Tirreno-Adriatico 2025 Route stage 6: Cartoceto - Frontignano

Saturday, 15 March – The 6th stage is the hardest of this year’s Tirreno-Adriatico. The riders take on almost 3,500 metres of elevation gain over a 163-kilometre course. It's the only mountain top finish of the week after a 7.7-kilometre climb with an average gradient of 7.8%.

The route is fairly straightforward. The first 120 kilometres are packed with a series of short climbs, before the riders tackle two longer ascents in the final part of the race.

The most eye-catching of the short climbs are crested after 22 kilometres (4.1 kilometres at 4.4%), 39 kilometres (2.9 kilometres at 6.6%), 47 kilometres (1.9 kilometres at 6.2%), 54 kilometres (3.5 kilometres at 6.6%), 74 kilometres (2 kilometres at 7.5%), 85 kilometres (740 metres at 12%), 108 kilometres (5.6 kilometres at 5%), and 114 kilometres (2.7 kilometres at 4.4%).

The riders crest the final of these in Torrone before an undulating descent towards the intermediate sprint in Pieve Torina. At that point, nearly 30 kilometres remain.

This section starts with a long, gradual drag leading to the base of the climb to Le Fornaci, which averages 5.1% over 4 kilometres. A short descent follows into Visso, before another false-flat rise leads to the foot of the final challenge.

The climb to Frontignano is a demanding 7.7-kilometre ascent at 7.8%. The toughest section begins with around 5.5 kilometres to go, where the road ramps up into double-digit gradients for 2 kilometres.

Finish venue Ussita Frontignano is a small ski resort in the Marche region, located at 1,327 metres above sea level.

The first three riders across the line gain 10, 6, and 4 bonus seconds, while 3, 2, and 1 seconds are up for grabs at the intermediate sprint.
