Geraint Thomas became the first British winner at Alpe d’Huez on the occasion of the 30th finish in the ski resort of the Oisans. He’s also the first rider to win a road stage to Alpe d’Huez with the yellow jersey. He outsprinted Tom Dumoulin, Romain Bardet, Chris Froome and Mikel Landa to extend his lead in the overall ranking.
161 riders started stage 12 at Bourg-Saint-Maurice. One non-starter: last year’s runner up Rigoberto Uran (Education First). After a fast start in the Tarentaise valley, Warren Barguil (Fortuneo-Samsic) was the first climber in action up to the col de la Madeleine. A front group of 30 riders was formed up the hill and split several times. GC contenders Steven Kruijswijk (LottoNL-Jumbo), Ilnur Zakarin (Katusha-Alpecin) and Alejandro Valverde (Movistar) were part it, as well as KOM fighters Julian Alaphilippe (Quick Step), Serge Pauwels (Dimension Data) and Barguil. Alaphilippe smartly outsprinted his two rivals to extend his advantage.
