1975 Long Beach Grand Prix
The 1975 Long Beach Grand Prix was the inaugural running of the Grand Prix of Long Beach. The race was held September 28, 1975, on a  temporary street circuit. It was race 7 of the 1975 SCCA/USAC Formula 5000 Championship. An estimated 65,000 spectators saw Englishman Brian Redman win the race from Australian Vern Schuppan, with Canadian driver Eppie Wietzes finishing third. Background
In 1974 the city of Long Beach began a billion-dollar redevelopment program of the downtown area. Chris Pook, a British travel agent working in Long Beach, proposed holding a street course race in the vein of the Monaco Grand Prix. In order to prepare for a Formula One race the following year, the organizers decided to hold a Formula 5000 race that was held at a track in Riverside with an exhibition in Long Beach. Qualifying
Qualifying times were set in two sessions on Saturday. Seeded drivers had one 45-minute session and one 1 hour, 15 minute session, while non-seeded drivers had two 45-minute sessions. Starting positions were set by two heat races, with the finishers from Heat 1 starting in odd positions and Heat 2 in even positions. Heat races
