2021 River-N-Rapids Half Marathon, Quarter & 5K

Hillsborough River State Park • 15402 U.S. 301 North ThonotosassaFL  33592 Organized by Endeavor Racing, LLC

About this event

The River-N-Rapids Half Marathon, Quarter & 5k has grown into one of our most popular events--with trails to challenge you and one of the most scenic courses in the state.

Opened in 1938, Hillsborough River State Park is one of Florida's first state parks; this original Civilian Conservation Corps park is divided by the swiftly flowing Hillsborough River with a set of Class II rapids.

The 2020 River-N-Rapids Half Marathon and 10k will have participants running along the high banks of the river above the rapids, through a variety of habitats, past some huge oak trees, over the historic CCC suspension bridge and then onto the park's Rapids Trail . The River-N-Rapids 5k will take participants across the river, across the suspension bridge and then onto the park's Rapids Trail--scenic incentive to get your body moving!
