Prepare for an unforgettable trail running adventure at the In Yan Teopa 5 & 10 miler on Saturday, September 19, 2026, set in the breathtaking Frontenac State Park in Frontenac, MN. This challenging race offers both 5-mile and 10-mile distances, guiding runners through a diverse landscape of rolling prairies, winding single-track trails, and inspiring, lung-bursting climbs. As you traverse the course, you'll be treated to stunning vistas of Frontenac State Park and the majestic Mississippi River, with a good chance to witness a beautiful sunrise over Lake Pepin. The park is home to the natural limestone arch known as In Yan Teopa, a Dakota name meaning "rock with an opening," which adds to the unique character and history of this trail experience.

Hosted by the St. Croix Running Company, this event is celebrated for its engaging atmosphere and commitment to an inclusive running community. The course, largely on un-paved trails with significant hills, provides an exciting and rewarding challenge for both seasoned trail runners and those new to the sport. Aid stations along the route will keep you fueled with water, fruit, snacks, and other surprises, but remember to bring your own reusable water bottle or hydration vest as this is a cupless event to reduce environmental impact. With typical race day conditions seeing highs around 72°F and lows around 52°F, and only a 13% chance of precipitation, the weather often provides ideal running conditions for a brisk autumn morning.

The race kicks off from Frontenac State Park, where bib and swag pick-up will be conveniently located near the picnic shelter at the top of the park. The 10-miler begins at 8:00 AM, followed shortly by the 5-miler at 8:05 AM. Runners consistently praise the In Yan Teopa race as an "amazing race" and a fantastic opportunity to test endurance and soak in the natural beauty of Minnesota. Come to compete, share stories, and revel in the camaraderie of your running family amidst some of the most scenic trails in the region.
