In between, other things went on at the raceway including motorcycle road racing, sports car racing (1972) and one of the first skateboard parks (1976) ever built in the United States. More WWOS TV came with the addition of the“Superbikers” event 1979 that was the forefront to modern Supermoto racing we know today.
But the motocross world shifted in 1980 when San Diego localand privateer rider, Marty Moates became the first American to in the USGP after the race being dominated by European riders, namely Dutch rider Gerrit Wolsink who won it an astonishingly five times. Another San Diego local, ElCajon’s Ricky Johnson would win the last USGP in 1986.
Due to the rising value and need of north San Diego county real estate for development, sadly the property of the Carlsbad Raceway would be sold. The final drag race was in August of 2004 and the raceway finally closed in 2006.
