History
The route follows long-standing Andean roads linking Tolima valleys to higher towns; Alto de Letras rose to global prominence through cycling culture rather than historic settlement.
Conservation
The high-elevation ecosystems are sensitive — stick to paved roads, avoid littering, and support local guides and community-run lodging to help sustain the area.

Acclimatize before the big day
Spend a night in Mariquita or arrive a day early to let your body adjust to altitude changes before the 3,200+m climb.
Pace the climb
Sustainable power beats hard surges — stick to threshold pacing on long pitches to avoid bonking mid-climb.
Hydration and fueling plan
Carry easily digestible carbs and plan feed stops; support vehicles supply bottled water but start hydrated and snack frequently.
Bike fit and gearing
Use a compact or triple crank and lower gearing for long, steep grades; confirm brakes and tires for wet descents.
Road bike with low gearing (rental available)
Low gears and a reliable drivetrain make the long sustained climbs manageable.
Lightweight waterproof wind jacket
Protects against cold, wind and cloud-forest drizzle at higher elevations.
Hydration pack or large bottle cages
Allows continuous access to fluids on long climbs when support stops are spaced.
Padded cycling shorts and chamois cream
Comfort on long saddle hours is essential for performance and recovery.
