Iditarod Trail Invitational

The Iditarod Trail Invitational (ITI) takes riders deep into the Alaskan wilderness along the historic Iditarod Trail, combining extreme distance, winter conditions and near-total self-reliance. Competitors travel by bike, foot or ski, carrying the survival equipment they need to deal with one of the most demanding endurance environments in the world.

For cyclists, the ITI offers three distances: the 150-mile ITI 150, the 350-mile ITI 350, and the 1,000-mile ITI 1000. The 150 finishes at Rainy Pass Lodge, while the 350 continues to McGrath. The full 1,000-mile route follows the trail all the way to Nome on the Bering Sea.

The route begins near Knik Lake outside Anchorage and crosses some of Alaska’s most remote terrain, including the Alaska Range and long stretches of wilderness between isolated villages. The trail is not marked, and conditions can range from deep snow and glare ice to mud, blizzards, extreme cold and gale-force winds. In the 1,000-mile event, riders must be prepared to cover the final 500 miles with no race support, relying on what they carry and supplies sent ahead to remote villages.

The ITI is built around self-reliance rather than conventional race support. Checkpoints provide food and minimal lodging, but riders remain responsible for navigation, winter camping and survival in an environment where conditions can change rapidly. The 2027 edition follows the southern route of the Iditarod Trail.
