Lake Michigan RTS 10K

The Lake Michigan RTS 10K, taking place on July 11, 2026, offers an exceptionally challenging and rewarding experience, though it is definitively located along the Lake Michigan shoreline in Michigan, not Chaska, MN. This unique event, whose name stands for Road, Trail, and Sand, lives up to its moniker by delivering a diverse course that pushes runners across varied terrain. Participants will navigate a route that begins on asphalt before transitioning into demanding, hilly trails and culminating with a steep incline through soft dune sand. The course, much of which winds through private property, provides breathtaking views of the Michigan wilderness and surrounding lakes, sights often inaccessible outside of this race.

Known affectionately as "the toughest race you'll ever love," the Lake Michigan RTS 10K has a reputation for its difficulty and the strong camaraderie it fosters among runners. Typical race day conditions in July can see highs around 83F and lows near 63F, with a 14% chance of precipitation. Due to the potentially hot conditions and the challenging "dune bowl" section, all participants are required to carry their own hydration system, with water available at the start to refill bottles and at the finish line. The race kicks off at 8:30 AM, with parking opening at 7:30 AM at the start/finish location.

Beyond the challenging course and stunning scenery, the Lake Michigan RTS 10K is distinguished by its commitment to a noble cause, with all proceeds benefiting P.O.R.T. (Pediatric Oncology Resource Team) through the Corewell Health Helen DeVos Children's Hospital Foundation. Finishers are celebrated with a premium Lake Michigan RTS sweatshirt, a designer medal, and a well-deserved treat of frozen yogurt and fresh watermelon. Runners also look forward to a refreshing spray from a fire hydrant near the finish line, adding a playful touch to this otherwise formidable race.
