What is Race the River?

The San Antonio River Authority in partnership with the San Antonio River Foundation are excited to launch the Race the River Paddling Series. Amateur and experienced paddling racers from all over are invited to participate in all 4 races across the San Antonio River Basin.

An awards ceremony with prizes for the top three finishers in each category in each race will be held following each race. These races will draw together paddling racers across the region and state to visit and become part of our river community.
