Each of the four stages is characterised by a very different geological story – and David De Vleeschouwer will tell it just prior to each stage, on the morning of race day. He will describe the landscape and the altitude profile of the stage and explain in a general and understandable way the climate and the state of the oceans at the time when the geological formations were formed.
Both cyclists and geoscientists divide Germany into three main areas: Lowlands, low mountain ranges and the Alps. All of them have been shaped, for example, by ice ages, sea level changes, plate tectonics and meteorite impacts. The rocks and stones and sediments tell of their history, which in some cases goes back more than 250 million years.
