A second rider has tested positive for the blood doping drug, EPO at this year's Tour de France. I'm glad I have not wasted my time with this year's race. This time the racer is Moises Duenas Nevado with the Barloworld team. Additionally, the French police found additional banned substances in his hotel room after the positive test results. The team has indicated that these substances were not provided or prescribed by the team or team doctor.

The first rider tossed out of the race was Manuel Beltran after testing positive for EPO after the first stage. EPO is a shortened version of the term erythropoietin, a hormone that increases red blood cell production, thereby increasing oxygenation of the cells. This especially helps the riders in the low oxygen conditions of the mountain stages during the race.

Blood doping and performance enhancing methods continue to plague the Tour and professional cycling, in general. Professional cyclists are perhaps the most tested of any athletes. In spite of all the testing, riders continue to try to beat the system and get by with cheating. If this is the case in professional cycling, the most tested sport, imagine how bad the cheating problem could be in other un-tested professional sports.
