Charlie Glotzbach with 1968 Dodge Charger.

One of NASCAR's records unlikely to be broken belongs to Charlie Glotzbach, who won the 1971 Volunteer 500 at what is now Bristol Motor Speedway. By today's standards, running a race at Bristol - or anywhere else for that matter - would be considered unimaginable. That's what happened at Bristol on July 11, 1971, when Glotzbach, in a Chevrolet, won by three laps over Bobby Allison, and averaged a record 101.074 mph, one of only two races (the other was won by Cale Yarborough in 1977) ever run at Bristol at an average speed of 100 mph or higher.
