70' Obstacle Course
Nearly twice the length of our standard course — built for events that need a true centerpiece attraction
When the crowd is big and the event needs something that makes a statement, the 70' Obstacle Course is the answer. At nearly twice the length of our standard 40' course, it features two racing lanes, dual climbs, multiple slides, and more obstacles packed into every run — delivering a longer, more intense experience that participants talk about long after the event ends. A go-to for large school field days, church festivals, corporate events, and community gatherings across O'Fallon, St. Peters, Wentzville, and the wider St. Charles County area. Standard 4-hour rentals start at $675.

📏 Why Size Matters at Large Events
When you're running a school field day or church festival with hundreds of participants, the difference between a 40-foot course and a 70-foot course isn't just 30 more feet. It's a fundamentally different experience. The longer run means each participant gets more time actively engaged. The additional obstacles and dual climbs keep the course feeling varied even after multiple runs. And the visual scale of the 70' unit creates a draw that keeps people paying attention to it throughout the entire event.
If you've rented our standard 40' course and been happy with it, the 70' is the natural step up for events where you want to make a bigger statement and keep larger crowds entertained for longer.
70' Obstacle Course FAQs
The 70' Obstacle Course is nearly twice the length of our standard 40' course. In addition to more length, it includes more obstacles, multiple climbing walls, and multiple slide moments throughout the run rather than just one at the finish. The overall experience is longer and more intense, making it the better choice for events where you want each run to feel like a real challenge rather than a quick sprint.
The 70' Obstacle Course requires a clear setup area of 90 feet long by 20 feet wide by 15 feet tall. This is a significantly larger footprint than our 40' courses. Make sure your venue has the open space and check for overhead obstacles before booking.
Standard 4-hour rentals start at $675. Extended 4–8 hour rentals are $810, overnight is $911.25, and weekend 2-day rentals are $1,113.75. Delivery, setup, and pickup are included in every rental with no hidden charges.
The 70' Obstacle Course requires two standard 110V outlets within 100 feet of the setup area — one more than our standard 40' courses. Make sure your venue has two accessible outlets before your rental date.
