The Iditarod Trail Sled Dog Race first ran to Nome in 1973, after two short races on part of the Iditarod Trail in 1967 and 1969. The idea of having a race over the Iditarod Trail was conceived by the late Dorothy G. Page. In 1964, Page was chairman of the Wasilla-Knik Centennial and was working on projects to celebrate Alaska's Centennial Year in 1967.
