Thumb Coast Ultra & Relay Race Description

Race the Sunset in Caseville, Michigan!

The Thumb Coast is a hidden gem in Michigan. Don’t miss the 2nd Annual Thumb Coast Ultra & Relay for a unique experience to run from "sunrise to sunset" from "one coast to another" on Saturday, April 26, 2025. 50 Milers race from Harbor Beach's Lake Huron to Saginaw Bay in Caseville! Can you make it to the finish line before sunset?

This amazing route follows mostly dirt roads through the thumb. 50 Milers and relay teams start in Harbor Beach and the 50K starts & finishes in Caseville. This event is perfect for beginners, seasoned vets, and those looking for a personal best. The course will be extremely well marked with great aid stations along the way! We have generous cutoff times, and additional prizes for 50 Mile ultra finishers who "beat the sun" at Thumb Coast Ultra & Relay.
