The route is relentlessly rolling, both in terms of terrain and elevation, with no long climbs but an abundance of sharp, punchy ramps, particularly on the gravel sections. The riders will tackle approximately 82 km of gravel roads across 16 sectors (13 of which are shared with the women’s race). The gravel is well-maintained, compact, and free of grassy intrusions, with only minimal loose stones on the surface.
The race begins in Siena (Stadium/Fortezza Medicea area), with the opening kilometers on undulating asphalt roads leading to the first gravel sector (4.4 km), a perfectly straight stretch with a gentle descent and only one curve midway.
A short asphalt section brings the riders to the second gravel sector (4.8 km), the first significant challenge of the day. This sector includes a long uphill segment with gradients exceeding 10%. The peloton then reaches Radi and the third gravel sector (4.4 km), immediately followed by the fourth, La Piana (6.4 km), which is less demanding in terms of elevation. After reaching Ponte d’Arbia, the athletes join the “Cassia” state road all the way to Buonconvento.
Next comes the Montalcino climb (on asphalt), the second major ascent of the day with its 4 km at 5%. After Torrenieri, the riders face the fifth (11.9 km) and sixth (8.0 km) gravel sectors, separated by just 1 km of asphalt. Both sectors are challenging, undulating, and rather technical, with frequent curves and short ups and downs. After crossing Buonconvento for the second time, the course tackles the new Serravalle sector (9.3 km), which leads directly into the next gravel segment – San Martino in Grania (9.5 km). This lengthy section features rolling terrain in its early stages and concludes with a winding climb that reconnects to the asphalt road.
Once in Ponte del Garbo (Asciano), the ninth gravel sector (11.5 km) begins. This is the race’s most demanding sector, primarily uphill with sharp undulations, including several steep ups and downs near Monte Sante Marie, where gradients spike dramatically within very short distances. After Castelnuovo Berardenga, a brief asphalt section brings the riders to Monteaperti, where the tenth gravel sector (600 m) awaits. This short but brutal ramp features double-digit gradients. The course then returns to asphalt around the town of Vico d’Arbia, where the athletes enter a 30 km circuit.
After Pieve a Bozzone, the circuit includes the 11th gravel sector (Colle Pinzuto, 2.4 km), with gradients reaching 15%. A few kilometers later comes the 12th sector, Le Tolfe (1.1 km), characterized by a steep descent followed by a sharp ascent with a maximum gradient of 18%. Shortly after Le Tolfe, the route introduces a new sector which has never been tackled before – Strada del Castagno (13th sector, 700 m). This leads into challenging asphalt sections through Pontignano, Ponte a Bozzone, and San Giovanni a Cerreto, where the riders take on the 14th gravel sector (Montechiaro, 3.3 km), already featured in the race’s earlier editions. The loop concludes in Vico d’Arbia. The athletes then face the Colle Pinzuto (15th sector) and Le Tolfe (16th sector) sectors a second time before heading back toward Siena, with just over 10 km left to go.
Last KM
The final past of the race begins outside the city of Siena, following wide roads and long straight stretches connected by broad curves. The terrain first descends, then moves to a gentle uphill leading to the -2 km mark. Here, the riders enter Via Esterna di Fontebranda, where gradients reach up to 9%. At 900 meters from the finish, the course passes through the Porta di Fontebranda and transitions to cobblestones. The gradient exceeds 10%, peaking at 16% on Via Santa Caterina, at around 500 m to go. A sharp right-hand turn onto Via delle Terme leads into Via Banchi di Sotto. From 300 meters out, the road gently descends. At 150 meters, a right-hand turn onto Via Rinaldini leads the athletes into Piazza del Campo. The final 30 meters descend at 7%. The finish line is on a flat stretch in the iconic square.
