Name: Rob Grunnagle

We recently interviewed local Oz Trailer, Rob Grunnagle of Ozark Cycling Adventures. Check out his Q&A below!

How long have you been riding? I started mountain biking back in 2000 after I broke my collarbone and gained about twenty pounds due to inactivity. I thought riding a bike would be a great way to get myself going again. Who knew I would fall in love with it and ride almost 5 days a week for the last 16 years!

What’s your favorite Oz Trail? Oh man, depends on my mood! Right now I’m really digging The Back 40. It is still so new and unexplored in my mind. Kessler for the days that I really want to be challenged on the bike. I like riding it with folks who are better bike handlers than me. It’s fun to try and keep up and get pushed out of my comfort zone.

Camp out or cabin? When I was younger camp for sure. Now that I’m older and more established splitting a cabin with my closest buds is the ticket. But for the most part, I’m lucky enough to walk out my door and jump on the bike and ride some of these incredible trails!

Tire size? Right now I’m running 29er’s with 2.4’s. I’m on a super light XC hardtail so I use the added tire volume from the 2.4’s for grip and I really like to run low pressure for added suspension.

Dream place to ride outside of Arkansas?New Zealand. One of the most wonderful and beautiful places I’ve ever been to. I didn’t ride on that trip because I was too busy trying to get engaged to my wife! Now I need to go back to ride!

What are you most excited about happening during the IMBA World Summit?I am most excited about helping folks traveling here for the summit to have a great experience on the Oz Trails. I love where I am from and really excited to have opportunities to share that with everybody!

OZ Trails community,

When I think about where this started, trail builders like Dave Renko, Nathan Woodruff, and Don West from the early days come to mind. They strengthened my belief in the power of trails and in Arkansas becoming one of the great places in the world to ride. It started simply: a few hand-built trails, a lot of conviction, and a community willing to put in the effort to create something special.

OZ Trails was never just about bikes. It was about building a way of life around the outdoors — a place where families spend more time together, where people find clarity away from screens, and where visitors feel welcome. It proves that something world class can still feel local, personal, and rooted in the land.

For years, we dreamed about this park. We walked the land, studied what it could become, and kept coming back to the same idea: Northwest Arkansas deserved a bike park that matched the ambition of this community.

Now, we’ve built it.

OZ Trails Bike Park is where so much of that work comes together. It was created with trail builders who treat their work like a craft, supported by bike patrol so riders can feel confident, and shaped by a team that cares about the experience from the moment you arrive. I've been riding the park throughout development, and I finish every ride believing it will change how people progress and connect with each other.

Founding Membership is an invitation to the people who get it — the riders who know what time on trail does for you: clearing your head, building confidence, finding your people, and feeling a sense of pride in the place you ride. We want you here from day one. Membership is more than access. It helps set the tone for what this park becomes. The first members should be people who care about the culture, who welcome others in, and who believe this place can keep growing into something truly special.

As a father, I often think about watching my kids progress on these trails — starting on green, moving to blue, and then deciding they’re ready for black. It’s part of why we built this place the way we did — so families can show up, everyone has something to ride, and they can keep building the skills to take the next step.

Alongside Founding Membership, we’re also launching a Founding Family Membership for those who want to share this with the people they love.

Our Founding Memberships open today.

Come ride it. This place was built for you.
