The course begins at 10,780' ft, starting at the base of Arapahoe Basin, Mountain Goat Plaza, head up to the High Noon parking lot, then to last chance.  You will cross highway 6, get on the A-Basin summer road.  You will follow the summer road up to Black Mountain Lodge.  From Black Mountain Lodge you can see the views of the East Wall - some of the coolest terrain at Arapahoe Basin. We've added a new part of uphill this year out to Zuma Cornice area. You will then continue on it to the saddle, crossing over to the top of Montezuma Lift, head out the Lenawee trail.  From this view point you can see all the way back into the old town of Montezuma and all the high peaks that surround Arapahoe Basin, taking world class views, as you summit Little Lenawee peak.  At the summit you will turn around, head back down.  You will head across and hit the Summer road, stride back down. This portion of the downhill will include Half Moon Vista singletrack.  Once you see Black Mountain lodge again you will take a right onto another world-class singletrack, which is the Argentine North Fork trail, taking cover in the beautiful shaded forest, the Argentine singletrack twists & turns, an adventure in itself, taking you all the way to the bottom for a finish in Mountain Goat Plaza, where there will be live music and food for all.  

**The race course is located on approved established trails in the White River National Forest.

SAFETY LANGUAGE

The course is the most direct route to the high alpine, it is steep, but intuitive, you will be pushing hard for the summit, putting yourself to your capacity, lungs, grit, and strength. Please note, we will have the course well marked, it is imperative, for your safety, you follow precise path of flagging.  On Little Lenawee summit area in particular, please be prepared to slow down, pay close attention to your footwork in the technical areas, if you kick a rock loose, immediately yell 'rock' to notify fellow competitors you have kicked a rock loose. If you are further down the course and you hear, 'rock!', please do not look up, please turn your back and protect your head.  We can't stress this section enough, careful footwork, look out for the safety of yourself and fellow competitors equally.

We will provide hydration for all participants at two aid station on course & finish line.
