204 Mile Race Details

Koon road in Manistee National Forest

The Coast to Coast gravel grinder is not known for just its plentiful 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 22, 2024
  • Start: Point Au Gres Marina, Lake Huron
  • Finish: Stearns Park Beach, Ludington
  • Distance: 204 miles

The Experience
This is a simple race. Just a small fishermen’s village at the start to cheer you on. A spattering of cheering folks along the way but no big crowds. No fancy finish (although Lake Michigan is more spectacular than any grandstand). It’s just you, your bike and a strip of dirt winding its way from one freshwater sea to another…

Racers on gravel road on courseExcept it’s not just you. The rider next to you shares that he just beat cancer and this is his victory ride. And another is more than willing to help you with a mechanical despite encroaching darkness. 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.

Course Design
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 a similar curve, toward the amazing sunset over Lake Michigan. Finish your race in one of the great outdoor towns in the country, Ludington, touching your front tire to the waters of Lake Michigan and completing your amazing adventure.

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). Depending on drought conditions and ORV traffic which is now allowed on US Forest Service roads, there will be some stretches of sand so we recommend going with the widest tire you can on your bike, particularly if the course does not receive much rain in the weeks leading up to the race. Those who ride at or wider than 44mm or 2″ get through the sand well. 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 rain, drought and ORV traffic before the race. In 2023 we added a neutral water station half way through the most difficult section but we still recommend maximizing your water at each checkpoint and taking advantage of the trail angels along the way (but not depending on them).

I arrive at the finish a better person. – Rebecca Rusch, world champion mountain biker (and gravel road lover)

Rescue/Support Crew
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.

bikers in Manistee National ForestWhy 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.

No bike or wheel swaps are allowed during the race. See the Rider’s Guide under More Info for all the rules and more.

Weather Averages

  • Average temp at start, Au Gres, 6 am: 55 degrees. Primary temp range: 65-75 degrees. Average temp at finish, Ludington, 60-65 degrees
  • We experienced abnormally warmer temps the last two years so have a conservative pace and hydration plan if that’s the case again.
  • Cloud cover is typical and heavy shade in the Manistee National Forest (during peak sun; miles 130-190)
  • Wind direction: 67% of time wind is NOT out of the west in late June
  • Average wind speed: 6-10 mph during day (less early am and late pm)

Two-Person Relay
If you’d like to experience the crossing of Michigan with a friend, you can each bike two separate legs as a relay, handing over your race number/bib (with timing chip) at a checkpoint. The teammate who is not biking, drives the support vehicle to the next checkpoint (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 two of the four sections; one person can do two in a row if desired. Keep in mind that section 3 is the hardest and the longest. You each use your own bike.

  • Course directions are via GPS tracking file (gpx/tcx on Garmin, Wahoo, Strava, etc.) and cue sheets. ALL riders must have at least cue sheets.
  • 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.

See the Lodging page for options for both Friday night in the Au Gres area and Saturday night in the Ludington area.

Charity Partner
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.
