The holy grail of winter ultra events, the Iditasport was the world’s longest winter fat bike and running race. Inspired by Joe Redington Sr. and brought to life by Dan Bull, this human-powered event was first held in 1987 as the Iditabike, a 210-mile mountain bike race.
In 1997, a 350-mile race to McGrath, Alaska was added as the Iditasport Extreme, and in 2000, the Iditasport Impossible, a 1000-mile race to Nome was incorporated into the event as the world’s longest winter ultra marathon by fat bike, foot and ski.
In 2002, racers Bill Merchant and Par Irwin replaced the original Iditasport race with a new version of the event, the Iditarod Trail Invitational.
The “Thin White Line” a documentary film by RJ Sauer (Brudder productions) cronicles the last year of Iditasport 2001.
The Iditarod Trail Invitational has been held every year since 2002. The 2018 race starts on Sunday, February 25th at 2:00pm. For more information, visit the Iditarod Trail Invitational website.
