210 Mile Race Details

The Coast to Coast gravel grinder, presented by Salsa Cycles, will not be known for its gravel (actually more dirt than gravel), ironically, but for everything that’s NOT gravel – the forest roads, the two-tracks, the snowmobile trails. Much of the second half of the course is heavily forested, closed in, 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 26, 2021 (Oct. 3, 2020 race was canceled)
  • Start: Point Au Gres Marina, Lake Huron
  • Finish: Stearns Park Beach, Ludington
  • Distance: 208ish miles
  • Duration: 21 hour cut-off

The Experience
This is a simple race. No fanfare at the start. No cheerling 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. 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 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 journey westward through farmland, wetlands, pine barrens, rolling uplands and magestic forest, 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.

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

Ludington provides an ideal finish town for venues, lodging, breweries and love for the outdoors. Race Central for awards will be the historic Stearns Hotel, built in 1903 by lumber baron Justus Stearns and located downtown, near the finish and great breweries and restaurants. So that later finishers can join for the awards and raffle, we’ll hold it Sunday morning.

What Do I Get?

  • All 210- and 100-mile racers will receive a Coast to Coast water bottle
  • 210-mile and 100-mile registrants will also receive the race shirt or socks (women’s size/cut available)
  • All checkpoints will be chip timed, along with the start and finish. Spectators can track your best-guess location with average speed tracking.
  • Check out the finisher awards and top finisher prizes here.

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. 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. Details on the two options:

Two-Person Relay
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.

Route Finding

  • 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.

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 websites: http://www2.jdrf.org or  http://greatlakeswest.jdrf.org/
