From the base of Table Mountain and Colorado's spectacular foothills, All-Out Multicourse presents our 15th annual Kooky-Spooky from Jefferson County's NAAC Stadium… easily accessible from several nearby highways.

Of course, we'll still be celebrating the Halloween spirit so re-use your Halloween costume for our official costume contest.

This is not your run of the mill 'Turkey Trot.' This is the Turkey TREK! Are you up for the challenge? Run a steady uphill climb to the summit of the course at the 3 mile mark. Poised at the top of the hill is the infamous EGG NOG CHUG Challenge where racers (have the option) to chug 5 oz of eggnog. (Those who 'chug' are entered to win a new pair of shoes!) It's windy and wild at the top and the limitless views are UNMATCHED. Run the ridge for a mile before starting the more gradual, yet still winding, descent down the east side of the mesa. Once down the hill, racers encounter a relatively flat straight-away peppered with HAY BALES for the hay bale hop challenge. Continuing the clock-wise loop back into the park, runners find the final challenge - just one kilometer from the finish: Fill Your Pie Hole Challenge. A fresh portion of holiday pumpkin pie awaits racers there. Once the pie is 'down the hatch', the joy of the finish line isn't far away. Is this a course on which to set
a personal record? Hah! This is the course to BRAG about completing - with ALL of its holiday-themed challenges. Are you ready to conquer it?
We know that some of you require a bit more training before attempting the 10k loop. 5k and 2k distances are also offered, with a small 'taste' of the full course of challenges!
For those of you who eat hills for breakfast and wash them down with egg nog on the daily, a bigger challenge is offered at the 2025 event. New this year, the HALF TURKEY!! The HALF TURKEY visits all the challenges offered to the 10k Trek runners, and adds some mileage to get you to the 13.1 mile distance. HALF TURKEY finishers receive a MUG at the finish line to commemorate their accomplishments!
