The time it takes to complete a luge run varies significantly between a recreational "summer luge" and a professional Olympic-style "ice luge." For a professional luge run on an artificial ice track (like those in Whistler or Lake Placid), a single run typically takes between 48 and 54 seconds. During this time, athletes reach speeds of over 140 km/h (87 mph). For a recreational summer luge (like the Skyline Luge in Queenstown, Singapore, or Mont-Tremblant), a single descent usually takes between 3 and 5 minutes depending on the length of the track and how much you use the brakes. These tracks are usually about 600 to 1,200 meters long. Most recreational venues sell tickets in "3-ride" or "5-ride" bundles because the experience is so brief that visitors want to repeat it to master the corners. If you factor in the chairlift or gondola ride back to the top and the wait time in line, a full "luge experience" of three rides usually takes about 60 to 90 minutes. Professional lugers, however, spend hours in "track walks" and mental preparation for a race that is decided by thousandths of a second in under a minute.
