Alto de Letras Challenge

The Alto de Letras Challenge in Colombia is the ultimate cycling tour for passionate riders—and an unforgettable journey for companions. This 7-day adventure features the legendary Alto de Letras and Alto El Sifon, two of the world’s most iconic high-mountain climbs, rising from tropical valleys to high-altitude peaks across some of the country’s most stunning landscapes.

Just arrive in Colombia—we take it from there: includes airport transfers and all transportation, a top-tier road bike, full support on every ride, daily massage, all meals, private accommodation in premium lodges, curated cultural experiences for non-rider companions, and English-speaking guides—so you can focus fully on the experience.

The Alto de Letras Challenge is a once-in-a-lifetime journey through Colombia’s dramatic landscapes, built around the world-famous Alto de Letras. Over 7 days, cyclists take on an epic 80+ km ascent and climb above 3,800 meters—supported every step of the way.

Less known globally but just as demanding, Alto El Sifon is, in our experience, even more rewarding than Alto de Letras. You can expect dramatic mountain scenery, world-heritage towns nearby, and unique high-altitude ecosystems along the route.

Beyond the ride, the journey blends local culture, great food, and historic towns—so cyclists and companions share the adventure, each in their own way.
