The Inaugural Oz Trails Off-Road allows participants to choose from the Ozark 25, Ozark 35 and Ozark 50 graduated route options. While "Ozark" pays homage to the Oz Trails network, each number represents the distance of each route in miles (+/-).

All three routes will challenge riders with varied rolling terrain connecting world-class purpose-built singletrack for mountain biking in the beautiful and rugged Ozark Mountains of Northwest Arkansas.

Boasting more than 200 miles of trails connecting communities, Northwest Arkansas has become one of the hottest new mountain bike destinations in America thanks to more than $30 million invested into trails development over the last five years alone. The Oz Trails Off-Road will celebrate this community investment by taking participants on numerous featured trails, including the Slaughter Pen trail system, the Back 40 trail system in Bella Vista, and more.

The Ozark 35 challenges riders with 4,475 feet of climbing through a succession of short, punchy climbs that gradually tax the legs and lungs. With the same mass start rollout to the Ozark 25, once into the Back 40 area, Ozark 35 riders will experience more of the Back 40 Loop.

Riders will then get to experience Flo Ride, an icon of the region delivering technical downhill flow with numerous features including berms, jumps, small rock gardens and limestone ledges that will spice up the ride.

From there it's onto Rago and into Slaughter Pen just like the Ozark 25, but taking Tatamagouche trail, rich with wooden features and rock armoring, working over arms as well as suspension before finishing the same way as the Ozark 25 via the legendary A-line bike to school route included in Ozone trail.

Word on the street is that Arkansas has an exploding riding scene, so I finally visited to see it with my own eyes. But I wanted to not just ride...

Perfect conditions. Just enough moisture to make the trails grippy. Only a couple small puddles along the way. No down trees.
