to ride after one another. They ride very fast because the race is usually limited to a short distance and if they slow their riding another rider who maintains his pace will make up the space that separated them equally at the start. As soon as a rider is caught and passed he is out of the race and must get down from his bicycle and leave the track. If none of the riders are caught the winner of the race is the one who has gained the most distance.
