Laissez les bons temps rouler at the Carnival Frolic 13.1 & 5K, celebrating its 10th anniversary on Saturday, February 14, 2026, in Decatur, Alabama. This vibrant event, kicking off from Founders Park, invites runners to embrace a festive, carnival-like atmosphere, offering a USATF-certified half marathon, a half marathon relay for teams, and an individual 5K race. The scenic course winds through Decatur's acclaimed historic districts, along the picturesque Tennessee River, and through the beautiful Point Mallard Park. Runners can expect a mostly flat elevation profile, with one past participant noting only a very minor incline leading to the finish. Typical race day conditions for mid-February include highs around 55F and lows around 34F, with a 17% chance of precipitation.

What truly sets the Carnival Frolic apart is its commitment to fun and celebration. All participants receive a festive race shirt, carnival swag, and a collectible finisher's medal (or team medals for relay participants). Beyond the course, the race culminates in an unforgettable post-race celebration at the Carnegie Visual Arts Center, where finishers can indulge in delicious Mardi Gras donuts, beignets, red beans and rice, and enjoy a complimentary mimosa or cold beer. With a generous 3-hour and 30-minute cut-off for the half marathon, it's an accessible race that combines competitive running with a lively community spirit, attracting both seasoned athletes and casual participants. Cash prizes await overall half marathon winners, and age group awards add to the excitement.
