A St. Cloud snowmobile motocross racer has captured a gold medal at the Winter X Games, coming out on top for the sixth time among fellow competitors who are either amputees or partly paralyzed.

Mike Schultz, 35, who lost his left leg above the knee in a 2008 snowmobile incident while racing, claimed gold on Thursday in Aspen, Colo.

Schultz engineered a prosthetic for his injured left leg and in 2010 started BioDapt. Inc., which helps athletes and wounded soldiers return to the athletic pursuits they love.

"Two of my competitors in [the] final wear my equipment — the "moto knee" and "versa foot" — and are enjoying their sport again," said Schultz, who describes himself as a self-trained engineer.

Schultz, a member of the U.S. Paralympic Snowboard team, will compete in February in boardercross and banked slalom racing at the 2017 International Paralympic Committee World Para Snowboard Championships in British Columbia.
