Vidor, Italy · Tuesday 1 December 2026
Running through the Prosecco hills of Conegliano Valdobbiadene in early December means dealing with a relentless, hilly course that will test your legs from start to finish. The terrain constantly pitches upward and downward, climbing from 140 meters to over 560 meters as the route winds through UNESCO-protected vineyards and rolling countryside. You'll experience the peculiar challenge of trail running through wine country, where narrow paths snake between carefully tended grape vines and stone walls, forcing you to stay alert with your footing while your quads burn on the climbs. The cooler December air will feel refreshing at first, but the accumulated elevation gain across the full marathon distance means you'll be working harder than a road marathon at similar altitude, grinding through sections where the trail gets steep enough that walking becomes necessary even for experienced runners. Expect your legs to feel heavy well before the halfway point, not just from the climbing but from the constant engagement required to maintain control on the descents. What makes this course different from typical trail marathons is that you're constantly running through the landscape that produces the region's famous wine, passing wineries and cellars tucked into the hillsides. The visual reward of those cypress-lined slopes and terraced vineyards provides mental relief during the harder pushing sections, though the scenery won't distract you much when you're struggling on steep pitches. The trail surface itself varies between packed dirt, loose gravel, and rocky sections that demand focus with every step. By the time you finish, you won't feel like you've just run a marathon, you'll feel like you've been through a serious mountain workout compressed into road marathon distance, with sore quads and calf muscles that will remind you for days that December running in hilly wine country leaves no stone unturned.
