The Coast to Coast gravel grinder will not be known for just its gravel (actually more dirt than gravel), ironically, but for everything that’s NOT gravel – the forest roads, the two-tracks, the snowmobile trails, even a little gravel-friendly singletrack. Much of the second half of the course is heavily forested, with winding two-tracks, constantly changing. It’s a challenging roller coaster ride. Set your eyes on the glorious sunset over Lake Michigan or ride into the night to get to the finish line on time.
- Date: Saturday, June 24, 2023
- Start: Point Au Gres Marina, Lake Huron

This is a simple race. No fanfare at the start. No cheering crowds along the way. No fancy finish. It’s just you, your bike and a strip of dirt winding its way from one freshwater sea to another.
Except it’s not just you. The rider next to you shares that he just beat cancer and this is his victory ride. And another helps you with a mechanical. And then you open up to a stranger about your life and why you are doing this race. And you bond with your amazing support crew who are helping you achieve your goal. This isn’t a simple race. It’s a memorable, powerful experience.
Bicycling Magazine’s Selene Yeager captures the essence of this experience in her ode to this race.
We’ve teamed up with top Midwest endurance racer Matt Acker, co-course designer, who knows Michigan’s gravel roads and gravel racing better than anyone, to create a course you will be sure to love. You’ll never forget the sunrise start on Lake Huron and the “ecological + elevation bell curve” journey westward through farmland, wetlands, pine barrens, rolling uplands and magestic forest and then back down, toward the amazing sunset over Lake Michigan. Finish your race in one of the great outdoor towns in the country, Ludington, touching the waters of Lake Michigan and completing your amazing adventure. Ludington provides an ideal finish town for venues, lodging, breweries and love for the outdoors.
Our design philosophy is to provide the best combination of scenery, dirt surfaces, safe roads and fun riding while minimizing sandy sections and paved and/or higher traffic riding (you’ll see very few vehicles on the course). We will do our best in the weeks leading up to the race to alert you to road surface conditions as they can change fairly considerably depending on recent weeks of rain or drought before the race. When in doubt, go with wider tires and bring extra water. Riders never regret this.
I arrive at the finish a better person. – Rebecca Rusch, world champion mountain biker (and gravel road lover)
Finish Rates (2018-2022)

The normal finish rate in temperate weather for the 204-mile race is 85%. 2021 was the infamous “monsoon” year and 2022 had abnormally high temperatures.
SWAG & Finisher Awards
- All 204-mile and 100-mile racers will receive a Coast to Coast shirt or SockGuy SGX racing socks plus your choice of a water bottle, leather key chain, or Orange Mud buff/neck gaiter!
- 204-mile finishers will also receive a sticker/decal, a commemorative stem cap, and pick from either a “finisher” tumbler, beer barrel mug or more socks.
You must have a rescue/support person or crew in your general vicinity throughout the race, either our paid service or your own. They do NOT need to be present when you arrive at the three checkpoints. They may NOT meet you out on the course, consistent with many similar endurance gravel races with a self-supported ethos.
Why do we use the word “rescue”? Let’s say there’s unexpected severe weather and 50-100 bikers need to quickly be removed from a dangerous situation or the race has to be cancelled. Or it’s a day of record heat and 30 bikers need to drop out. How do they get to Ludington? That’s the job of the rescue/support crews. Note that the Big M checkpoint requires a $5 daily use fee per vehicle (self-service kiosk).
No bike or wheel swaps are allowed during the race. See the Rider’s Guide under More Info for all the rules and more.

If you’d like to experience the crossing of Michigan with a friend, you can each bike half of the route and drive the support vehicle the other half (keep in mind the support vehicle can only meet the racer at each checkpoint). You must switch at a checkpoint and you must each do any two of the four sections.

- There will NOT be signs on the course except posts with streamer tape at two-track and snowmobile trail intersections where clarity is helpful. See the Route page for details.

Our charity partner is the Juvenile Diabetes Research Foundation (JDRF), the only global organization with a strategic research plan to end type 1 diabetes (T1D), a serious autoimmune disease that affects millions of children and adults. Type 1 diabetes has nothing to do with diet or lifestyle, and there is nothing you can do to prevent it. Currently, there is no cure. It requires constant carbohydrate counting and blood-glucose testing, and lifelong dependence on injected insulin. But insulin is not a cure, and it does not prevent the possibility of serious complications such as kidney failure, blindness, and stroke. With your help, JDRF’s vision of a world without T1D can be achieved! Visit their website.
