The fourth stage of Tirreno-Adriatico 2026 will present riders with a demanding mountain challenge as they tackle a 213-kilometer route from Tagliacozzo to Martinsicuro. With 2,781 meters of vertical climbing ahead, the stage promises to be a crucial test for general classification contenders.

Challenging Route Profile

The route features four significant climbs that will test the peloton’s climbing abilities. Riders will first encounter the ascent to Ovindoli, followed by the challenging Valico delle Capannelle. The latter part of the stage includes the climbs of Castellalto and Tortoreto (Badetta), which could prove decisive in determining the day’s outcome.

Del Toro’s Mountain Test

Mexican talent Isaac del Toro (UAE Team Emirates) will face one of his biggest tests of this year’s race. The young climber’s abilities will be thoroughly examined across the multiple ascents, particularly on the final climb of Tortoreto, where attacks from the main contenders are expected.

Key Battlegrounds

The succession of climbs in the final 50 kilometers will likely serve as the primary battleground for stage honors. The Castellalto climb could see initial moves from the favorites, but the Tortoreto ascent will likely be where the decisive attacks take place. With its steep gradients, this final climb could create significant time gaps in the general classification.

Cycling fans can expect an exciting day of racing as the peloton tackles this challenging mountain stage. The combination of distance and elevation gain will ensure that only the strongest riders will contend for victory in Martinsicuro.
