What to Pack
Many of you are coming from low altitude locations, so it may be better to overpack for a weekend at high altitude. At this writing, we can't anticipate the specific weather, but it looks to be cold early in the morning, warming to perfect running weather.  

We recommend that you pack enough clothes to have layers available for any type of weather. When in doubt, please choose safety over performance. 

If it is cold: If race day is chilly (or worse), you should probably wear layers. Many runners like a synthetic undergarment that wicks away moisture. Be sure to have headwear of some sort, either a beanie-type hat that covers your ears, a headband that covers your ears, or at least a brimmed cap to keep your skull warm and keep sunshine at bay.

You may want to consider running tights and a wind jacket that guards against a cold breeze. The race shirt is a technical-blend long-sleeve, but we recommend that you bring clothes you have worn in the past.

If it is hot: If race day dawns warm and sunny, please be sure to have a hat with a brim. You may wish to wear sunscreen, but much of the course is shaded by the various pine, fir, spruce, and juniper trees. On a hot day, be sure to stay hydrated with water and drinks that contain salt and electrolytes.
 

If it is wet: If it is raining, sleeting, or snowing, you would be well-served wearing layers and a performance jacket that keeps moisture from leaking onto your skin and fends off the wind.

Recommended Footwear: 

As you can see in the photos way below, much of the course is on pretty rugged terrain, with rocks, roots, and hard-packed and soft dirt.

Personally, we like knobby-soled trail shoes for such terrain, but you know your feet better than we do so perhaps pack a couple of pairs and decide on race day which is best for you.
