Fastest Non-Motorized Human Sport ON Earth
I have competed in the sport of speed skiing for 12 years, professionally for the last five. Internationally I am ranked 14th out of 100 professional racers. During the summers, I am cross training for ski racing while operating my water-ski school in Lake Tahoe, California. For the last 10 winters I am based in Europe and more recently in VARS, France near the famous "La Grave" extreme ski resort. Vars Ski Resort is host to one of the Speed Ski Pro Tour stops in Europe. Besides being one of the largest and fastest tracks on the circuit, this resort offers a unique racing advantage in that a competitor can train daily on The local World Record capable Speed Ski track.
The Current World Record is an awesome 152 MPH set in 1997 at VARS Ski Resort. My Personal record that day was set at 145 MPH only 7 MPH off the World Record. The difference then was that of my hi-speed confidence and experience, something I have since addressed in training. Speed skiing for about ten years, with 6 years on the US Speed Ski Team, resulted in a lot of experience that has evolved into a formidable professional quest for speed.
