Col du Glandon has been included in the Tour de France 13 times since it was first introduced in 1947.  After its inaugural year, Glandon was not included again until 1977, and has been included sparingly thereafter (averaging about once every four years, 11 times in the 43 years between 1977 and 2020).  As of 2020, the last time Glandon had been included in the Tour was 2013.

Merckx realized his mortality on Glandon, Stage 18 1977 TdF.

The king of Col du Glandon is unquestionably Lucien Van Impe (winner 1976 Tour de France).  Van Impe participated in each TdF from 1969 to 1981 and Glandon was featured in three of those tours (1977, 1981, and 1983).  Van Impe was first across the col on each of those stages, on his way to winning the mountain classification each time.

Col du Glandon was the prologue to one of the most famous (or rather, infamous?) cycling moments of all time.  Col du Glandon was the middle climb of three on Stage 10 July 17, 2001 (Col dd Madeleine, Col du Glandon, Alpe d’Huez).  Lance Armstrong had dropped from 5:56 back after Stage 7 to 35:43 back after a disastrous Stage 8 which saw a freak breakaway won by Erik Dekker, Alto Gonzalez and Servais Knaven. Armstrong was 20:07 back after Stage 9 and his main rival that year, Jan Ullrich, was at 22:41 going into Stage 10.

Armstrong appeared weak on Col de Madeleine which led Ullrich and his Team Telekom to begin an insane sprint up Col du Glandon, leaving Armstrong barely(?) hanging on to the rear of this lead group.  However, just a couple kilometers up Alpe d’Huez and with 11 kilometers remaining, Armstrong surged to the front of the group past Ullrich and then, in a moment of Tour lore, looked back (“The Look”) at Ullrich, fixed his gaze on him momentarily, then put the hammer down and accelerated away from a broken Jan Ullrich to victory and his third Tour de France victory of 7.[1]
