Join us for a Colorburst 40th Anniversary Celebration on Saturday, October 14th, 2023! Ride founder Craig Campbell originally started the memorial ride from Chief Hazy Cloud Park in Ada, and we shall do the same. There are 3 routes from which to choose. A scenic 50 km (31 mile) road route to Fallasburg Park and back, then two 100 km (62 mile) routes through Fallasburg Park, then up to Belding and Greenville and back. The Road 100K route is all paved, while the Adventure 100K route includes gravel and bike paths. Registration and ride start is from 9am till noon. We will be providing coffee and doughnuts/pastries at the start, and firing up the grill about noon upon your return. This is largely a self supported ride with very limited on-road support. Riders should be able to carry some of their own hydration and nutrition and repair their own flats. However, there are several possible stops for food & hydration, as well as restrooms, along the route.  

Ride maps on paper with turn by turn cue sheets will be available at the ride start. The routes are NOT marked. 

Routes on Ride with GPS for downloading routes and turn by turn directions for device navigation are here:

Colorburst 50K Route 2023 

Colorburst Road 100K Route 2023

Colorburst Adventure 100K Route 2023

The Adventure 100K route includes about 37% gravel roads and should be ridden with wider tires. We recommend a gravel, fat tire, or mountain bike with at least 32mm tires. The descent to White's Bridge is on steep gravel, but the reward is seeing one of the few covered bridges in West Michigan. The route then rewards the rider with a spectacular view of the Flat River Valley up to Smyrna.  

The ride is FREE to Rapid Wheelmen club members. For $35/yr per family, you can ride all our rides at a discount and ride for free on weekly rides and our Ada Time Trials. New memberships late in the year are good for the following year too! We will accept any cash donations for a charitable cause.

For non-members, the fee is $10 cash per rider day of event. You'll also need to sign our waiver form. 


Colorburst was started in 1983 by Craig Campbell, a Rapid Wheelmen member, as a memorial to Donna Ryskamp, who was killed on August 9, 1983, by a drunk driver while bicycling. Craig Campbell was killed when a drunk driver struck his motorcycle on August 29, 1987; Craig was driving the route for Colorburst before printing the map for the ride. Now in its 41st year, Colorburst continues to honor Donna and Craig, and has raised more than $100,000 for Mothers Against Drunk Driving (MADD) and other local charities. (More Colorburst History)
