Get Ready to Run, Celebrate, and Give Back!

It's time to dust off your favorite beads, lace up your running shoes, and get ready for a St. Patrick's Day tradition like no other! Since 2008, runners from across the St. Louis area have gathered for the annual Shamrock Run in Cottleville, and this year, we're coming back bigger and better than ever. Whether you're a seasoned runner or just looking for a fun family event, this 5K promises an unforgettable experience.

Race your way through an enchanting course that takes you through a beautiful park, over a whimsical stream, and past serene, slumbering lakes—it's a scenic adventure from start to finish! And of course, there’s the coveted green fire helmets waiting for top finishers. So, what are you waiting for? Get your green on, lace up those shoes, and join us for a race that’s about more than just running—it’s about having fun, celebrating community, and making a difference.

After you cross the finish line, stick around for post-race festivities, including donuts and cold beers to celebrate your achievement! It’s the perfect way to cap off a fun-filled morning with friends and family.

But the best part? Every step you take helps support the Cottleville Firefighters Outreach, a vital organization dedicated to supporting our community. Proceeds from the event help fund crucial programs like providing winter coats for children in need, offering shelter to families after a fire, and delivering thoughtful gift baskets to cancer patients. Your participation makes a real difference in the lives of those who need it most.

So grab your running gear, wear your favorite shade of green, and make this Shamrock Run your most memorable yet. We can't wait to see you there!

Participants get a race day themed shirt with registration. Shirt quantities are limited after February 26th, so register by 2/26 to guarantee you get a shirt in your desired size.
