Iditarod Trail Invitational,
Iditarod Trail Invitational,

The original Iditabike no longer exists,

but the Alaska Ultrasport Iditarod Trail Invitaional beginning in 2002 stepped in to fill the void. Owned and operated by Kathi and Bill Merchant, the Alaska Ultrasport is two races in one.  The largest and (usually)  most competive race is roughly 350 miles and goes from Knik Alaska to the village of McGrath Alaska on the north side of the Alaska Range.  Every year a handful of competitors continue along the full length of the Iditarod Trail to Nome Alaska.  This makes for a total of roughly 1100 miles. The route to Nome follows the Iditarod Dog Sled race's pattern of alternating between the Southern Route on odd years and the Northern route on even years.  Currently Jay Petervery holds the record for the 350 mile race to McGrath and the Southern Route to Nome and Mike Curiak holds the record on the Northern route.

A revolutionary concept in endurance mountain bike races, the Iditabike debuted in 1987 outside a small bar near Wasilla Alaska at the traditional start location of the Iditarod Dog Sled Race.  Minimal support, frigid temperatures, no marked course, and a fend-for-yourself philosophy, the Iditabike quickly became infamous in the world of endurance racing, setting the bar for what was possible in human powered races. 
      Though it’s been over 20 years since the last official Iditabike, the name still lives on, recognized around the world as being synonymous with riding bicycles on snow and pushing the limits of human endurance.  This site is intended to pay homage to a great race that not only led to the birth of the current Fat Bike genre, but also inspired cyclists, endurance athletes and adventurers around the globe to rethink what places and conditions are possible to explore by bicycle and provide information for aspiring Iditabikers and endurance cyclists.
