Shuttle busses will be running from the Transfer Station to the Trailhead. DO NOT PARK ALONG THE ROADWAY OF NM HWY 6. Bag check will be available at the race tent.

The courses

The 5K goes along our “Bowl Trail” on a mixture of crusher fine, hard pack dirt, and sandy trails. There are a few rolling hills. Runners will pass 2 water stations on this course right before mile 1 and mile 2.

The 10K shares the first .6 miles with the 5K, before heading west and ascending a steep hill to the “Overlook Trail”. Once on the Overlook Trail, runners will go up a steady incline until about mile 2.25 before hitting the high point of the course and descending back to meet the 5K trail to finish the race. This course is a mixture of crusher fine, hard pack, and sand with over 700ft of elevation gain. Once at the top, you will have great views of the valley and surrounding mountain ranges. You will hit water stations before mile 1, at mile 1.5, mile 2, mile 3, just before mile 4, and mile 5.

The Half Marathon is an extreme challenge. It shares the first 2 miles with the 10K course before ascending up the west face of El Cerro de Los Lunas. Runners will head up a few switchbacks before getting to the summit around mile 3. After summiting, runners will head down the east face of the hill, down the bluff road and hitting a flat and sandy stretch at the bottom. After the sandy stretch, runners will be on Huning Ranch west loop rd for a bit, heading out the gate and taking a couple of quick left turns before hitting the turnaround. After the turnaround you will do it all over again with the ascent of the east face which is the most challenging portion of the course. After making your second summit around mile 8, you are treated with downhill for most of the rest of the race as you descend down the switchbacks before reconnecting with the 10K trail. This course features 2100 feet of elevation gain on crusher fine, hard pack, sand, and a bit of paved roadway. You will hit water stations at before mile 1, mile 1.5, mile 2, mile 4, mile 4.5, at the turnaround, mile 6.5, mile 9, mile 10, before mile 11, and before mile 12. There will also be a portable restroom near the turnaround.

We will have tons of support on the course and you will never go more than .5 miles without seeing race staff.
