Bridge & Dam Half Marathon

Saturday, March 23, 2024 • Lake Ozark, MO • Course Map

Set for its 9th annual running along a reservoir known as the “Magic Dragon” and the “Missouri Dragon” for the serpent-like shape it cuts through the land here in central Missouri, the Bridge & Dam Half Marathon & 10K takes runners back and forth across a pair of bridges over the Lake of the Ozarks, a massive reservoir created by the damming of the Osage River back in the 1930s.

Runners are set to start the race on the bridge at Bagnell Dam, which created the lake when it was completed in 1931, and now backs up the second-largest man-made lake anywhere in Missouri. After leaving the starting line, runners will head south along Bagnell Dam Boulevard for the first mile and a half or so, and then turn left at Horseshoe Bend Parkway.

They’ll only spend a brief stretch on Horseshoe Bend, however, before turning back onto the route that will take them across a second bridge over the lake, which spans some 55,000 acres and features more than 1,000 miles of shoreline, including well-known lakefront areas like Osage Beach and Sunshine Beach.

Runners will turn right onto Las Campanas and then weave their way along the riverfront before heading back to the finish line on the other side of Bagnell Dam.

Walkers are welcome in either the half marathon or the 10K, as long as they can finish their race within the course time limit of 3.5 hours, organizers say — which works out to a pace of 14 minutes per mile or faster for the half marathon.

And is the course hilly? Here’s how the organizers put it on their website: “Lake of the Ozarks is hilly, so yes you will have some hills! It is a beautiful, scenic and challenging course. Train for hills once a week and the feeling at the finish line will be that much sweeter!”
