Check In
Use the form below to check in. Check-ins must include a photo of you or your bike at the challenge site with the 2026 bandanna. All participants must be registered IAMC Challenge Members. Leave a description of your ride and share road conditions — snow, water, obstacles, and tips for future riders are all appreciated.

The stated difficulty is an estimate. Rating your experience helps future riders stay safe. You alone are responsible for the safety of your ride.
