The Big Dam Bridge 100 is an annual event in central Arkansas that celebrates the "Big Dam Bridge" over the Arkansas River. The 4226-foot bridge is the longest bridge built for pedestrian and bicycle traffic in North America. It connects over 40 miles of scenic riverside trails between Little Rock and North Little Rock. It also serves as the backbone for connecting over 70,000 acres of various city, county, state & federal parks.

The BDB 100 offers several routes ranging between 15 and 105 miles, with beautiful mountain and river scenery, as well as a few challenging hills on the longer routes. The event provides participants with well-marked courses, fun aid stations with foods and liquids, great volunteer support, event t-shirt, a unique finisher medal, post-ride food and drinks along with a unique finish-line experience.
