Bad Santa 5K
Sunday, December 20th, 2026
Do you live and run with an attitude that risking a lump of coal in your stocking is the cost of adventure? Rather throw back a finish line brew from right here in The Lou while supporting your local community? Don't want to break the holiday gift fund on race registration?
Come naughty, come nice to the Bad Santa 5K on December 20th! This timed run through Carondelet Park celebrates the Holiday Season the right way – with a party, free beer, custom race tee and much more.
The course will feature stunning winter scenes with plenty of lakes, woods and railroad tracks to explore – perfect for seasoned and casual runners alike. After the race, warm-up by joining us at Urban Chestnut's Bierhall for the Bad Santa afterparty.
We’re also collecting new and gently used winter coats, hats and gloves to benefit the Kurt Warner First Things First Foundation and Warners’ Warm-Up Coat Drive in keeping our neighbors warm during the cold winter months. Bring yours on race day, and Operation Food Search will ensure the coats get to those who need them!
In addition to the run and post-race fun, participants can enjoy a logo’d race shirt and finisher item to stay festive through the winter months.
So what the bells are you waiting for? Register now, you filthy animals!
