​Ugly Sweater Family Fun Run
Saturday, December 11   I   10 a.m. start   I   Carpenter Park Fields


Celebrate the spirit of the season by participating in this unique event with family and friends! Join us for Thornton's first-ever Family Fun Run to be held at Carpenter Park Fields on Saturday, December 11. This untimed Fun Run is open to runners and walkers of all ages and abilities. Choose from our 5K course that winds through the park or an easier fun run course around Carpenter Park Fields (8/10ths of a mile). What a great noncompetitive way to start a winter day! We hope you will plan to stay and enjoy WinterFest after the fun run where you can enjoy warm fire pits, food, entertainment, craft vendors, ice carving, kids crafts, a heated beer garden and a visit with Santa Claus himself!

The first 150 participants to register will receive a commemorative mug. All participants can enjoy post-race refreshments in Santa's Village following the event.

The cost to participate is $5 per individual or $10 for a family of four.
