		| Partnering with Skyline Adventures based out of Whistler, B.C., Canada Olympic Park is delighted to bring this leading-edge technology to Calgary. You will ride in a comfortable harness and fly down a unique cable system, reaching speeds between 120 and 140 km/h. Calgaryıs highest vantage point, the 90-metre ski jump tower at the Park, provides a jump line that is 500-metres long with a vertical drop of more than 100 metres. | 
	
 
Cost is $49/trip, but sounds like money well spent
