Extreme sports
In the air balloon jumping, base jumping, parachuting
In the water kayaking, wakeboard, rafting, windsurfing, kitesurfing (flysurfing)
In the mountains mountain biking, climbing and climbing without protection, motocross
In the city bull running (in Pamplona), building jumping, skateboarding, street
rollerblading (armed with 31 rollerballs and an armored body suit, riding on his feet,
back and front as he pass shocked pedestrians and cruises at speeds up to 50 miles
per hour)
I think that the only one I could try is mountain biking.
