Gabriel Poix started his international rowing career on the stroke of the French inriggers’ coxed fours at the 1912 Olympic in Stockholm. At the 1913 European Championships he won the title in the coxed pairs with Maurice Monney-Bouton and Ernest Barberolle as coxswain. After the break during World War I, the boat returned to the Europeans in 1920 repeating the victory. France came to the Olympics in 1920 with the same crew. Two weeks later, Poix, Monney-Boutin and Barberolle won silver at the Olympics in Antwerpen. There, they were beaten by the Italian boat that did not compete at the Europeans.
