Wednesday Night Mountain Bike Race Series #1
About this race
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.
