Holiday 5K, 10K, & 13.1M at Slidell, LA

Holiday 5K, 10K, & 13.1M at Slidell, LA brings the half marathon (13.1 miles), the 10K and the 5K to Slidell, Louisiana, on December 19, 2026, with all three starting at 8 a.m. The courses are built to show off the character of the town, every finisher gets a medal, and holiday costumes are encouraged, with prizes for the best of them.

Pick the distance by the training, then dress it up however you like. For the half, the useful preparation is a weekly long run built up over ten to twelve weeks until 10 or 11 miles feels routine, plus a couple of runs at the pace you want to hold. The 10K is the honest pick for a shorter build and still gives you a real number, while the 5K asks for little more than a warm-up and some nerve over the first mile.
