Geology of the Tour de France

We really hope you enjoy our clips and blogs about the Geology of Cycling. There's much more where that came from, but to keep making these, we're gonna need your help!

All blog writers and presenters of Geo-Sports are volunteers, but our editor and film crew are independent professionals. So to also make a 2025 season, we've started a Crowdfunding campaign.

Please spread the word, donate, and we'll also see you in 2025 🙏🚴🌋!

Just in case y’all needed a thrust fault 😘

Alpe d'Huez day! Two years ago, @marjieparj made this clip for the @LeTourFemmes about how the Alpe is folding without breaking!

Enjoy the climb! And the spectacular folds...

Three years ago, @marjieparj made this clip about the Puy Mary, the Cantal volcano's highest peak not far from today's finish line. It was then the finish for a stage in the @LeTourFemmes!

Today's Tour de France stage ends at Le Lioran, at the top of the Cantal Volcano, Europe's larges stratovolcano. Two years ago, we made this clip: How volcanism led to the invention of the bicycle!

@MatteoJorg: all built on the remains of a much older mountain belt indeed!
