I want to draw your attention to the recent news about one of the greats in cycling history - Gino Bartali, triple winner of the Giro (1936, 1937, 1946), two-time winner of the Tour (1938,1948) and with multiple victories of La Primavera and Il Lombardia to his palmares.
Gino Bartali, who died in 2000, was a few days ago declared a "Righteous Among the Nations", by the Yad Vashem Holocaust memorial. This is a posthumous recognition of Gino’s activities as a courier for the anti-fascist resistance during the German occupation of Italy. Transporting forged documents hidden in his handlebar and saddle during his extensive "training rides" he helped to rescue Jews from prosecution. Allegedly he also hid refugees in his cellar and led Jewish refugees towards the Swiss Alps himself.
He never publicly mentioned his activities during WW2, and the extent of it came to light only after his death. When asked about it he said: "Good is something you do, not something you talk about. Some medals are pinned to your soul, not to your jacket."
