Tour of Flanders day! 🤠🤠 Last year, we made this clip about the Geology of the Tour of Flanders: why are those hills so steep? Check it out below, and have fun today!

For the riders today, this is bad news. When the partitions are up, they provide some shelter to the wind. But during today's storm, they'll be down. Perfect conditions for some suffering. The organization is well prepared: behind the finish line, there is a puke station with plenty of buckets 😂.

While the project became an enormous engineering success, it had ecological downsides. The dammed inlets turned from brackish to fresh water, affecting biodiversity. The final dam, of the Oosterschelde, is therefore contains open partitions that only during storms are shut.

Following this disaster, the 'deltaworks' started: the inlets of the Zeeland estuary were dammed, dykes were raised. The project took decades and shortened the Dutch coastline by 700 km. All but one inlet are now dammed: only the Westerschelde, that leads to the Antwerp harbor, is still open.

On February 1st, 1953, disaster struck. A storm surge led to multiple dike breaches, and an area of 150.000 hectare (370.000 acres) flooded. Nearly 2000 people drowned that night. 47000 cattle and 140000 poultry died. This was not the first flood, but it was the worst.

The race will be held in Zeeland, a province in the SW of the Netherlands. Zeeland is an amalgamation of islands in an estuary, where the Meuse, Rhine, and Scheldt rivers meet the North Sea. And with the Dutch hobby of making polders, this land is especially vulnerable for floods.

Today is the day of the Dutch Championships Headwind Cycling, where pro riders get beaten by the mailman! It will be a mild edition, with only a 6-7 Bft westerly wind, but the race parcours is chosen such that there is zero protection: the 9 km long Oosterschelde dam! A dam with a history.

We kriehen sturm! 🌬️
Forget the Tour de France: the Dutch Headwind Cycling Championships will be held on Dec 7! An 8 Bft storm will blow on the 9 km long Oosterschelde dam, and 300 racers will battle it on city bikes. We'll be there with the Geology of Shit Weather!

What would the season's Grande Finale of @Il_Lombardia be without geology!

You'll see the leaves falling over the folded and pushed up limestones - and dolomites of course, the name giver of the Italian Alps!
And you'll see the beautiful shores of Europe's deepest lake outside of Scandinavia, Lake Como.

And there's so much more! Luckily, Bram Vaes and Martina Rocca of the University of Milan-Bicocca write it down for you in a blog!

Last day of the #Zurich2024 world championships, the men will have to show what they’re worth! And they’re lucky the race wasn’t 24000 years ago, because they’d had have to ski the entire thing back then 🥶

Stefan Heuberger at ETH Züich explored the route for you and took pictures. In his blog on our website, he explains where the riders climb the remains of the majestic glaciers of the last ice age!

Why is that hill there? Why is it so steep? How was this valley created? Or why is there a lake here? We list the best features for you to recognize and enjoy during the race because as you know by now: there is just no cycling without geology.

Valleys that were once hundreds of meters deep are now filled in to form relatively flat roads for our riders.
It was the Last Glacial Maximum, around 24,000 years ago, that shaped most of the course today.
Geologically speaking that was basically yesterday. It does give us the opportunity though to make geology even more visible during the long road races.

The road race takes us to beautiful geological sites along the route like drumlins, valleys, a tafelberg and gorgeous lakes.Stefan Heuberger of ETH Zürich takes you on a tour to see but also shows you what you can’t see anymore.Ice ages and warmer periods shaped the landscape on our course. Most of it we can’t see anymore because time and erosion made them disappear under layers of sedimentation.

The future of cycling is in the hands of the juniors and U23 riders racing against the clock today and tomorrow.
But how can geology help with future-proof storing nuclear waste from Zurich's three nuclear power plants?
Thomas Schouten of ETH Zürich explains in our blog:

We also learn how the creation of the Alps tens of millions of years ago now comes in very handy when dealing with a nuclear problem. And how a boring tectonic situation makes that all possible. Enjoy the blog and the race!
