One of the most feared and revered climbs in all of Italy, the Passo del Mortirolo is a true test for any cyclist. Often referred to as the “most brutal climb of the Giro d’Italia”, it rises relentlessly for 10.5 km with an average gradient of over 10% — and ramps that hit a leg-burning 18%. This climb demands respect. It’s not just the gradient, but the way it never lets up — switchback after switchback through dense forest, with barely a moment to recover. It’s steep, narrow, and raw. But reaching the summit is an unforgettable achievement. At the top, you’ll find a monument to Marco Pantani, the legendary climber who made the Mortirolo famous with his explosive attacks. If you love a challenge, this is one of the greatest you’ll ever face on a bike — and one you’ll never forget.
