100 mph Club

The first driver to complete the Indianapolis 500 at an average speed of 100 mph was Pete DePaolo in 1925. However, Norman Batten drove 21 laps of relief (laps 106–127) while DePaolo had his hands bandaged due to blisters and bruises. Thus DePaolo did not accomplish the feat solo.

Five years later in 1930, Billy Arnold won the race with an average speed of 100.488 mph. He was the second driver to complete the race in under five hours, but the first ever to do so without relief help.

In 1934, M.C. deWitt, the advertising manager for Champion, had a conversation with driver Dave Evans. Evans had finished 6th in the 1934 Indianapolis 500. In doing so, Evans had become the twelfth driver in history to complete the full 500 miles solo, at an average speed of over 100 mph. Immediately deWitt envisioned an idea to create an honorary "club" for the drivers who had accomplished the noteworthy feat. In 1935, the Champion Spark Plugs 100 mph Club was born.

The inaugural class would consist of the 12 drivers who had accomplished the feat thus far. The first member retroactively being Billy Arnold, along with Fred Frame, Howdy Wilcox II, Cliff Bergere, Bob Carey, Russ Snowberger, Louis Meyer, Chet Gardner, Wilbur Shaw, Lou Moore, Stubby Stubblefield, and Dave Evans. An annual banquet would be held in the drivers' honor, and each inductee would receive a leather jacket. Carey and Stubblefield were deceased, and Arnold did not attend, but all of the other nine living members were present at the first banquet.

The requirements to qualify for the 100 mph Club were fairly straightforward. A driver was required to complete the Indianapolis 500 at an average speed of 100 mph or faster, driving the entire race without any relief help. It was permissible to be accompanied by a riding mechanic. However, the period in which riding mechanics were utilized at Indianapolis overlapped only briefly from when the club was formed.

The 100 mph average speed equated to finishing the race in five hours or less. The driver was not required to win the race, but a strict requirement was to complete the full 500 miles (200 laps). Rain-shortened races, or drivers that were flagged off the track before completing all 200 laps (even if their average speed was over 100 mph at the time) would not qualify.

Drivers were inducted for lifetime memberships, but drivers were separately honored each time they accomplished the feat. Many drivers broke the 100 mph barrier multiple times during the career. Ted Horn accomplished the feat a record total of eight times in his career. Each subsequent membership was rewarded with being seated at the head table during the next annual banquet.

Prior to the 1960s, the drivers were permitted ample time to complete the full 500 mile distance, even if it meant remaining on the track for several minutes or over an hour after the winner crossed the finish line. In the very early years, completing the full 500 miles was even a requirement to receive any prize money. For a time, it was the norm for officials to wait until at least 10-12 cars completed the 500 miles before waving the cars off the track. However, that was not a hard-and-fast rule. Officials often just used judgement to decide when it prudent to stop. A total of 16 cars went the distance in 1959, while only five did so in 1938. In 1940, only the top three were permitted to finish, due to a rain shower.

The honor of joining the prestigious 100 mph Club was considered motivation to continue racing, even if the chance to win the race had already gone away. In most cases, several cars would complete the distance, and numerous drivers might be added to the Club annually.

Around 1954, Champion formed as part of their public relations efforts, a Driver's education program geared towards teenagers and young adults. The Champion Highway Safety Program traveled around the country giving presentations at high schools and military bases about driving safety tips. For many years, a team of drivers from the 100 mph Club were used to give the lectures, and some were used in Educational films.[1][2]

The lectures were popular and well-received, and were usually sponsored by a local newspaper or radio station.[3] The appearances were also used as promotional tool for automobile racing, and offered the drivers work during the off-season.

In 1964, when the race started airing live on MCA closed-circuit television, the rules were changed which limited the time drivers were allotted to finish the race once the winner crossed the finish line. Roughly five minutes were allowed for the other cars on the track to complete the 200 laps. This had the effect of substantially limiting the chances of joining the 100 mph Club, and only a handful of drivers earned the honor after 1964.

Also perhaps contributing to the club's demise was the evolving times. By the mid-1960s, speeds at Indy had risen considerably since the club's formation - and were poised to rise substantially over the next few years. Covering the full 500 miles at an average speed of 100 mph was nay considered a noteworthy accomplishment any longer. Most winners were finishing the race with as much as an hour and a half to spare to fulfill the 100 mph Club's qualifications. Apropos to that, membership in the drivers' eyes was still highly coveted.

In 1964, Autolite created the "Pacemakers Club," which recognized drivers who had led at least one lap during the race. It began to rise in stature and popularity, and became a more period-relevant "club," associated with the Indianapolis 500. In its favor, it was not linked to changes in equipment, conditions, or perceived obsolete speed milestones.

During the 1969 race, no new members were inducted into the 100 mph Club, since all four drivers who completed the 500 miles that year were already part of the club. In 1970, Dick McGeorge, Champion's public relations representative, retired from his position. McGeorge was considered the key fixture in organizing the club, dating back to 1946. He died in 1971, and the 100 mph Club quietly folded. In retrospect, the 1968 inductees (led by race winner Bobby Unser) would be the final names added to the membership.

Membership list as of June 1, 1968[5]

From 1970 to 2016, a total of 108 additional drivers have unofficially joined the 100 mph Club. Although no official subcategories have ever been created, a total of 98 of them made it into a faster "150 mph Club."

A total of 33 drivers have joined the very exclusive "185 mph Club". They are led by Tony Kanaan, who won the fastest 500 in 2013. Two additional drivers, Rick Mears and Michael Andretti, managed to break the 175 mph barrier from the 1991 race.

During the late 1980s and early 1990s, a separate award was created called the Marlboro 500 Mile Club. Sponsored by Marlboro, it was a cash prize of $75,000 split amongst the drivers who completed the full 500 miles each year.
