Since 24 June 2022, the "Géo-Tour de France" website has been online for sports editors, cyclist commentators and cycling racing enthusiasts. The website www.geotdf.org describes the natural scenery of each stage of the Tour de France: the different landscapes and what they show from the depths of the Earth, both for male and female races. Do you know which dinosaurs have been updated along the way?
Cyclists - and their spectators - are very interested in the landscapes they cross during the Tour. What are the origins of the mountains, immense plains or steep escarpments that animate the different stages? For geologists who love cycling, live streaming of a cycling race is the perfect opportunity for a geological excursion. This is how the Geo-Tour de France blog was born www.geotdf.org, to help spectators and cycling commentators appreciate the geology of the tour. For each stage the knowledge of the landscapes and the treasures they contain are presented by a group of enthusiasts from the University of Rennes 1 (around Guillaume Dupont-Nivet, CNRS, Géosciences Rennes) and 6 other countries, under the initiative of Douwe van Hinsbergen, Professor of Geology at the University of Utrecht.
The tour of ancient continents
This year, the Tour de France crosses the remains of three ancient continents, the traces of the impact of a meteorite that marked the end of the dinosaur era, the chalk landscape of the "white cliffs of Calais", extinct volcanoes, pieces of Saudi Arabia in Paris and many other geographical and geological phenomena.For the men’s race, www.geotdf.org follows a major geological phenomenon along the way and explains the underlying processes. The women’s race takes place in geological times that are getting older and older every day, and blogs take the reader into these worlds and their mysterious inhabitants.
The tour of geological times
The blog examines the ancient worlds that lie beneath the landscapes along the route. They are the sum of a story that spans millions or billions of years.The website explains how modern landscapes along the route have been created, the rivers and glaciers that flow through them, the soil characteristics and natural disasters such as landslides that can occur at any time.
Share images and comments on @geotdf
Anyone can share photos and ask questions via the #GeoTdF Twitter hashtag, which will be powered by daily comments via the @geotdf Twitter account. Comments are not limited to the Tour de France; the Twitter account explains the geology of cycling races around the world throughout the season.
Seven countries, seven languages
Researchers from seven countries are participating in the Géo-Tour de France. The site features contributions from the Universities of Montpellier and Rennes, Utrecht and Amsterdam (Netherlands), Birmingham (UK), Münster (Germany), Granada (Spain), Utah (USA), and various geological services (France, Denmark and Greenland, etc.).
Geo Tour de France website: www.geotdf.org is available in English, French, Dutch, German, Spanish, Italian and Danish.
