Crystal Rush Mountain Bike Race

Want to lower race costs? Volunteer!

At most Tris4Health and Boundless Race & Ride Company events, volunteering earns vouchers for future races. Choose a shift, register, and rack up vouchers—values depend on the role, and you can combine them at checkout.

You have a lot of racing shirts.  Don’t need another one?  Select the shirtless option during the registration process to save $5.  It’s not much, but it all adds up!

Do you have friends?  Do they want to race?  Refer 5 people to the race and we will refund you $20 automatically.  It’s as simple as that.  For instructions on how to use your referral links, please follow these instructions.

Ages 11 and under for $25, no tiers.

Ages 12-19 race for $35, no tiers.

We love seeing young athletes jump in—even when they’re faster than us. If you can, please register early; it helps us plan and avoid over-ordering swag.

Please note, kids 11 and under must be accompanied by an adult who can register for free by reaching out to us at: info@boundlessrr.co.  The adult MUST register to be allowed on-course.  If you are part of a team please let us know as it doesn’t need to be one-to-one adult to child.  If you have a couple of people who want to sweep a team of kids we can make that work.  

Riding is better with friends!

Reach out for a team discount if you’re bringing a group of 5 or more!  For full details of our team program, please visit this link.

Racing costs are up—you feel it, we do, too. If pricing is out of reach (job change, big family, waited too long to sign up, whatever), tell us what you can afford—even if it’s $0—and we’ll work something out. No judgment, no questions. We believe people are good and sometimes need a hand. We do reserve the right to limit free or reduced entries, but we’ve offered this for years at The Dirty Mitten without issues.

• Early Bird (12/10 – 12/31)
• Tier 1 (1/1 – 2/8)

“Boundless Race & Ride Company” is a new cycling-focused brand under Michigan Endurance Holdings, LLC, which also owns the “Tris4Health” brand.

Since its inception in 2019 with two multisport events, Michigan Endurance Holdings has grown to produce over 20 events each year. All our cycling events are organized under the Boundless Race & Ride Company brand. We maintain the same team and standards as with our Tris4Health brand, but with a specific focus on races and rides featuring two wheels.

The Elite category is designed for riders who want to test themselves against the strongest field in the Boundless Race & Ride Company Grand Prix. To earn series points toward the Elite title, you must register in the Elite category at each event. We’ve mixed in select race distances across the series to reveal the most complete, all-around cyclist.

• Swag Item (TBD. For Peak2Peak 2025, riders received a Specialized water bottle)
• Free entry into the Boundless Race & Ride Company Grand Prix
• Customized (small!) number plate with chip timing by SportStats
• Well-marked course with volunteers and police at pre-determined intersections
• Aid Stations (depending on distance)
• Killer awards and prizes

New for 2026: We’re standardizing award categories across every race. Age-group awards will now be in 5-year increments for men and women at all distances. We’re also recognizing Clydesdale, Athena, Single Speed, and Fat Bike across every distance.  Age groups will be based on your age at the end of the year to keep things consistent across all events for scoring.

Awards go to the top three in each category—except Elite, which recognizes the top five.

Looking to race at the sharp end? The Elite wave is designed for our most competitive athletes. Expect prize money at every event, plus a larger cash purse for Elite racers at the Grand Prix.

We make every effort to have our courses set well in advance of the race. However, we reserve the right to adjust the courses, number of laps, etc., depending on rider feedback prior to the event, weather, etc.

In the event of an emergency or if we need to communicate important information on event day, please stay tuned to our social media accounts on Facebook and Instagram, as well as your email and venue PA announcements.

Upon finishing, athletes can expect to receive bananas, oranges, cookies, and chips at the post-race food tent. Gatorade and water will also be distributed.

Our friends at Crystal Mountain will have food and beer available for purchase as well.

We are projecting an 80′-90′ cutoff for each race.  If you fall too far behind you could be pulled.

The weather can vary significantly from year to year, with an average low of 43 and a high of 60.

This event is held at Crystal Mountain in Thompsonville, MI.

Crystal will be offering great deals on lodging, spa packages, and more.  Coming soon!
