40 solar bikes around the Alps

From June 17 to July 9, 2022, the Sun Trip Company organized the “Sun Trip Alpes”.

From Grenoble to Lyon, passing through Switzerland, Austria, Slovenia and Italy, this project is part of the international dynamic created by the Sun Trip since 2013, by reaching a public interested in living this experience of solar autonomy.

On the roads of the world the Sun Trip shows that solar energy adapted to the electric bike can create speed feats and universal emotions.

With this format, the idea is to involve an ever-wider public to demonstrate that the solar bike can allow anyone to climb the greatest Alpine passes.

By drawing on the richness of the 40 adventurer profiles registered, the Sun Trip Tour has carried a concrete and human ecological awareness message throughout the 7 stages and 2500 km of the route.

The Sun Trip Alps is back in 2023, with a new route!

The itinerary

In France, Switzerland, Austria, Slovenia and Italy, the 40 solar adventurers have once again demonstrated the effectiveness of new energies applied to cycling, and the way in which our project is received internationally.

The interactive map

Essential tool for the follow-up of the adventure, the live map will have known this year its greatest success. With the return of the “challenge of the passes by point”, the map allowed to calculate the classification in real time of the points collected by the participants according to their route.

Today, we propose you a replay of the route. Thanks to Yann Cauquil for this work. More adventures on

Companies in the adventure

Since 2018, the Sun Trip has offered companies the opportunity to join our adventures by registering employees (on all or part of the route) or by sponsoring a participant who has already registered.

This Sun Trip Alpes 2022 edition was a new opportunity to demonstrate the corporate potential of our events. Here we summarize some of the communication tools used to tell the story of these experiences.

The Sun Trip Alpes with France 3 Auvergne Rhône-Alpes

This year the Sun Trip has the honor to be broadcasted every day at 6:45 pm or 7:25 pm on France 3 AURA. Thus, the general public could follow the adventures of the participants on air. About fifteen episodes which are included in the series “Préserve ta montagne”. This program is online on the youtube chanel of France 3 AURA.

The pre-start in Lyon

The Sun Trip Alpes is taking its bearings with an introductory stage between Lyon and the Col de Porte, where participants will gather before the official departure from Grenoble on the GIANT innovation campus.

The pre-start was attended by Sonia Zdorovtzoff and Hélène Dromain, respectively deputy mayor of Lyon and vice-president of the Lyon metropolitan area.




Stage 1: Grenoble – Chambéry – Annecy

The first pictures of the departure ! From Grenoble to Savoie, through the Chartreuse mountains, a meeting with 200 children in Chambéry, a nod to our major partners Aktid and EDF, the day was intense.


After a hook on the starting line in 2013, in front of the INES, the peloton spent the night at the edge of the Bourget lake, in the campsite of our crazy years (2012, 2013, 2015, 2018).

On Saturday, June 18, the group crossed the superb Bauges massif, between Lake Bourget and Lake Annecy.

On the way, a small meeting was organized at La Féclaz with young people from the Universal National Service and Daniele Gonano was inducted as official Groupama team.

Stage 2: Annecy – Andermatt

First major stage of the project, the journey between Annecy and Andermatt offers the first border crossing towards Switzerland.

Part of the group chose to cross Lake Geneva and Evian, while the majority of the group took the road to Chamonix before arriving in the Valais. The best climbers took the opportunity to get points at the top of the Emosson dam road.

From this first big stage the choices of routes are very different, and we can’t wait to know the results of the solar challenge.

Through the Swiss mountains !

A nice overview of these first hundreds of kilometers passing through our Swiss neighbors, crossing breathtaking mountainous landscapes.

The arrival in Andermatt

The suntrippers have all reached the first stage outside of France on time. Here are some pictures of the special welcome offered by Andermatt Swiss Alps, with accommodation, meals, meetings and entertainment.

Stage 3: Andermatt – Innsbruck

The start of the 3rd stage was given on Thursday June 23rd at 10 am. The peloton stayed together between Andermatt and Disentis, over the Oberalp pass. After a last meal together, offered by Catrina Experience, the group headed for the next stage, Innsbruck in Austria, 300km further on.

As at the beginning of each stage, the yellow jersey was given to the rider with the most points on the climbs. Thanks to a good strategy (analyse route) ) the Frenchman Hugo Rousselot is now in the lead, with 550 points, against 530 for Emile Rivoire (Team GIANT – Hexatech) and 475 points for Sibylle Felder.

The itineraries then varied quickly, with the group of top climbers heading for the Stelvio Pass in Italy (awarded 100 points!), while some “arrows” decided to reach Innsbruck a day early…

Others cut through the middle, via the Albula road, riding in small groups until nightfall.

Passage of the Stelvio in Italy – 2757m 

Kilian Weigand, on the road to the Stelvio! In spite of an intense rain, the young German took the road of the mythical pass of the Dolomites, located in Italy. Before him Emile Rivoire, Hugo Rousselot and Stéphane Bujadoux had been able to count on better weather to reach the summit at 2757m!

Arrival at destination

More than 300km after Andermatt, we welcome the SunTripers at the base camp located 15km from Innsbruck. It is under the sun and especially in the middle of Austrian folklore that we meet, the time to recharge and have dinner all together.

Stage 4: Innsbruck – Bled

On the morning of Sunday, June 26, 2022, the group starts the Innsbruck-Bled stage under a beautiful sun. Before leaving, the yellow jersey was again handed over, this time between Hugo Rousselot and Emile Rivoire (GIANT-Hexatech team).

At its shortest, this 2.5 day stage was just over 300 km long, while Emile rode 632 km and covered more than 12,000 meters of positive altitude difference!

Crossing into Slovenia

We discover the first pictures of the SunTripers who cross this new border, and arrive at the halfway point of this alpine route. The landscapes do not cease to give them desire to continue, they will rest nevertheless one day in a lodge in edge of lake, before taking again the road Thursday 30 morning.

The Dolomites

Crossable by the northern part of Italy, some participants share with amazement some pictures of this mythical massif. A detour that will take them back to Austria before reaching Slovenia.

The solar challenge: Emile Rivoire solid leader! 

We can say it, Emile Rivoire (Team GIANT campus – Hexatech) keeps his yellow jersey at the end of stage #4. He reached the base camp in Bled, Slovenia, having ridden 540 km from Innsbruck and climbed 12 major passes, including through the Dolomites.

A total of 12,000 meters of positive elevation gain over the last three days. And since the start in Grenoble we estimate that the leaders have already climbed 40,000 meters of positive altitude difference!

The arrival in Bled

It is in the late afternoon that we meet on Tuesday, June 28, in our lodge at the edge of the lake Bohinjsko, at 30km from Bled. It is with difficulty that some of us reach this new stage, crossing the Austrian border with 18% passages.

The SunTripers take advantage of their free Wednesday to work, rest, enjoy the lake and think about their next route to Conegliano.

Stage 5: Slovenia – Italy

This stage between Slovenia and Italy started with a day of break around the Slovenian lakes, towards Bled. A day to rest, to tinker and to prepare the next itineraries.
