Seven days from Bogota two up. Hmmmm. It's almost painful to be in such a beautiful country with great mountain riding for only a week. I am currently in Colombia and would suggest heading north to Medellin. Really fun riding from Bogota to Medellin. Then head over to Guatape and El Piņol and east to Bucaramanga, Pamplona, up to El Cocuy, San Gil and back to Bogota.
I think you could do that in a week. Forget about the Costa Antlantico and all the awesome riding up there. Cartegena, Taganga, Tayrona, Cabo de la Vela will have to wait until next trip.
