Description

The race starts at the Mesa Top parking area. Run east on the Grand Mesa Lodge Trail to Crag Crest, run a counter clockwise Crag Crest Loop #711.1A to #711, and back on the Grand Mesa Lodge Trail to Mesa Top parking area (this is also the route for the 30k race).

Runners then head south on Mesa Top Trail #714 to Flowing Park Reservoir (back to Mesa Top for the 50k race). Run a clockwise loop on the Flowing Park Trail (return on Mesa Top Trail for the 50m race). Next, the run connects to Carson Lake via a remote trail.

From Carson Lake, take Kannah Creek Trail #706 to Coal Creek Basin Trail #703, and Switchback Trail #705 to reach the top of the Grand Mesa. Next run west on Lands End Road #100 for about 3 miles to the Lands End Observatory; head west from there and take a right on Anderson Reservoir Rd #105.

Run 6m to Anderson Lake, and head north on Deep Creek Cutoff Trail #709 and stay right on #709.1A. Run the trail around Mesa Lake and take a right turn at the end of the lake trail. Head up on a faint unmarked trail toward Hwy 65 where it will connect you to Aspen Cove Rd. Go uphill for 1.5 miles and take the snowmobile trail on the right. Run up a steep rocky pitch (Kill Phil Hill) to the metal hwy department building at the top of the hill. Go right on the old logging trail to the big open meadow. Run south towards Reservoir #6 and run around the edge of the lake and below the dam. Run the dirt trail out to Anderson Reservoir Rd #105, and turn right heading west back to Anderson Lake.

Next, turn left onto Deep Creek Trail #709 south to Reber Cow Camp. Trail #709 crosses the road here and descends below the rim of the Mesa to Coal Creek Trail #702. Take #702 uphill to Carson Lake, and then take Carson Lake Trail #729 back towards Flowing Park Reservoir.

Finally take the Mesa Top Trail #714 to the finish.
