Are you ready to take on the Knox Xtreme?
Get ready for an intermediate-level adventure race that will challenge you to run, bike, paddle, navigate, and explore your way through South Knoxville and the Urban Wilderness.
The REV3Endurance Knox Xtreme Adventure Race combines some of the best outdoor terrain Knoxville has to offer into one exciting adventure. You’ll hit the trails, ride through some of South Knoxville’s premier mountain biking areas, paddle your way to checkpoints, and use your navigation skills to find hidden checkpoints scattered throughout the course.
You can race solo and push your personal limits, or grab a group of friends and form a team. Before the race, you’ll receive a map along with the basic rules and instructions you’ll need to plan your adventure.
Then, it’s up to you.
Choose your route. Make your plan. Decide how hard you want to push. Run. Bike. Paddle. Navigate. Find checkpoints. Earn points.
Your goal is simple: collect as many points as possible within the allotted race time. The individual or team with the most points at the finish wins.
But the Knox Xtreme is about more than competition. It’s an opportunity to experience South Knoxville and the Urban Wilderness in a completely different way — discovering trails, parks, waterways, and hidden corners you may never have explored before.
Bring your friends, test your skills, and get ready for an adventure you won’t soon forget.
