Modeled after Gravity in Bolivia, this Colombian/Ecuadorean-owned extreme mountain-bike company offers a 50km downhill adrenaline overdose on two wheels through the Cañón del Río Suárez, with catering by Gringo Mike's. It's a high-adrenaline, all-day affair that takes in absolutely epic countryside. If you don't own padded cycling shorts, consider stuffing your pants with household sponges!
