The Palmer Lake Trail Half Marathon and 10K means wide opens spaces and downhill finishes!! Join us June 2nd in Monument CO for this 4th Annual trail race along the Santa Fe Trail and Greenland Open Space.  

The new staging area in Monument allows for MORE PARKING and has an easier access off the 25 freeway, making it easier for runners to get to the event venue on race morning. The Half Marathon course will see beautiful landscapes along the Santa Fe trail as they race to Palmer Lake and to the amazing Greenland Open Space with picturesque front range mountain views. The 10K runners will be treated to the same Santa Fe trail landscape as they turn around at Palmer Lake Rec Area. 

Oh... don't forget the 3 miles of downhill towards the finish line!


*We have adjusted our prices, so that they do NOT include a race shirt. If you would like to take advantage of the shirt option, it is $5, and can be added in the Swag area of your registration.  For those runners adding the shirt option, we ask that you register at least 10 days prior to race day, to be guaranteed of your shirt order. If you are within the 10 day window, we will ask you to pick up your shirt after the race, from the sizes available. We will do our best to accommodate all requests.

SHIRT PURCAHSE OPTIONS ARE NO LONGER AVAILABLE ONLINE.
