The SPRING SPRUNG 5k-10k and Half Marathon

Lace up for a vibrant start to spring at The SPRING SPRUNG 5k-10k and Half Marathon, taking place on May 16, 2026, in the scenic St. Louis area. Hosted by Rockinator Racing, this popular event offers distances for every runner, including a 5K, 10K, and a Half Marathon, along with a unique 10K Ruck option.

The race unfolds in beautiful Queeny Park, guiding participants through shady, rolling, and fast gravel trails. The 5K consists of one lap, the 10K two laps, and the Half Marathon challenges runners with four laps of the well-marked course, ensuring professional chip timing for all. Aid stations are conveniently located approximately every 3.25 miles, stocked with sport drinks to keep you fueled. Typical race day conditions in mid-May present comfortable highs around 77F and lows near 57F, with a 17% chance of precipitation, creating an ideal climate for a spring run.

Beyond the enjoyable course, participants are treated to a host of excellent perks, including a big, custom finisher's medal, a Rockinator Racing Backpack, and a soft-spun event T-shirt. Free action photos and finish line video downloads capture your accomplishments, and podium awards are presented to the top three in all age groups. The race proudly supports the Rockwoods School District Cross Country program, with 100% of proceeds helping to provide shoes, jackets, and general program support for kids. Join fellow runners at the Racers Village at the Smith Pavilion in Queeny Park for a memorable day that perfectly kicks off the season.
