The inaugural Three Bridges Marathon ("3B26"), is a celebration of the three majestic bridges of Central Arkansas: the Big Dam Bridge, the Two Rivers Bridge, and the Clinton Presidential Bridge. The course crosses all three bridges via the North Little Rock Arkansas River Trail.

The idea began soon after the Big Dam Bridge opened in 2006. The Clinton Presidential Bridge and Two Rivers Bridge then opened in 2011. Pulaski County and its Big Dam Bridge Foundation, the City of Little Rock, the City of North Little Rock and its Arkansas River Trail Foundation, and the Clinton Foundation were brought together by a team of passionate runners and talented professionals so you can RUN 3B26.
