Embark on a truly unique Valentine's weekend challenge at the Iron Heart race, set for February 14, 2026, in the scenic Maramec Spring Park of St. James, Missouri. This event caters to a spectrum of trail enthusiasts, offering distances from a 5K, 5M, 10K, 15K, 10M, 20K, 15M, 20M, 50K, 50M, 100K, all the way up to a formidable 100-mile ultra. The Iron Heart is renowned for its welcoming atmosphere, providing a perfect opportunity to push your limits, whether you're chasing your first trail finish or an ultra buckle.

The course, known for its multiple-loop design, guides runners through the picturesque heart of the Ozarks on technical singletrack dirt trails. Expect a moderately challenging run with roots, rocks, and ruts across two beautiful and historic paths: the 1.8-mile Leatherbritches Trail, winding through pine and oak/hickory forests with views of the historic Maramec Iron Works mine pit, and the 3.2-mile BallHooter Trail, featuring approximately 246 feet of elevation gain per loop. Runners can anticipate typical race day conditions with highs around 44°F and lows near 24°F, with only an 11% chance of precipitation, making for brisk and invigorating winter running. A well-stocked central aid station, located at the BallHooter/Leatherbritches changeover, ensures runners are supported with water, electrolyte drinks, and even famous hot quesadillas, a highlight for many participants.

The event kicks off from the Massey Hill Shelter at Maramec Spring Park, which serves as the hub for packet pickup and a pre-race pasta dinner. Runners consistently praise the Iron Heart for its blend of challenge, natural beauty, and strong sense of camaraderie. Its multi-loop format means you're never truly alone, frequently returning to the main aid station and the supportive energy of fellow runners and volunteers. Celebrate Valentine's Day by embracing the "Run Love * Run * Repeat" ethos amidst stunning Missouri trails.
