St. Louis

Calling all fun-loving St. Louisans! If you want to combine fitness with fun, but are tired of all the conventional 5k runs in St. Louis, you must check out the Xtreme Air St. Louis 5k obstacle course race that’s coming to town on Saturday, June 18, 2016. Not all obstacle course races are created equal. While this Xtreme Air St. Louis 5k obstacle course race is definitely not the most difficult or hardcore of obstacle course races, we’re confident that it is the bounciest and most fun! This race features 12 creative inflatable obstacles spread out over a 5k course, and is appropriate for a wide range of ages and fitness levels. Visit our obstacles overview page to learn more about each of these 12 bouncy obstacles.

Whether you want to seriously challenge yourself and see how fast you can complete the course or your number one goal is to have fun, this is the one St. Louis 5k race you don’t want to miss out on.

On Saturday, June 18, 2016, the Xtreme Air St. Louis 5k inflatable obstacle course race will be held at Forest Park, a beautiful, natural oasis in an urban environment and the seventh largest urban park in the country. Forest Park is located at (click here for directions).

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.

On race day (Saturday, June 18, 2016), if there are any open spots left, we welcome race day registration in any open waves. We encourage you to pick up your race day packet, which includes your race bib and wave wrist band, on Friday, June 17, 2016 (time and location to be announced). If you choose to wait until race day to get your race day packet, that’s okay too—but just be sure to arrive an hour before your starting wave time so you have adequate time to deal with traffic, parking, and registration check-in.. Important: whether you pick up your race day packet on Friday or on race day Saturday, you must bring your photo ID to check-in.
