Race car drivers in a 1931 Buick Series 60 Racer drive on Main Street Santa Monica after completing the annual Hemmings Motor News Great Race on Sunday, June 28, 2015. The cross country vintage-car rally and race began on Saturday, June 20, in Kirkwood, Missouri. The 2,400-mile route travels along the original "Mother Road" sections of historic Route 66 and finished at the Santa Monica Pier on Sunday, June 28, 2015.
The Great Race is an antique, vintage, and collector car competitive controlled-speed endurance road rally on public highways. It is not a test of top speed. It is a test of a driver/navigator team’s ability to follow precise course instructions and the car’s (and team’s) ability to endure on a cross-country trip. The course instructions require the competing teams to drive at or below the posted speed limits at all times.
Each day the driver and navigator team receives a set of course instructions that indicate every turn, speed change, stop, and start that the team must make throughout the day (usually 220 to 250 such instructions per day). Along the course route there will be from 4 to 7 checkpoints recording the exact time that the team passes that point. The objective is to arrive at each checkpoint at the correct time, not the fastest. The score for each team is the result of the team’s ability to follow the designated course instructions precisely. Every second off the perfect time (early or late) at each checkpoint is a penalty point. This format is much more mentally demanding than a flat-out cross-country race. Also, GPS or computers are not permitted and odometers are taped over. This is a test of human mental agility and endurance as well as classic car endurance, rather than programming capability. The course avoids timed segments on interstate highways, opting instead for scenic local, county, and state highways whenever possible through some of the prettiest country in the United States.
