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 1,000-mile race to Nome was incorporated into the event as the world’s longest winter ultra marathon by fat bike, foot and ski. Since 2002 the race has continued every year for 15 consecutive years under Alaska Ultra Sport and is now called the Iditarod Trail Invitational.
