Documented deaths of competitive cyclists date to when the safety bicycle was invented in the late 19th century. Cycling as transportation and as sport became more popular (including bicycle racing). Accidents on velodromes date back to cycling's early days and were sometimes fatal. Various health issues for competitive cyclists including performance-enhancing attempts and cardiac events have also been part of cycling's history. From the 1890s until the present era, at least 100 professional or competitive amateur cyclists have died during races – usually from accidents but sometimes from various health conditions – and in that same timeframe over 30 cyclists have died in accidents while training on open roads. Many of these cyclists are remembered in museums, and with roadside memorials, plaques, statues, and shrines. (Full list...)
