The Hitch said:Boyaca is colder and can be pretty grim during the rainy season. Carrara trains in Antioquia, on a different mountain range.
Not necessarily during December through February- but even if the weather changes, they can easily go nearby to Cundinamarca or Santander-which is a hidden jewel for cycling due to terrain, some cluel climbs above 4000 meters & weather conditions ( Serpa's home & training camp during the off season)
