De Ronde van Grampian
(This event is organized by a CRAMBA partner.)
The De Ronde van Grampian is now part of the Michigan Gravel RACE Series with its roots derived from special races and rides from years past in and around the local area of Oakland and Lapeer Counties. This ride pays tribute to the Ronde van Stony, Grampian Challenge and Fall 50. For 2026, The De Ronde van Grampian will be held on Saturday August 1st starting and finishing inside Upland Hills Farm.
There will be three distances: 12-mile, 25-mile and 50-mile courses consisting of 100% gravel. These routes travel through the natural rolling terrain in the area with amazing scenic views and a special single and double track mixed in for good fun! There is even a Dutch Windmill out on the 50 course! We will provide marked routes, .gpx files, along with timing provided by Epic Timing, along with free beer (while it lasts). Food will be available for purchase after the race.
Get more info here at the race website.
Shelden's Big Bang
(This event is organized by a CRAMBA partner.)
Racing is back at Stony Creek!
Mashing up exciting machine built single track, an old school climb trail, and classic two track, an 8.5-mile lap is on tap for racers at Shelden's Big Bang! Push hard and try to get that top step, beat your friends, or push yourself in your first mountain bike race on some of Southeast Michigan's favorite trails.
After the half-mile hole shot and prelude from the start line, the remaining 8 miles (split 60/40 between single and two track) features 6 unique single and two track sections per lap, perfect for testing your handling and having fun while offering wide-open, fast, safe areas to pass. Steady climbs, flowing descents, and lots of fun and excitement await!
Get more info here at the race website.
Addison Oaks Summer Classic
(This event is organized by a CRAMBA partner.)
Classic XC racing at the incredible Addison Oaks County Park.
Get more information here at the race website.
Tuesday Night River Bends Ride
Join CRAMBA on (most) Tuesdays throughout spring, summer, and fall for a group ride at Shelby Township’s River Bends Park!
We meet in the public parking lot behind the Fire Department in downtown Utica at 6:30pm, with the ride departing at 6:45pm, sharp (map).
The ride is dependent on weather and trail conditions and loosely organized; please don’t be offended if you show up on an iffy day and no one is there. Basically, if the trails are muddy, we don’t ride. But on nicer days we’ll often have 30+ folks joining us to have fun on bikes in the woods. (Ride updates are often posted on the CRAMBA Facebook Page or Clinton River Area Mountain Biking Facebook Group.)
Depending on attendance we may split into multiple groups, with the A group riding a bit faster and stopping a bit less than the B group. But don’t worry, no matter which group you’re with, no one gets left behind. (This is a fun ride, not a race.)
We head into the park via the paved path from Utica, starting at that end, and typically ride one full lap of the beginner and intermediate single track trails on the east side of the river, for a total of about 10 miles. Sometimes the A group will add on the more advanced Spring Hill and Robbins Ridge trails on the west side of the river, but this depends on how the group is feeling that night.
Class 1 Pedal Assist eBikes are welcome (no throttles), and helmets are required.
If you need toilets or water before the ride they can be found either at Pioneer Dog Park or in Utica City Hall.
See you there!
(And sometimes folks go for tacos at Mr. Miguel’s or burgers at Shamrock afterward.)

Massive Fall Out
IMPORTANT: VENUE CHANGED FROM ADDISON OAKS TO STONY CREEK
Save the date! Massive Fall Out is coming back for another year of good friends, good trails, and good vibes. As in the previous few years, we’ll be starting from Stony Creek and the ride will include some of your favorite trails like Bald Mountain.
One notable change this year is that we’re forgoing the mass start in favor of a finish line party. Each rider is welcome and encouraged to start at any time in order to be at the celebration. Finish line party is from 1 to 3pm, so plan your ride accordingly.
There will be a few suggested routes, but keep in mind these are only suggestions. Feel free to add or subtract as you see fit to challenge yourself.

Massive Fallout
Massive Fallout is a large-scale group ride organized by the volunteers of the Clinton River Area Mountain Bike Association (CRAMBA-IMBA).
The main route features four CRAMBA trails: Addison Oaks, Bald Mountain, Orion Oaks, and Friendship Park. For those looking for a shorter option, a route with only Addison Oaks and Bald Mountain is available, while those looking for an epic day in the saddle have the option of the long route which includes the full main route as well as Stony Creek Metropark. These trails are all connected via a series of roads, paths, and rail trails, creating a fun, flexible ride. Whether you’re a beginner or expert, the ride can be configured to your experience level and desired length. See below for route details.
Maps will be available before the event. Join us for the mass start to be part of one of the largest mountain bike group rides in Southeast Michigan. If you aren’t familiar with the area, hop on with some of your fellow riders to show you the way.
This ride is a CRAMBA event and will be insured under the CRAMBA group event policy. An aid station will be available during the ride.
Location: Start and end at the Trails Edge Pavilion at Addison Oaks County Park
Ride Cost: Free! (purchase of Addison Oaks day pass may be required), however there is an optional donation during checkout. If you enjoy these events and want us to continue putting them on, please consider donating. You will need to pay for parking at the park.
Registration: https://www.bikereg.com/mfo-2024 Please register through Bikereg. There is no cost and it helps us with planning, insurance, waivers, and other event details. We will also be sharing details such as routes and event updates through Bikereg. Signing up for a specific route does not obligate you to do that route, but just helps us know how popular each route is.
Routes: This year there are 3 routes. The main route is ~45 miles and covers all or most of Addison Oaks, Bald Mountain North, and Friendship Park single tracks, as well as parts of Orion Oaks County Park and Bald Mountain South. Parks are connected by sections of road, Paint Creek Trail, and Polly Ann Trail. For those looking for something more relaxed and approachable, the ~25 mile short route cuts out Orion Oaks, Friendship Park, and most of the road sections. Finally, for those looking for a truly epic day, the long route adds an additional 25 miles to the main route for a total of ~70 miles, including a significant Paint Creek Trail section, Gunn Road, Bear Creek Nature Park, Snell Road, Shelden Road, and most of the Stony Creek single track. GPS routes for all 3 options coming soon. If any of the above routes don't appeal to you join us anyway and choose your own adventure!
