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.
Replying to another person's check-in is encouraged, but take care not to accidentally create your own check-in.
The stated difficulty is an estimate. Rating your experience helps future riders stay safe. You alone are responsible for the safety of your ride.
