The River Run 5K and Kids Fun Run
About this race
Experience the shoreline at its very best!
This scenic 3.2-mile flat course winds through the historic charm of Old Saybrook, Connecticut, offering runners and walkers breathtaking views along the Connecticut River and the picturesque marshes of North Cove Road. Feel the coastal breeze as you travel past one of the shoreline’s most beautiful waterfront stretches before crossing the finish line where it all began — at the historic site of the original Fort Saybrook.
Whether you're racing for a personal best, walking with friends, or cheering on your little ones in the Kids Fun Run, this event is about more than miles — it’s about community.
The 5K Run/Walk and Kids Fun Run proudly supports Saint John School in Old Saybrook, CT. Proceeds help further Saint John’s mission to inspire individual growth, self-discipline, confidence, and Christian service — forming students who grow into respectful, compassionate citizens.
Join us for a joyful morning of fresh air, fellowship, and shoreline beauty — and be part of something that strengthens both body and community.
