Abstract

The 1990–2010 periods in professional cycling are labeled by some as the ‘epo epidemic.’ Surprisingly, performance enhancement of epo and blood doping is not that clear–cut for endurance athletes, leading to the question whether doping indeed strongly influenced cyclists’ performances from the 1990s onwards. We examined records (1947–2008) of the Tour de France, Giro d’Italia, and Vuelta a España (N = 181) and assessed the time it took riders to win the race. Findings revealed normally distributed performances and linear and quartic relationships in victors’ performances over time that correspond with Brewer’s (2002) socio–historical analysis of professional road racing, suggesting that effects of the epo epidemic on pro cyclists’ achievements may be overestimated.
