The 1926 Tour was the longest in its history (5,745 km), with 17 stages averaging 338 km. Buysse, racing with his two brothers Jules and Michel, took the yellow jersey from Gustave Van Slembrouck on stage 10 by attacking during a furious storm on the Col d'Aspin in the Pyrenees. He gained almost an hour during the stage over his team leader Bottecchia who then abandoned. Buysse arrived in Paris as the champion despite suffering the loss of his daughter during the race.
