The Glidden Tours, also known as the National Reliability Runs, were promotional events held during the automotive Brass Era by the American Automobile Association (AAA) and organized by the group's chairman, Augustus Post. The AAA, a proponent for safer roads, acceptance of the automobile and automotive-friendly legislation, started the tour to promote public acceptance and bring awareness of their goals.[1]
The original Glidden Tours were held from 1904[2] until 1913. They were named after Charles J. Glidden, a financier and automobile enthusiast, who presented the AAA with a trophy first awarded to the winner of the 1905 tour.
In 1906, the Glidden Tours were the first motor race to use a checkered flag to indicate the end of the race: Sidney Walden divided the courses into sections; the time check at the end of each section was performed by race officials called "checkers." These checkers used checkered flags to identify themselves.[3]
The first two days of the 1907 edition of the Glidden Auto Tour were marred by a number of accidents that resulted in the death of one man, Thomas J. Clark, lifelong friend and partner of John K. Stewart, and four other persons severely injured. While trying to make a sharp angle in the road preparatory to crossing a bridge, about two miles east of Bryan, Ohio, Mr. Clark lost control of his Packard that jumped over an embankment. The car turned over and he was crushed between the steering wheel, suffering several ribs broken and serious internal injuries, from which he succumbed four days later at Bryan hospital. It is believed that Mr. Clark was demonstrating the Stewart speedometer on the 1907 Glidden Auto Tour.[4]
At the turn of the century automobile travel was difficult as the road systems around the world were generally not well suited for the horseless carriage.
To bring more awareness and sponsorship to the event, the AAA announced that the tour would be a "reliability and endurance" tour, a type of road rally. This attracted automobile manufacturers who competed to test their vehicles and use the events for advertising.
The tours were gruelling events: cars broke down, were damaged by accidents, and encountered nearly impassable roads. Drivers and teams did repairs on the run and helped out other drivers having difficulties.
The tours went several hundred miles in the US and occasionally into Canada with time limits between check points and a point scoring system to determine a winner of each event. The time limits caused some problems with the inhabitants of where the tour traveled through as autos scared horses, caused personal and property damage and sometimes appeared to not care.
