Morning fog lifts off a high Andean road and the first pedal stroke feels like a small argument with gravity. You climb through cloud forest, then past páramo slopes that thin into sharp, high-altitude ridgelines; the road keeps rising and the air grows noticeably colder and thinner. That is Alto de Letras: an extended, paved ascent that challenges legs and rewards eyes.

Acclimate before hard efforts
Spend at least 24–48 hours at moderate altitude (Bogotá or Mariquita) before the big climbs to reduce altitude-related fatigue.
Start rides early
Begin before dawn to take advantage of calmer winds and more stable weather on high ridgelines.
Fuel frequently
Aim for 200–300 kcal per hour on hard climbs and prioritize electrolytes to prevent bonking at altitude.
Know your descent
Descending after long climbs can be technical; check brakes and practice cornering on warm-up roads.
Road helmet
Protects on fast descents and is mandatory for group rides.
Clip-in cycling shoes
Improves pedaling efficiency on long climbs and steep pitches.
Layered cycling kit (base, thermal, windproof)
Temperature can vary from warm valley rides to near-freezing at summit elevations.
Hydration pack or large bottles
Frequent fluid and electrolyte intake is critical during multi-hour efforts at altitude.
