Things to Do in Centerville

On a sunny afternoon, kids climb to the top of a giant inflatable slide, kick their feet out, and ride the yellow decline into a ball pit. The merrymakers behind Sumo Party Planners enliven children's parties in just this fashion by renting out inflatable play structures such as bounce houses, obstacle courses, and life-size replicas of The Pentagon. Further amusements range from popcorn machines to face-painting stations. Sumo Party Planners can also combine rentals and services into party packages, with special pricing for schools, churches, charities, and the military.

Equal parts footrace, obstacle course, and mud bath, each RunnerCross course pits participants against up to 15 kilometers of creative and slippery barriers. Runnable as an individual race or as a team relay, heats of 300 runners at a time quickly muddy themselves as they scramble over hay bales, scale rain-slicked hills, and traverse bogs atop a teetering rope bridge. ChronoTrack timing chips in the numbered bibs give runners accurate lap times for settling photo finishes or stacking against past 5Ks, such as George Washington's historic run from a mob of angry cherry farmers.

Part-bike, part-car, and all eye-catching, the Pedal Hopper isn't transit for the faint of heart. This massive vehicle seats anywhere from 10 to 16 passengers at a time as they pedal in unison around downtown Salt Lake City. A company-provided driver sits in the middle, operating the steering wheel and brakes, while guests sitting around the mobile countertop laugh, chat, and exercise their legs to power the vehicle towards custom destinations along a specific route. The two-hour-minimum rides are generally spaced into 20-minute visits with 20-minute pedal sessions, perfect for parties going on a pub crawl or participants on Supermarket Sweep. The Hopper also sports a stereo, disco ball, and LED lights for safe and festive night riding for its 21-and-up clientele.

Designed by U.S. Open champion Johnny Miller, Stonebridge's Scottish-links-style course features 27 holes designed to test your swing and backstroke. The course's namesake red-rock bridges arch over and beside three tough nines, each almost 3,600 yards long, making this one of the longest courses in the state. With 20 of the holes adjacent to water, it's also one of the most pond-besotten. Three smaller teeing areas complement the harder drives, and small streams coil beside some the course's 93 sand bunkers.
