Thumb Coast Ultra & Relay - 50 Mile, 50K, & 50 Mile Relay

Sat April 24, 2027
Caseville, MI 48725 US Directions

Alternate Driving Route

 

We’ve created a custom map in Google My Maps that shows the course, aid stations & exchange points, and the intended driving routes between them.

Crew, spectator, and Relay team vehicles supporting the relay MUST follow the alternative route provided by Trivium.  This will reduce traffic on specific race course to ensure the safety of our athletes.

This is a visual map, not a navigation tool. It shows you where to go, but it does not provide turn-by-turn directions.

Spectator, Crew, & Pacer vehicles may not drive out to Aid Station 4 at the Pointe Aux Barques Lighthouse around mile 19.4.  Only Relay vehicles are allowed here.

Alternate driving route on Google Maps:  https://www.google.com/maps/d/viewer?ll=43.99193170522687%2C-83.29549325673857&z=12&mid=1ESl2ZDZW-Xo0O07M2lkEbAgPa2a0pL4

Important: If you click “Directions” or enter locations into Google Maps, it may route you along the race course. That routing does not reflect our intended driving routes.  Crew, relay, and spectator vehicles should not drive on the race course.

We strongly suggest you save the map for offline use and don't close the Google Maps app on race day.  Cell service is pretty good on the course, but there are areas where you'll lose service.
