A redesigned route

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

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

The loop went all the way to Germany before a return through Switzerland and a finish on the banks Annecy lake! The arrival took place on July 1st 2023.

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

This edition didn’t include any speed challenges, but we gave 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 kept the idea of a yellow jersey to reward the most successful adventurers, and we added the idea of a blue jersey, which will be awarded to the best ranked adventurer over 50 years old!

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.

The prologue

New for 2023: on the eve of the start of the adventure, we have organized a 70 km prologue around Lac du Bourget, designed with Groupama, for our partners and their employees.

Companies in the adventure

Since 2018 the Sun Trip has been offering companies the chance to join in our adventures, through communication operations or by registering employees (on part or all of the route). So many opportunities to work on the project, making it ever more adapted to the CSR or internal/external communication issues of its supporters. Thanks to our partners Alpes 2023 :

Savoie-Nice: the corporate leg of the Sun Trip 2023

A 4-minute film retracing the superb Savoie-Nice stage, which opened the #SunTripAlpes 2023! Among the participants in this stage were 20 employees from 6 partner companies, for a unique opportunity to pass on the solar bike travel bug and share the values of the Sun Trip. EDF, Aktid, Groupama, Vinci Airports, Bouygues Energies & Services, ASE-Energy: bravo and thank you for your support, you were the pioneers of the next 100% corporate Sun Trip projects.

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.
