The queen stage of the 2026 Tour de France: Galibier and Alpe d'Huez on the penultimate day

The finale of the 2026 Tour de France promises to be another gruelling challenge and a new terrain. For the first time, the route to Alpe d’Huez will not take the legendary 21 hairpin bends, but will instead go via the Col de Sarenne – a route that was used solely as a descent in 2013 and will now serve as the ultimate test before the finale in Paris. After the Croix de Fer, the Col du Télégraphe and the ‘Roof of the Tour’ at the Galibier, the 20th stage presents uncharted territory with the Sarenne climb, where Tour history is set to be made. It’s important not to get confused, as Alpe d’Huez features twice on this year’s route. The famous 21 bends to Alpe d’Huez feature on the 19th stage – the 20th uses the lesser-known climb through the Ecrins National Park. This has sparked debate in the run-up to the race, as the natural environment there is particularly sensitive.

5,450 metres of elevation gain: a whole new dimension

Stage 20 of the 2026 Tour, from Le Bourg d'Oisans to Alpe d'Huez, redefines what a queen stage can mean. With 5,450 metres of climbing over 171 kilometres, this mountain finish surpasses all previous records in the history of the Tour. Its strategic placement on the penultimate day of the Tour makes this stage a potential turning point, one that could lead to even more dramatic shifts in the general classification than the classic Gap-Alpe d’Huez stages with ‘only’ 3,500 metres of climbing. The sequence of climbs reads like a nightmare for any climber: the Col de la Croix de Fer (2,067m), with its 24 kilometres at an average gradient of 5.2%, is merely the opening act. This is followed by the Col du Télégraphe (1,566m) over 11.9 kilometres at 7.1% and the majestic Col du Galibier (2,642m), which, as a tribute to Henri Desgrange, marks the roof of the Tour with 17.7 kilometres at 6.9%. But the real unknown awaits at the end: the Col de Sarenne, 12.8 kilometres long with a 7.3% gradient – a mountain that was only ridden downhill in 2013 and now becomes the final test.

Sarenne: Alpe d’Huez via the back route

"Terrain vierge, histoire à construire" – uncharted territory where history can be made. These words from Tour organiser Christian Prudhomme capture the significance of the Sarenne route. In 2013, the riders used this pass solely as a descent following a dramatic change in the weather. The technical data for the Col de Sarenne reveal a climb that differs significantly from the traditional route. Whilst the classic ascent via the famous hairpin bends measures 13.8 kilometres at an average gradient of 8.1%, the Sarenne initially appears more moderate at 12.8 kilometres and 7.3%. But these figures mask the true difficulty: after four mountain climbs of the highest categories already completed, even moderate gradients become insurmountable obstacles. The highest point at 1,999 metres also leads into a short descent before the final stretch climbs to the ski station at 1,850 metres – a tactical element that will require entirely new strategies.

Alpe d'Huez: From Dutch dominance to the international stage

The history of Alpe d'Huez as a stage finish began in 1952 with Fausto Coppi, who became the first rider to win the Yellow Jersey at a mountain finish in a ski resort. What Coppi started, the Dutch perfected in the decades that followed: Joop Zoetemelk, Hennie Kuiper and Peter Winnen left such a lasting mark on the ‘Mountain of the Dutch’ that this nickname has endured to this day. However, the Italian renaissance led by Gianni Bugno and Marco Pantani in the 1990s showed that Alpe d’Huez would not remain a national domain. The 21st century brought a remarkable French renaissance: Pierre Rolland (2011), Christophe Riblon (2013) and Thibaut Pinot (2015) provided unforgettable moments in front of a home crowd. Riblon’s triumph in 2013 was particularly remarkable, as it had already taken riders over the Col de Sarenne – albeit in the opposite direction. The recent past has seen a British takeover: Geraint Thomas (2018) and Tom Pidcock (2022) celebrated on the mountain. With its 33rd appearance as a stage finish, Alpe d’Huez holds the all-time record in Tour history.

Tactical aspects: Alpe d’Huez twice

Scheduling the toughest mountain stage on the penultimate day of the Tour is intended to keep the tension high right until the end. With the mountain stage ending at Alpe d’Huez the day before, another gruelling test is in store for the 20th stage. Even seemingly comfortable leads in the general classification can be wiped out in a single day. A comparison with the classic Gap-Alpe d’Huez stages highlights the danger: whilst the 128 kilometres from Gap, with 3,500 metres of climbing, were already considered a queen stage, the new route exceeds these figures by more than 60 per cent. This increase is significant not only in quantitative but also in qualitative terms: the additional 2,100 metres of climbing alter the entire race dynamic and make surprises more likely.

Food strategy

The extreme demands of the stage pose challenges not only for the riders but also for their equipment. A 5,450-metre climb means over five hours of intense strain on both man and machine. Nutrition strategy becomes a decisive factor: energy expenditure of over 6,000 kilocalories requires a perfectly balanced supply that must not, at the same time, overload the digestive system. Teams will position their support staff at strategic points, although the new Sarenne route presents logistical challenges as the usual supply points on the classic route are not available.

Weather risks: When four climate zones meet

The route from Le Bourg d'Oisans to Alpe d'Huez via the Col de Sarenne passes through four different climate zones and altitude levels, which increases the risk of adverse weather conditions. Whilst summer weather may still prevail in the valley, snowfall is possible on the Galibier at 2,642 metres even in July. The combination of extreme altitude and prolonged exertion is particularly gruelling: whilst a single climb usually remains passable even in poor conditions, over 5,450 metres of elevation gain, small changes in the weather can add up to significant differences between the groups of riders. A temperature drop of 15 degrees between the valley and the summit, combined with the physical cooling effect of five hours of exertion, can cause even top favourites to struggle. Cycling fans will no doubt still remember the difficulties faced by Jan Ullrich in the 1998 Tour de France. He had cut the sleeves off his rain jacket and was freezing when it rained. On top of that, he suffered a bonk, which ultimately dashed his chances of victory.
