First loop:  Start at the Morris Reservoir access to the Bonneville shoreline trail (just east of the church on 18th Avenue).  Turn left (west) onto the Bonneville shoreline trail (BST) in the meadow.  Follow the BST down to, across, and then upstream on the NW side of City Creek.  About 1 mile after crossing City Creek, turn sharply left (uphill) to stay on the BST.  Follow the BST as it ascends to the ridge crest and then contours around to an intersection with the relay-tower service road.  Turn right onto the road (uphill).  At the first road junction, stay left (downhill; note BST sign).  Follow the graded road downhill, uphill, and downhill again to where it flattens out on the Bonneville shoreline bench above North Salt Lake.  Almost immediately after the road levels out, bear right to ascend a steep jeep road;  the junction itself is faint, but the jeep road is an obvious scar on the hillside in front of you.  Where the jeep road reaches an intersection in a notch in the main ridge, turn left and ascend to the summit of Meridian Peak.  Follow the road steeply down the east side of Meridian Peak, and then up the ridge to the east.  Stay left at the first fork, and then bear left (downhill) at the junction with the road from the relay towers.  After about 1/4 mile, turn right from the ridgecrest road onto the oil pipeline service road.  Follow the service road and singletrack trail down a LONG, STEEP, locally overgrown descent into City Creek canyon.  Turn right (downstream) on the City Creek hiking trail and follow it back to its junction with the BST.  Retrace the first part of the route back to the gate at Morris Reservoir where the first aid station will be on race day.

Second loop:  Follow an unmaintained singletrack trail eastward from the gate to a steep gully and up the gully; intersect the BST 0.3 mile from the trailhead, by a water tank.  Follow the BST about ¼ mile uphill, downhill, and uphill to a fork.  Take the righthand (downhill) fork which is the designated BST.  Stay on the BST for several miles, around the south side of Twin Peaks, down Dry Creek, and back up to the Bonneville shoreline bench behind the Huntsman Cancer Institute.  Leave the shoreline bench trail behind the Hunstman Institute via a descending singletrack trail that, after ~100 yards, joins a graded road (covered water tank on the right).  Continue downhill on the graded road to a cluster of trees by the parking lot.  There will be an aid station at these trees on race day.  Just before the last of the trees on the left, turn left onto an unmaintained trail that climbs ~200 yards to intersect a more prominent singletrack trail.  Turn left (uphill) on this rocky trail up the gully to intersect the shoreline bench trail in the bottom of the gully.  Turn right.  After climbing out of the gully, the trail begins to descend gently toward Red Butte Creek.  Bear left (uphill) at two successive forks to follow a short section of singletrack that contours to intersect a graded road.  Turn left (uphill) onto the graded road and climb to its end at a covered water tank.  Ascend on singletrack to the left of the water tank and then follow this trail as it rolls down and up for about 1/2 mile to where it T's against another trail in the bottom of a drainage.  Turn right (downhill) and descend to the Red Butte road.

Cross the Red Butte road just below the locked gate and cross the bridges over Red Butte Creek.  Follow this trail uphill, around, above, and then switchbacking back down toward Red Butte Gardens.  Where the singletrack intersects a hairpin turn in a washed out, formerly graded road, turn left (uphill) to follow the road to an abandoned sandstone quarry.  Continue across the quarry and out the other (west) side on uphill singletrack.  At the first trail junction, stay left to continue ascending gently to a rocky saddle marked by a few mountain mahogany trees.  Leave the saddle leftward to descend a steep rocky slope via several switchbacks to an intersection with a better trail.  Turn left and descend into a deep drainage (George's Hollow).  Turn right (downhill) along the drainage for a couple of hundred yards, then bear left out of the drainage where the trail emerges from the scrub trees.  Cross a low ridge to the next major drainage, bear right down this drainage, and turn right again at the next trail intersection where the drainage emerges from the ravine.  Follow this trail to flat area in George's Hollow, and bear left at the next junction to descend to the graded pipeline road which is the designated BST.

Turn right (north) and follow the graded road (BST) back past Red Butte Gardens to the Red Butte road.  Turn right (uphill) for about 50 yards on the paved road, back left at the BST sign, and follow the graded road northward to the trees and the aid station where you were 3.7 miles ago.

Retrace the previous route back to Dry Creek and 1 mile up Dry Creek to the lefthand hairpin where the BST leaves the drainage.  LEAVE THE BST and ASCEND THE *LEFTHAND* (more overgrown) fork of Dry Creek (Do not follow the more obvious right-fork trail which leads to a dead end).  Follow the creek bed—no obvious trail here!—up to a little waterfall, and for about 1/4 mile farther, following discontinuous bits of game trail. Leave the drainage toward the left on an obvious but appallingly steep trail.  Follow this trail to the main ridgecrest.  Turn left (downhill) onto the mostly doubletrack ridgeline trail. Follow the ridgeline trail westward, bypassing Twin Peaks and another unnamed hump on level singletrack cutoffs on the north (City Creek) side of the ridge. 

In the saddle where the route re-intersects the BST and the oil pipeline right-of-way, turn RIGHT (northward, toward City Creek).  Descend a couple of hundred yards, then turn left onto a trail that climbs gently, then steeply, then traverses an open slope to regain the ridgecrest.  Turn right (west) on the ridgecrest trail and follow it for a couple of hundred yards to the foot of a steep climb, and bear left to bypass the climb on a singletrack spur.  Turn left (downhill) where the singletrack intersects the broad doubletrack jeep road, and follow the road down to its intersection with the BST.  Bear right (downhill) on the BST and follow it to the water tank.  At the water tank, return down the drainage that you ascended about 15 miles ago to the trailhead parking area at Morris Reservoir. On race day, the finish is the front of Dan and Sheila Barnett's house, which is about 0.2 mile downhill (to the right) on 18^th Avenue, on the south side of the street (look for the flag pole).
