A scenic ride on the roads of the Tour de France

The Martigny region in Valais, Switzerland has become a go-to cycling destination. It hosted the Tour de France in 2009 in Verbier as well as in 2016 at the Emosson dam and it should have welcomed the 2020 Road World Championships with the neighboring city of Aigle, which houses the headquarters of the UCI. But then there was COVID...

Good news: you can ride on the roads of the Tour and the circuit of the worlds with the Petite Forclaz in a short and super scenic but tough loop from Martigny. A 4-day tour was even created to explore more climbs in the area.

You start the ride with a section that will not remain underrated for long: the Petite Forclaz. This should have been the main climb of the 2020 World Championships circuit. It’s not one for the faint-hearted: as soon as you leave the city, the road narrows to pass through the village of Martigny-Croix. The slope immediately exceeds 10% to meander through the vines. As you rise above the Rhône valley you ride through several hamlets and after 4 km at 11% on average you join the main road of the Col de la Forclaz.

At the pass (1527m), change of scenery: you enter the peaceful Trient valley and discover a breathtaking view of the surrounding glaciers and peaks. You descend to the village of Trient and then reach Finhaut, a mecca for Alpine tourism at the beginning of the 20th century.

As soon as you leave Finhaut, the road is single lane and it’s one switchback after another. The slope fluctuates between 8 and 11%. Tour de France themed mileage signs and washed-out inscriptions on the road remind us that the Grande Boucle took this route in 2016. In the distance, the mighty Mont Blanc is clearly visible in good weather. You reach the summit at 1960m after a 10 km climb with little traffic: the road is a dead end.

This is the finish of the Désalpe Reichenbach, a charity event organized in September by local pro rider Sébastien Reichenbach, 2019 Swiss national champion in 2019 and loyal lieutenant of Thibaut Pinot at Groupama-FDJ. With routes for roadies, mountain bikers and families, it allows everyone to discover the Trient Valley and the Finhaut-Emosson region in a friendly atmosphere.

But it’s not over: you can continue the climb to another dam, that of Vieux Emosson. The road leading to it is closed to traffic, and for good reason: it is so narrow that two way traffic is impossible and the slope exceeds 15% over more than a kilometer and a half. You stop at 2125m at the foot of the dam, next to the Vieux Emosson hut. The landscape is alpine with breathtaking views of Lac d'Emosson and the surrounding peaks.

You go back down where you came from. The ascent to the Col de la Forclaz is short and it is even possible to avoid it to reach the valley on the Mont-Blanc Express train.

The descent from the col is pure pleasure. On an excellent surface, you let yourself go at speeds that can easily exceed 80 kph between rare switchbacks. 7 km from Martigny, you join the circuit of the 2020 world championships again and this is where you realize that the fastest riders will surely exceed 100kph to win the rainbow jersey...

The stats: 73 km and 2900m of climbing. One for the col collectors, who can extend their stay in the region to tackle more climbs: Col du Lein, Col des Planches, Sanetsch, Croix de Coeur… and many others. In collaboration with the local tourism board, we designed a tour with hotel, GPS file and telephone assistance which allows you to tick all these passes off your list in 4 days and 3 nights from Martigny. Perfect for an extended weekend with your cycling friends... More information:
