The race is typically decided in the mountains, where stages climb into the Andean highlands at elevations that can exceed 3,000 meters. Altitude becomes the defining variable, turning steady climbs into selection points and rewarding riders who can process oxygen efficiently in thin air. Time gaps open on the longer mountain stages, and the general classification is usually settled by whoever can sustain power at elevation rather than by a single explosive move. Flat or rolling stages exist, but they serve mainly as recovery days between the climbing tests. The race rewards stage-race completeness, climbers who can time trial reasonably well, and anyone who has spent enough time at altitude to avoid the physiological penalty that catches riders arriving from sea level.
Race type
Six-day stage race through Colombia, a showcase for Colombian climbing talent at altitude.
Altitude factor
Stages at 2,600m and above test altitude adaptation and oxygen efficiency.
Typical winner
A Colombian climber who thrives at altitude, or a foreign GC rider who can adapt to the thin air.
