The 2020 Tour de France could feature two unprecedented summit finishes as details of possible stages in the Alps and Jura were revealed this week.

The full route for the 107th edition of La Grande Boucle will be announced in Paris on October 15, but local newspapers report that summit finishes are planned for the Col de la Rose and Grand Colombier in the final week.

The Dauphiné Libéré, which covers the area surrounding the Alps, reports that the Col de la Rose, a newly built traffic-free high-altitude pass between Courchevel and Meribel, will feature as the final climb of stage 16.

Previously, it was possible to ride or drive to Altiport, above Meribel and Courchevel, but not to the top of the mountain. Now the local authorities have paved a 6-kilometer track on both sides for cyclists. At 2,304 meters above sea level, it is the seventh highest col in France.

The Col de la Rosé was used in the Tour de l'Avenir in August for a short stage from the valley of Brides-les-Bains to the summit. The climb, which has an average gradient of 7.7% and is 23 km long, will reportedly be used in stage 16. According to the Dauphiné Libéré, the stage will start in Grenoble and pass through other passes (such as the Madeleine Pass) on its way to the Rozé.

The climb from Bride-les-Bains to the ski resort of Meribel was used in the 2016 Criterium du Dauphiné, where Thibaut Pinot won the stage. The 4km climb to Altipole was last used in 1973 when Meribel finished the Tour, won by Bernard Thevenet.

The stage, rumored for 2020, will be an additional 6 km on a newly paved cycling track just over 4 meters wide. The average gradient is close to 10 percent, with several slopes exceeding double digits. Breaking the 2,000-meter-high wall will make for a great day for pure climbers.

The Rhône-Alpes newspaper Le Progrès reports that the Grand Colombier will be included in the finish. This 1,500-meter-high mountain in the Jura Mountains, not the Alps, is familiar to the Tour but has never been used as a summit finish.

There are at least four roads to the summit, but Le Progrès does not mention which one is used: in 2017, the hardest road, 8.5 km or 9.9% from Villeux-le-Petit, was used in the middle of the stage to Chambéry, won by Rigobert Urán; 2016, Grand Colombier was used twice in the finale. First from Rocheux (12.8 km, 6.8%) and then from Culoz up the "Racetes" (8.4 km, 7.6%). In that case, the riders turned around at the top of the Racetes and descended to Curroz, where Jarlinson Pantano beat Rafal Mayka, but in 2012 the path continued to the summit, where Thomas Voeckler won solo in Bellegarde.

According to Le Progrès, the Grand Colombier stage will likely take place on stage 18 on July 16. The final stage is strongly rumored to be a transition stage from the Jura mountains to the Vosges mountains, with La Planche des Belle Filles (possibly a time trial).

It has already been confirmed that the race will start in Nice in southwestern France and will include both flat and mountain stages. After that, reports and rumors have been that the race will visit the Pyrenees Mountains on the second weekend before the first rest day, then head north and then east across the Massif Central to the Alps.
