***COURSE CHANGE ANNOUNCEMENT*** Due to construction and road closure on Emery Street, we cannot run our normal route this year. We have made adjustments to the course and I think this is going to be a new favorite route. We will have a bit more time along the river and well get to run through beautiful downtown Merrimac. This new course will add a little distance meaning our 5k is closer to 3.4 miles so with a new course and distance there will be no new course record this year. Check the picture above or jamacoriverrun.com for more course details. See you in June!!

We are excited to announce that we are partnering with Sweet Paws Rescue for this year's race!



Sweet Paws Rescue (SPR) is a local non-profit animal rescue based in Groveland. They are a grassroots, boots-on-the-ground, shelterless, foster-based organization, primarily working within two of the poorest counties in Mississippi and Alabama. Since 2011, they have rescued close to 22,000 puppies, dogs, kittens, and cats that would not have a chance at life otherwise and also serve as a New England resource for the abandoned and displaced, as well as animals seized in cruelty cases within our home state. As a volunteer-powered organization, Sweet Paws rescue and home as many animals as other larger local brick-and-mortar organizations that have paid staff and endowments. In addition to providing the love, food, and basic veterinary care the animals need to thrive, they are providing Heartworm treatment to many adult dogs, and sometimes even life-sustaining surgeries and emergency care. The adoption fees paid to SPR only offset the costs associated with each life they save.



It is our hope that this partnership will make 2025 our best year yet and we once again look forward to giving back to our local community!
