The first documented deaths of professional cyclists during competition date to the 1890s. Before 1929 at least 47 professional riders and pacemakers[Note 1] died at velodromes in track cycling[1][Note 2] and since 1994 a number of professionals have been killed in accidents with motorized vehicles while training on public roads. The dangers of cycling continue to be disputed among modern sources. For example, the 2005 United States Consumer Products Safety Commission (CPSC) data showed bicycling to be nearly as dangerous as American football.[2] A survey of 2008 Olympics teams, however, indicated that cycling was not even in the top 6 most injury-prone sports during competition that year.[3]
