Teambuilding and adrenaline
Rope jumping
Adrenaline in your hands - rope jumping could be described like that. Defacto it's a simple rappelling, but upside down. The feeling is like you're running vertically down like spider-man! The abseiling equipment is behind the back and the runner corrects the speed by holding the rope in front of him.
