From the Organizer
2026 is the first year of our 3rd decade of racing!!!!. 21st year of racing on Wednesday Nights in May and June. Thanks to all who have raced with us over the years! If you are new to our Series of Wednesday night fun, welcome!!
This is a race series for EVERYONE! As long as you have a bicycle worthy of being ridden on dirt, and can pedal it, you can do this! If you are a pro, it’s great for training. If you are new to Mountain Biking and/or Riverside State Park, it’s a great way to learn the trails and make new friends.
We use the term “race” loosely. We are all about fun and keeping it simple! Come out on Wednesday Nights and ride your bike. Pedal as hard as you want or casually if you want. If pedaling casually, do keep in mind that it will eventually get dark! New course every week. Random prize drawings and cold drinks will be waiting for you at the Finish Line.

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
Mountain biking takes place on singletrack and natural terrain where reading the trail matters as much as fitness — cornering, braking, and instinct on dirt are skills that only come from time in the saddle.
Events range from beginner-friendly cross-country races to technical enduros, and the trail community is one of the most welcoming in endurance sport.
XC races, enduros, and fat bike events across Midwest trails. Technical, physical, and completely different from anything on pavement.
