ENDURO - Exciting and Professional
Call it Track Enduro, Triple Crown racing, anything you like.  It's a no-holds-barrel, long distance team race that takes hours to win.  In 1981-82, after years of development in its Michigan birthplace, track enduro was growing strong in every direction.
   Until you've seen a track enduro, you couldn't imagine the tremendous thrill created by fifty wildly-modified racing machines all on the track at once coming around on the parade lap looking for a green flag and a start of a race that won't end until the winning team has logged 250-350 miles, comparing to long distance style auto races
   This is non-stop, furious track action, pit stops and well trained teamwork to captivate thousands of fans
