The First State Duathlon is a fun competition that allows fans of trail or cross country runs and mountain biking to race and ride along the trails at one of Delaware's beautiful state parks, Bellevue State Park, which is located in Wilmington, Delaware. 


Our Mission

We believe competition is healthy for the community. The goal of the First State Duathlon is to help promote and foster that competitive spirit in a fun way.
