Hey there, Tennesseans! If you’re going to be in the Knoxville-Sevierville-LaFollette area on April 30, 2016, then clear your calendars right now! For the absolute best time, participate in the Xtreme Air inflatable obstacle course Knoxville 5k run. Sure, there may be 5k races near Knoxville nearly every weekend of the year, but I can guarantee you no Knoxville 5k run will be anything like this Xtreme Air 5k race.  We are not your average run!

This Xtreme Air 5k custom obstacle course features 12 inflatable obstacles spread out over a 5k course at the scenic Chilhowee Park & Exposition Center, located at 3301 East Magnolia Ave. (get directions here).  Each unique, inflatable obstacle (some more than three stories high!) will excite and challenge race participants—sending the fun level soaring to new heights! You truly have to experience it first-hand to appreciate the epic fun and creativity of the event!

This race is ideal for all ages and fitness levels. While there will be plenty of opportunities to challenge yourself or get a little competitive with a teammate, Xtreme Air 5k participants don’t have to worry about who is the fastest, strongest, or most agile. The Xtreme Air Knoxville 5k run obstacle course is not about showing off superhuman acts of fitness, leaping over fire pits or electrified wires, or setting a new race PR. You just have one goal: to HAVE FUN!

Don’t miss out on all the excitement! This may be the only time the Xtreme Air 5k race is in your area; also, the race usually sells out before race day, especially for the most desirable starting time waves. Reserve your spot today, using the quick and easy online registration system with As an added bonus, the earlier you sign up, the bigger your discount on registration fees. Also, make sure to check out all our other race locations for the year. If you don’t see an Xtreme Air 5k race near you, click here to suggest a new event location.

Interested in Volunteering?

Be part of the Xtreme team! Our courses require a lot of man power to run smoothly and we couldn’t do it without our volunteers. Not only will you gain entry into a race (and get a cool T-shirt), but volunteering at one of our events is a great way to take care of community service hours or support family and friends participating in the event.
