About the Cajun Country Run Half Marathon

The Cajun Country Run is a USATF-certified half marathon held in late fall at Acadiana Park in Lafayette, Louisiana. The half marathon is a single loop on roads around the park, with three climbs under 20 feet according to the race. It is billed as Acadiana's oldest half marathon and shares the morning with 10K and 5K road and trail races and a 1-mile fun run. Finishers receive handmade alligator-head trophies, and proceeds support trail work at Acadiana Park.
