MADRID (Reuters) - American rider Chris Horner missed a random anti-doping test on Monday after Spanish Anti-Doping Agency officials came to the wrong hotel, the Vuelta champion's team said.
"The testers came to the team hotel, Horner was not there, he was in the hotel where his wife was staying," a RadioShack press officer said.
"It's mentioned in the whereabouts form, they got the wrong hotel. Horner had changed his hotel. It was the Spanish agency that came on behalf of USADA (the U.S. Anti-Doping Agency)."
Horner, who turns 42 next month, became the oldest Grand Tour champion and the first U.S. winner of the Tour of Spain when he sealed victory on Sunday for the biggest win of his 19-year career.
Riders must provide the anti-doping authorities with their whereabouts.
