The El Alto de Letras Challenge is the ultimate test for passionate cyclists—and an unforgettable journey for companions. Based in the lush heart of Colombia, this tour is built around conquering the legendary Alto de Letras, often called the world’s longest paved climb. Stretching over 80 kilometers, this ascent takes you from tropical lowlands to misty Andean heights, climbing more than 3,700 meters and traversing multiple climate zones. Revered by pros and cycling enthusiasts alike, Letras is not just a ride—it’s a rite of passage, a story of endurance, and a celebration of cycling’s purest spirit.

But the adventure goes beyond the climb. Each day blends achievement on the bike with immersive cultural experiences, local cuisine, and moments of connection—so everyone, riders and companions alike, shares in the journey.
