The 24 Hours of Riverside is a 24 Hour Mountain Bike Race taking place Memorial Day Weekend 2024 at Riverside State Park in Spokane WA.  But there's so much more!  It will be a weekend of riding and camping and fun that you will never forget!  Race starts at High Noon on Saturday.  There will be food and beverage options on-site at different times throughout weekend. Camping on-site as well.  And don't forget the Kid's Bike Parade Saturday Night!  So much fun in 24 hours, you'll be sad it's only 24 hours!

This year, Washington State Parks is going to charge for camping at the airstrip for the weekend.  Each "campsite" will be $12 per night, and includes one vehicle (no matter what size).  Additional vehicles that are staying overnight, are $10 per night.  If you are paying for camping, or extre vehicle, you DO NOT need a Discover Pass.  Anyone coming in for just the day, any of the days, will need a Discover Pass.  

There is no way to pay for camping online.  Yeah, we know....it's 2022/23 and you would think....but alas, camping will be paid for on-site.  A Ranger will be onsite during friday evening packet pickup that you can purchase camping from.  THIS WILL BE THE ONLY TIME YOU CAN PAY WITH A CARD.  The rest of the time, there will be payment envelopes that you can stuff with cash or check, and take to the payment drop near the trailhead parking lot.  

Thank you in advance for your patience with this.  This is 100% a Washington State Parks thing.  And also up to them to manage.  We are sorry for the added cost, but there's not much we can do about it.
