Overview

The Grand Mesa is a large mesa in western Colorado in the United States. It is the largest flat-topped mountain in the entire world. It has an area of about 500 square miles (1,300 km2) and stretches for about 40 miles (64 km) east of Grand Junction between the Colorado River and the Gunnison River, its tributary to the south. The north side of the mesa is drained largely by Plateau Creek, a smaller tributary of the Colorado. The west side is drained largely by Kannah Creek, which is received to the west by the lower Gunnison River. The mesa rises about 6,000 feet (1,800 m) above the surrounding river valleys, including the Grand Valley to the west, reaching an elevation of about 11,000 feet (3,400 m), with a maximum elevation of 11,333 feet (3,454 m) at Crater Peak. Much of the mesa is within Grand Mesa National Forest. Over 300 lakes, including many reservoirs created and used for drinking and irrigation water, are scattered along the top of the formation. The Grand Mesa is flat in some areas, but quite rugged in others.This is a good old fashioned Colorado mountain trail race run at high elevation. This race takes place on the Grand Mesa (near Grand Junction, CO), known as the largest flat-topped mountain in the world. The terrain varies from rocky ridges, smooth single track, grassy meadows and pine/aspen forests with views galore! The average elevation is 10,000'. The highest point for each race is the summit of Crag's Crest at 11,200' where you can view many of the 300 beautiful lakes that are located on the Grand Mesa.

From the lodge you will cross hwy 65 to Crag Crest TH and CC aid station. (.5m ) You will run a 10.4m counterclockwise loop of Crag Crest Trail and end back at CC aid station. (1550′ of climbing & descent & fun!) Now you will head back on the Grand Mesa Lodge Trail to the where you started the race (3.5m / gradual uphill). The next section you will run south on the Mesa Top Trail for 7.6m to Flowing Park. Check in at the Flowing Park aid station. Section 2 = 7.6m and 965′ descent. This section is a long gradual downhill. From Flowing Park you will keep heading South and be running a lollipop course and going clockwise around the loop part. At 9 miles from Flowing Park you arrive at Indian Point Aid Station. Then continue 5.4m back to Flowing Park. Make sure you stay left at the intersection out in the meadow so you do not repeat the loop! Section 3 = 14.4m and 810 descent then 810′ ascent. (This loop is run along the Mesa’s edge and has endless views of the San Juans and Elk Mountains!) This section has a 4hr cutoff time.Back at the Flowing Park Aid Station, you will go back up the Flowing Park Road for .85 miles where you will take a left off FS 109. You will follow a single track in a westerly-northwesterly direction for approximately 1.6 miles. To your left will be an old cabin and you will be on an old road going north. You will follow the road .10 mile north. At this point the road will bear to the right and a single track trail bears to the left. Take the single track trail to the left up the hill and into the trees. You will follow the single track and old logging road through the woods for .3 mile. You will come out in a clearing where you will see a corral to the northwest. Go about ¾ of the way across the clearing, and you will come to the Carson Lake Trailhead sign. Turn left downhill, following the markers to the treeline where you will see a 4X4 trail marker. From here down to Carson Lake, there is a well-defined trail. At the lake, cross the dam to the aid station. The Forest Service has added some additional markers at the top of the trail. This section is about 5.5 miles long.You will leave the Carson Lake Aid Station and go back across the dam to the Kannah Creek Trail Head. Follow the trail to the lower trail head. The mileage for this section is about 9 miles with about 4092’ of decent. You may pick up your pacer at Carson Lake. This section has a lot of open sections and will be quite hot near the bottom. Take plenty of water. There are multiple stream crossings in this section. Also the lower part of this section and the beginning of the next section can be very muddy if there is a big thunderstorm. At approximately mile 7 of this section, the trail has been rerouted in spots. Follow the white Forest Service arrows. This section is extremely rocky and will take you longer than you think it should. This section has a 3 hour cut off time.This is the crux of the 100 miler. You will leave the Kannah Creek Aid Station following the paved road uphill for about 200 yards where you will take a right through a gate and follow the Coal Creek Basin Trail up to the Switchback Trail. This section is about 5.5 miles long and climbs a little over 4000’. At the top of the Switchback Trail, you will come out on the Lands End Road. This will be a crew access point. From here, follow Lands End Road west for 3 miles to the Lands End Aid Station. This section is about 8.5 miles and has a 4 hour cutoff time.This section follows FS RD 105 to the northeast and has very little elevation change. You will follow the road for about 6 miles until you come to Anderson Lake where there will be an aid station just after you pass between the two lakes on the left. Shortly before the aid station, you will see trail markings to your right. DO NOT TAKE THIS SECTION YET! This is section 10. This section has a 2-hour cutoff.From the Anderson Lake Aid Station, follow the Deep Creek Trail down to Mesa Lakes. The trail is very rocky down the side of the mesa, but is easy to follow. When you reach Mesa Lake, you will take a right and go around the lake to a road. Just before reaching the road, take a right and go about 30 feet along a game trail. Take a right and go up a small hill into a small clearing. At this point, you are just off of Highway 65 and will be under a power line. Take a right and follow the trail under the power line for about 1/3 of a mile. You will come out on Aspen Grove Rd. Take a right and follow the road uphill for about 1.5 mile to the aid station. This section is 4.5 miles long with 508’ of decent and a 1hour 15 min. time limit.This section takes you back up to Anderson Lake following the Aspen Grove Road. The Aspen Grove Aid Station is at the bottom of Kill Phil Hill. Follow the trail markings along a snowmobile trail that takes you back to the top of the mesa. At the top of the mesa, there is a small garage. You will turn right (west) and follow an old logging road for about a mile and you will come out at a large open meadow. There is not much of a visible trail here. There will be a red flashing light on the other side of the meadow to guide you. A short distance after the light you will come out on FS Road 105. Take a right and follow the road back to the Anderson Lake Aid Station. This section is about 6 miles long with 936’ of climbing and 407’ decent and a 2.5 hour time limit.This section takes you from Anderson Lake back to Carson Lake using the Deep Creek Trail. From Anderson Lake, you will follow FS 105 for approximately 30 feet and turn left onto Deep Creek Trail. Cross the open area to the eastern edge of the lake. Follow the single track trail around the lake, staying between the trees and the lake. After the lake you pass through a gate and follow an old road for about 1/3 mile. The road splits; bear to your left. At that point, you should see a flashing red light. At the light, you come to an old fence line. Go due south for about 50 feet to a single track trail. Follow the trail due south, keeping the trees to your right. You come out on top of a small hill overlooking a small lake. Go down the hill and bear southeast (left) across a small drainage. Go up the hill and through the trees to Reber Cow Camp. When you reach the cabins, follow the trail down to and across the road. The trail then goes east across a meadow where it drops of the top of the mesa. About a mile after you drop of the top, you come to an intersection. DO NOT GO RIGHT! Take a left and go east again about a mile to the aid station. This section is about 5 miles long with 226’ of climbing and 721’ of decent and a 2 hour time limit. Carson Lake to Flowing Park is the same as section 4 only in reverse. Flowing Park back to the Finish line is the reverse of section 2.The course will be well marked with surveying flagging and reflective markers and chalk. Some of the night time sections will also have red flashing LED lights
