Circuito de Navarra
Circuito de Navarra
The Navarra Circuit is a unique infrastructure. Its 3,933 metres form an attractive, very technical route. With the capacity to hold Formula 1 training sessions, the circuit is prepared to receive the peloton and, thus, join a select list of circuits such as the Jarana, Jerez and Assen that have already hosted the Vuelta on previous occasions.

Circuito Navarra -Logroño
Logroño is built on conglomerate rocks, sand, gypsums and limestone rocks from the Oligocene to Miocene Periods (34 to 6 million years ago, shown in salmon and yellow in the diagram) and around the Ebro River meadows and its tributaries, formed by Quaternary sediments (grey in the diagram).
These lithologies, along with the hillside orientations, days of sunshine and yearly rainfall are, in the La Rioja area, fundamental elements for grapevine cultivation in order to make high-quality wines, as they result in well-ventilated poor soils that are the ideal environment for grapevines to thrive in.
At the start of this “time trial” we find ourselves in Navarra with a route that has barely any differences in altitude, with extensive plains around us except for some mountain ranges that peak over the Northern spurs of the Cantabrian Mountains. The journey to Logroño is part of the “French Route of The Way of St. James”.
The materials we find, clay and sand, result from the erosion of bordering mountain ranges. As those mountain ranges were created, a depression formed that was continuously being filled, while a river network whose main artery is the Ebro River became embedded, generating lands that are appropriate for growing crops, especially grapevines.
We cross the Ebro River to arrive in Logroño, capital of the Autonomous Community of La Rioja. Along with its winegrowing wealth, La Rioja also has over 110 dinosaur fossil sites, many of which have routes and trails, such as Enciso's Dinosaur Trail that covers seven sites, or the Igea site that also contains a fossilised trunk.
