The Women's Challengebicycle race was held annually in the westernUnited States in southern Idaho, beginning in 1984 until its demise in 2002. Later primary sponsors were PowerBar and Hewlett-Packard. During much of its 19-year history, it was the most prestigious women's cycle race in North America. From 1995, when it first obtained sanctioning from the Union Cycliste Internationale, the internationalgoverning body for cycling, it developed into one of the strongest races in the world, attracting numerous World and Olympic Champions. Prior to that, in 1990, the UCI had refused to sanction the event, citing as their reason the "excessive climbing, stage distances, number of stages, and duration of event." The race that year, Idaho's centennial, began in northern Idaho at Sandpoint, was 17 stages and, and was won by Inga Thompson. The fifth stage through Lewiston ended with the climb up the Spiral Highway, a vertical rise of. The following year marked the debut on the international scene of a team representing Lithuania, which had just recently declared its independence and was still awaiting recognition as a country. Professionals were allowed to compete beginning in 1993. The race, which was run almost entirely by volunteers, set a very high standard in terms of technical administration and conduct of the race itself. Jim Rabdau, the race founder, served as chief organizer of the race throughout its entire history. By the late 1990s, the race was able to attract sufficient sponsorship money to offer the richestprize fund ever in women's cycling and, for a while, was the richest prize fund race in North America, men's or women's. At its peak, it offered $125,000 in prizes. However, cuts in sponsorship forced a reduction in prize money to $75,000 in its last year and no title sponsor could be found to replace the outgoing sponsor for the following year, forcing the cancellation of the race. Race organizers cited a downturn in the economy as the reason. One of the stages crested Galena Summit at above sea level on Highway 75, the Northwest's highest highway pass.
