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?

Pop-ups MUST be weighed down with a minimum of 40 lbs/leg. 5-gallon buckets filled with water work well for meeting this requirement. This is a city law and there will be no exceptions. If you disobey this rule, you will be asked to leave, and your time/distance will not be recorded. Not following city/park rules puts our permit in jeopardy. There is no camping allowed outside of race hours. Therefore, no camping is allowed the night before the race or the night that the race ends.

A runner's manual will follow with more details.Our permit allows for about 20 RVs in the east parking lot. When you register, you will have the option to reserve a permitted spot for an RV. Once those are taken, we cannot allow for any additional RV's. A vehicle that is slept in or used as a runner's crew area is not an RV, especially if it fits in a standard parking spot. Last year, RV permits were free. However, permits were reserved and not used or cancelled. As the race grows this could unnecessarily prevent others from getting an RV spot. To prevent this is 2025, RV permits will
be $20. All RV permit fees collected will be donated to The City of Loveland.
