Ozark Trail 100 Mile Endurance Run

The Ozark Trail 100 Mile Endurance Run is the 18th running of an approximately 100 mile point to point trail race in the Ozarks near Steelville, Missouri. The event is based at Bass River Resort and runs through sections of Mark Twain National Forest along the Ozark Trail.

The course is nearly continuous single track with technical sections, stream crossings, and about 12,000 feet of elevation gain. The route is described as a century plus journey through remote wilderness and autumn terrain where weather and footing can vary from warm conditions to frost-tinged trails.

Race services and logistics include 13 fully stocked aid stations, crew access points, drop bag service at designated aid stations, and pacer options beginning at Brooks Creek (mile 40). A pre-race dinner and a mandatory pre-race briefing are part of the event schedule. Base camp and the finish line are located at Bass River Resort.

This running has been selected as the 2026 Missouri RRCA State Ultra Championship. Entry fees are non-refundable, non-transferable, and cannot be rolled to future years. Registration closes Sun, Oct 4 at 11:59 PM CT. Visit the organization's website for the most recent information.
