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 3 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 (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 Uhllrich and his Team Telekom 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, passed Uhlrich and then, in a moment of Tour lore, looked back (“The Look”) at Uhlrich, fixed his gaze on him momentarily, then put the hammer down and accelerated away from a broken Jan Uhlich to victory and his 3rd Tour de France victory of 7.

 We all know, but it is necessary to mention here, that Lance Armstrong’s 7 tour victories were all stripped due to the use of PED’s.
