Cyclist Alwin Boldt finished the 20 km and the 100 km track races at the 1908 London Olympics with unknown results. He was also eliminated in the tandem sprint alongside [Max Triebsch]. Boldt competed for BBC Germania Berlin. He was an engineer by profession. Boldt stopped racing between 1901 and 1904 in order to finish his studies. He then participated in motorcycle races both on the road and paths beginning in 1905. Boldt then set a German record with 3 hours 10 minutes and 220 km on the Bremen-Hamburg-Bremen circuit. He also won the 50 km German Championships that year as a pace follower, and claimed the title with [Hermann Martens] in the tandem, repeating this title in 1907 at Leipzig.
