The col was used for the first time on Stage 10 of the 2014 Tour de France, when the leader over the summit was the Spanish rider, Joaquim Rodríguez.[6] The col was used again on Stage 20 of the 2023 Tour de France. The leader over the summit was the French rider Thibaut Pinot. During that stage, the top of the climb became known as the "virage pinot" (Pinot's corner). Pinot's fans gathered at the summit to cheer the rider during the last Tour de France mountain stage of his career.[7]
