The Sun Trip through the Alps – Season 2!

Following the success of the Sun Trip Alps 2022, we are back for the tenth anniversary of the project with a second 100% alpine edition, from Savoie Technolac (June 15th) to Annecy (July 1st). 

Departure : June 15th

For this second season, the route will be designed in the opposite direction, with a major highlight planned between Savoie and Nice, following the mythical Route des Grandes Alpes. The departure is planned for June 15th 2023.

The route will then go up through the Italian Alps, to visit some of the highest passes of the chain, while the less adventurous will be able to cut across the Po plain!

The loop will go all the way to Germany before a return through Switzerland and a finish on the banks Annecy lake! The arrival is planned on July 1st 2023.

The Sun Trip Alps will be another great chapter in our adventure. A loop of about 2500 km, with 8 stages and welcomes every 2 to 4 days which will be as many opportunities to discover the diversity of the Alps, carried by a collective dynamic.

This edition will not include any speed challenges, but we will be giving even more value to the Solar Challenge, following on from the successes of 2019 and 2022, with points to be picked up at the top of the biggest passes or at certain sites of Alpine heritage.

We will keep the idea of a yellow jersey to reward the most successful adventurers, and we will add the idea of a blue jersey, which will be awarded to the best ranked adventurer over 50 years old!

The participants

Various profiles, all motivated to give the best of themselves in a friendly spirit of discovery, on the 2000 km of the route through 4 countries.

Companies in the adventure

Since 2018, the Sun Trip has offered companies the opportunity to join our adventures by registering employees (for part or all of the route) or by sponsoring a participant who has already registered. These are all opportunities to work on the project, to make it more adapted to the CSR or internal/external communication issues of its supporters.

Solar bikes – Instructions for use

One of the richnesses of this project comes from the impressive diversity of solar bikes. For some regulars, this Alpine edition is an opportunity to modify their bike to better climb the passes. Others will avoid the steep climbs and favour a faster, more aerodynamic bike.

As in 2022, it is possible to buy or rent a solar bike through the services of our partner SolarMoov. To design your own, you can use our instructions or write to

Pre-registration form

Since 2013, the objective of the Sun Trip is to promote new energies by relying on the human wealth of its participants.

In the wake of the development of the electric bike, in all its forms, the Sun Trip has been participating for 10 years in the promotion of the self-sufficient assisted bike.

The idea is to involve an ever-wider public to demonstrate that the solar bike can allow everyone to (re)discover cycling and climb the greatest passes in the Alps for this 2023 edition!

The contribution of energy on a hybrid machine such as a bicycle allows to completely revisit the practice.

  • It will allow you to travel differently and discover the mountain environment beyond our borders,
  • Learn how to design and use a solar bike,
  • Include social causes such as the apprentices of the Fondation d’Auteuil in 2021 and 2022,
  • Enable a retired person to regain his “youthful legs”,
  • To offer the opportunity to a person with a disability to make up the difference,
  • To push a good sportsman to become the “Bertrand Picard of cycling”.

On the roads of the world (Kazakhstan 2013, Turkey 2015, China 2018, Europe 2021), the Sun Trip shows that solar energy adapted to electric bicycles can create speed feats and universal emotions.
