technical info
An Alpine tappone made up entirely of climbs and descents. After just 4 km comes the first ascent to Croce Serra, which leads into the Dora Baltea Valley. A short false flat brings the riders to Verrès, and then it’s three long climbs of about 15 km each, without breaks in between: Col Tzecore (last 4 km over 12%), Col de Saint-Pantaléon, and Col de Joux. After descending to Brusson, the final part begins, always uphill, with the steep pass through Antagnod (up to 11%) ending 5 km from the line.
Final kilometres
At about 5 km to go, a descent begins—initially gentle, then steeper from 3 km out, with a series of switchbacks leading into the final kilometre through Champoluc. The last 1 km includes cobbles up to 400 m from the line, then a steady rise to the finish. Final straight: 80 m on 7-metre-wide asphalt.
