“Take a ride down the landing hill of a Nordic Ski Jump … in an inner tube! Gain speeds up to 50 mph and enjoy the thrill of soaring just like an Olympic Nordic ski jumper. (These are the same ski jumps that the today’s Olympic-level athletes train on!)
Extreme Tubing will take place on the Nordic Ski Jumps featuring the Larger Hills (K64 and K90) and Small Hill (K40). The landing hill where your ride starts is constructed from a start-of-the-art plastic surface that slides just like snow when wet. Participants will be required to do the K64 before progressing to the K90.” – utaholympiclegacy.org
