Get ready to run on September 19, 2026, starting at 9:00 am at Missouri Headwaters State Park (near Trident, MT, just off I-90 Exit 278) when a historic black powder rifle signals the start! You'll tackle about 7 miles of mixed terrain—starting with a mile and a half on country roads before diving into roughly 5.5 miles of challenging cross-country trails that echo the rugged landscape explored by Lewis and Clark, complete with two railroad crossings. Carpooling is highly encouraged since parking is tight, so grab some friends and get ready for an adventure!
