Otter Creek Trail Festival at Harmon Lake, Mandan ND
The Otter Creek Trail Festival is scheduled for June 11-12, 2027 at Harmon Lake Recreation Area near Mandan, North Dakota. The weekend includes mountain bike races and trail runs that use the Harmon Lake trail system and nearby two-track sections. The festival also features on-site camping, food, and family-oriented activities.
Mountain bike events follow a mix of lead-in sections, a short lap, and longer laps that route riders through named singletrack features such as Tight & Twisty, Chutes & Ladders, Fast & Flowy, the Epic Loop (including an Epic Short Loop), and the Blue Sky Trail. The longest mountain bike course uses an initial lead-in of about 4 miles, a short lap of roughly 12 miles, and two additional laps of about 19 miles each. Several mountain bike distances include an event t-shirt and a post-race meal and beverage.
Two trail run options use Harmon Lake’s west side and combine 2-track, the Epic Loop, Blue Sky, Chutes & Ladders, and Fast & Flowy to return to the finish. The shorter run follows the lead-in used by the mountain bike races and passes an aid station near mile 9 on the short epic loop.
