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.


Every Wednesday Night in May and June, starting May 3rd. Registration opens at 5PM. Racing starts promptly at 6:30 PM.


The “old airstrip” in the 7 Mile Area of Riverside State Park.

Directions from the intersection of Assembly/Francis/Hwy 291: Follow Hwy 291 North. Turn left at 7 Mile Road (there are signs). 7 Mile Road until you cross the bridge over the river and then take the first left. From there you are just a few minutes away from the fun, follow the signs leading you to the parking area.


$20 per race for 18 & Over. You can pay with a credit/debit card onsite, but it will cost you an additional $1 to cover the credit card fee. Register for the whole series in advance and save some money. Register online here: https://www.athletepath.com/wednesday-night-mtb-series/2015-05-06 or onsite the first night, May 3rd. ALSO, you are required to have a Washington State Park Discover Pass to park in the park. $30 gets you a pass for an entire year for 2 vehicles. **A one time fee of $5.00 will be charged in addition to your registration for your number plate and timing chip. Number plates and timing chip included with Series pass purchase. This is yours for the season. Replacements are $5.00.

17 and under are paid for by various sponsors.  If you are on one of the High School/Middle School Teams, you must fill out the correct entry form for your fee to be paid. All other 17 & Under will have to register at each race, and those entry fees are already paid for as well.


The race will be timed and scored using chip timing from Nomadz. Results will be posted as quickly as possible after each race. You will be issued a number plate with a timing chip stuck to the back of it. It is yours for the entire series. Please hold on to it, and try not to ruin it. Replacement number plates/chips will be $5.00.


2017 marks our 12th year of racing on Wednesday Nights. Our main goal is fun. Part of the fun is keeping things simple. We don’t have a bunch of age groups, multiple start times (although reserve the right to break groups into separate start times for safety reasons) etc. We have a different course each Wednesday that will challenge you in different ways. You will have the option of going 1 lap or 2 laps. Laps are typically 7-11 miles. The only “age groups” we do have are 14 & Under (Male & Female), 15-17 (Male & Female), 18-39 (Male & Female), 40-49 (Male Only), 40+ (Female Only) and 50+ (Male Only). Your age group will be determined by the age you are on the first night of the series. We will keep points for the entire series. Division Winners get prizes at the final party.

**Junior Age groups will be broken down to 14 & Under and 15-17; 1 lap for Male and Female. There will be a 15-17; 2 Lap, Male only.

Post Race:

Each night is sponsored by a different local bike shop. There will be a random prize giveaway after every race. Also, ice cold beverages for all to enjoy (please, one per person until most everyone has finished).

Please show up and be registered no later than 15 minutes before race start. Start in the correct wave for your distance and age group. Not doing so throws off the results and you may be DQ’d. The race is timed off the “Gun” start, and not the chip. Don’t hang back thinking your race starts when you cross the mat. That is not the case. On course: please be respectful of other park users. We have a permit to race on the trails, not to close them to others. Be careful of your fellow racers. Don’t run over the top of slower racers. And if someone is injured, please stop to help if necessary.


We strive to leave the area better than we found it when we came in. Please pick up any trash you find, whether it’s yours or not. Also, please be kind to the neighbors that live near the park. Go very slow on the road on dry warm nights to help keep the dust to a minimum.
