Jim Borthwick was born September 14, 1942 in the State of Maine. He moved to Delaware with his family and began his racing career at the age of 16. Jim was one of the original members of the Blackbird Micro-Midget Racing Club and was presented with a lifetime membership in 1983 honoring his many years of service to the Club. Throughout his racing career, he was credited with 59 Feature wins, 13 of which were recorded in the same year. He also won at least 1 Feature Event for 11 straight years. Jim was Class Point Champion in 1966, 1968 and 1970. In his final year with the Club, he posted 4 wins and 4 second place finishes in the Industrial Flathead (IF) Class driving the familiar #77. He was leading the Class point race in 1984 at the time of the on-track accident which took his life. Jim passed away on September 24, 1984 as a result of severe head injuries. In Jim's honor, the 4-stroke Division, each year, lines up their Feature event with the pole position open and concludes their race on the White Flag lap at which time they pull into the infield signifying that the race never ends.
