Brad Andres of San Diego, California came back to Laconia, New Hampshire, and successfully defended his 100-Mile National Road Racing Championship. Performing brilliantly on his Harley-Davidson, he not only won the National title again from a strong field, but also set a great new course record of 1 hour, 43 minutes, 5.36 seconds. This new record smashes the old mark, also set by Brad in 1955, of 1 hour, 49 minutes, 46.36 seconds.
During the time trials, only two of the Class A riders circled the course in under 60 seconds. Brad Andres made it in 59.16 seconds and Joe Leonard, also on a Harley-Davidson, turned the course in 59.25 seconds. Another Harley-Davidson rider, Leon Applegate, was the only one in the 60-second bracket with 60.47 seconds. All eight events on the program were won by Harley-Davidson riders.
