Adolphe Hélière (10 March 1891 – 14 July 1910) was a French cyclist that died during the 1910 Tour de France.
He died on a rest day after the sixth stage from Grenoble to Nice. He was reportedly stung by a jellyfish while bathing in the ocean near Nice, although his cause of death is unclear and may have been drowning due to exhaustion.[1][2][3]
While three men have died during the actual race, Hélière is often listed in the four total deaths.[4] He was 19 years old when he died.[5]
