Conquer your limits at the original mountain bike race that traverses the continental landmass from coast to coast-from Pacific to Atlantic-is no easy day at the beach. Between its sea-level start and finish, the 275K route crosses five mountain ranges forcing you to climb an elevation gain of 12,000 m! The daunting terrain is so harsh that half a millennium ago it took Spanish conquistadores led by Juan De Cavallón 20 years to cross the land of Costa Rica from the Pacific to the Caribbean Sea; today, following almost the same trails they blazed, modern-day explorers racing on mountain bikes will do in 3 days.
