The Red Zinger Bicycle Classic (1975–1979) was a road bicycle racing stage race.
In 1975, Mo Siegel and John and Wyck Hay, founders of the Celestial Seasonings herbal tea company, launched the Red Zinger Bicycle Classic race to promote alternative transportation in the Greater Boulder area, particularly bike lanes, bike paths, and community awareness. The Classic was named after their popular Red Zinger tea.
In 1979, Michael Aisner, the race's then PR director, bought the race for one dollar from Siegel, and with his blessing took the idea of a grander event to Peter Coors, the beer impresario. Over the next 8 years, the Coors International Bicycle Classic grew into two weeks of racing in California, Nevada and Colorado, with stages in some years in Hawaii and Wyoming.
From 1981-1992 a youth bicycling series called the Red Zinger Mini Classics was held in Colorado, its name inspired by the original Red Zinger Bicycle Classic, inspiring a generation of young cyclists to enter the sport.
