Sun Trip Alps 2022

Discover the beauty of the Alps!

After Auvergne-Rhône-Alpes, Corsica and Brittany, the Sun Trip is launching a new regional edition of its adventures: a 100% Alps loop!

The start will be in Grenoble in mid-June 2022! The finish will be celebrated in Lyon, the Sun Trip’s home base since 2018.

An alpine but accessible route!

The Sun Trip Alps will be a new great chapter in our dynamic, with a crossing of 6 countries (including 5 member countries of the European Union). A loop of just over 2000 km, with 7 major stages and welcomes every 2 to 4 days, which will be a unique opportunity to discover the richness and diversity of the Alps.

On the programme are some of the most mythical passes in the Alps, more accessible discoveries and stopover sites in the middle of nowhere. You will be surprised by the beauty of this area! The complete course will be presented in the winter.

We will propose a prologue from Belgium (without supervision of the stages), and 3 stages opened to guests: “Lyon – Grenoble” before the departure, then the first stage at the departure of Grenoble and finally the stage “Val Cenis – Lyon” in conclusion of the project.

The Sun Trip Alps will not include any speed challenge, but as in 2019 will offer a game of bonus points to be picked up at the top of the biggest passes or on the banks of certain lakes.

Dare the freedom of the solar bike and go beyond your limits!


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

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

With the regional projects, 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 of the Alps for this 2022 edition!
