There was a good piece on Marketplace last evening about the challenges facing the sport of cycling. Following several years of struggling over drug usage a number of key sponsors are now on hard times financially and are pulling sponsorships. Later this year the U.S. Postal Service, who sponsors the team Lance Armstrong rides for, will end their sponsorship. The news follows on Saturn's decision to leave the sport as well. Meanwhile Armstrong will attempt a record-setting sixth win in the Tour De France next month.
