The Bull Run
trail is an excellent slickrock and singletrack ride along the cliffs on
the northern edge of Bull Canyon. The actual trail is 5.4 miles in length, with a
vertical change of around 1000 feet. Bull Run is used mainly as a downhill route,
either as part of the Magnificent
7 or as a loop ride using Getaway as the
uphill. Riding season is April through mid-November.

Most riders park where the Gemini Bridges Road
turns off Highway 313, at the top of Getaway at 6000 feet altitude. The
actual Bull Run trailhead is 1.1 miles down the Gemini Bridges road. (If
you choose to descend Getaway from the top, the 7-up
trail will take you over to the Bull Run trailhead.)
At the bottom, the Bull Run trail ends on Arth's
Corner a few feet from Arth's
trailhead on the Gemini Bridges road. (For those who want to visit the
Gemini Bridges, the trail crosses the road just above the bridges. From
the bridges, you can pick up continuing trail -- Arth's or Great Escape --
about 1/10 mile downhill.)
Starting out the ride to Bull Run via Getaway at the upper
end of the Gemini Bridges Road.
The new (in 2015) upper Getaway trail (plus a piece of 7-up) provides a
singletrack link down to the Bull Run trailhead.
Bull Run can be ridden as an out-and-back from either
direction. It's not that tough as an uphill -- although Getaway is much
easier. You can start from the top as
described above, or park at Arth's Corner trailhead
and head up from the bottom.
Most riders would prefer to ride Bull Run
as a loop from the top. For the uphill, use the Gemini Bridges road
or Getaway (recommended).
mile 1.1, here's the singletrack trailhead.
Ready to rumble?
My ride description starts from the top, where the Gemini Bridges
road meets Highway 313, using the classic route. That's to keep the mileage and directions
consistent for riders who are doing a shuttled ride such as the Magnificent
We're skirting the head of a slot
canyon. We'll be heading east on a finger of rock between this canyon and
Bull Canyon to our right.
Bull Run is the first segment of an epic 26-mile point-to-point ride called the Magnificent 7 or Mag
7. This ride finishes on the Potash Road at the bottom of the Portal
Trail. A road return means 25 miles of road and paved bike
path with 1900 vertical feet of climbing -- do-able if you have enough
time, fluids, calories, and leg.
Sneaking along the edge of the cliffs,
with ledges uphill and down to make the riding fun.
Begin Bull Run by heading down the Gemini Bridges road from
Highway 313. Ride 1.1 miles. At the marked trailhead, turn right for 100
feet on doubletrack, then right again onto singletrack at the kiosk. The
trail to the left is the new 7-Up trail.
alternate route to the trailhead is to descend Getaway.
When Getaway crosses 7-up at mile 1.5, turn right on 7-up (cross the
Gemini Bridges road) and ride to the Bull Run trailhead.
View to the north. The two buttes at
mid-right in the photo are Monitor and Merrimac.
Bull Run heads south on red dirt through pinion and juniper. The trail
starts on dirt and rock of the Curtis
Formation, then drops onto the top of Entrada sandstone.
Although known as a downhill romp, Bull Run will ask you to do a bit of
climbing as you roll down the hill.
The trail is easy to follow, with logs
and rocks to corral you in, and yellow paint stripes to mark the riding
Bull Run curves around a small canyon, then follows the
canyon rim eastbound. The canyon will be to your left. This isn't Bull
Canyon yet. The ride is mostly slickrock with short stretches of red dirt.
rolls through pinion pine forest with the La Sal Mountains to the east.
You'll flirt with the cliff edge on a mildly technical
sandstone surface. The trail is well-marked with yellow paint stripes on
the rock. Route-finding is quick and simple, so even a first-timer on this
trail can motor right along.
The temperature is 37 degrees. The clouds are moving up on the La
Sals. I'm riding with three layers on
my core, and another three emergency layers in the Camelbak (racing shell
jacket plus two plastic ponchos). Plus a foil blanket. Heavy thermal
tights. Plus a headband.
Riding alone on cold days means you come prepared to spend the night.
At mile 1.6 of Bull Run, the trail comes to a narrow spot with
cliffs to your left and your right. A fence crosses this spot at N38 35.230 W109 45.502.
Step over the gate and continue. Bull Canyon will now be to your right.
Typical riding view along the edge of
Bull Canyon, with waves of undulating Entrada sandstone.
About 1/10 mile after the fence, the trail temporarily drops
away from cliff edge (and from the old unofficial "green dot"
route) to avoid a bighorn sheep area. At mile 2, you'll head into a pasture
and join doubletrack for 1/3 mile. Here the connector from Getaway joins
on your left. Keep straight. Soon you'll be back at cliffside with
Bull Canyon to your right.
Gene cruises the edge of the cliffs
with the Entrada sandstone slopes of Bull Canyon in the background.
The sandstone is now more continuous, and a bit smoother
than on the upper singletrack. Stop and enjoy a few looks into Bull Canyon
on your right.
Looking west towards Crips Hole from
After crossing the Crips Hole road, the trail becomes dirt
singletrack with occasional rock. After a mile it veers north across a
meadow and crosses the Gemini Bridges road about
1/4 mile uphill from the arches. Bull Run will end at Getaway
and Arth's Corner.
Derek hits a steep rock ramp with a
90-degree right turn at the bottom.
If you're doing the classic loop ride (see below), fork right
when you reach the
Gemini Bridges Road instead of crossing it. Turn right again 1/4 mile later
on the short road spur to the
bridges. Bike parking is on your right as the little road loop curves to
the left above the bridges.
If you're doing the more-popular loop ride with Getaway as your uphill,
continue down Bull Run when the trail crosses the road. Proceed to the
intersection where the bottom of Bull Run meets Arth's and Getaway.
Looking west as we roll the edge of Bull Canyon.
If you're riding the Mag 7, continue
downhill on Bull Run to the trail fork where Bull Run meets Arth's Corner
singletrack and turn left on Arth's. An alternative descent is to
fork right on Arth's and cross the Gemini Bridges road to descend Great Escape.
Bull Run is my favorite section of the Mag 7, and I recommend it highly
as a stand-alone ride as well.
Derek and Gene take in the view.

From I-70 and Crescent Junction, drive south on US-191 for 20 miles (about
9 miles north of the Colorado River if you're driving out from Moab) to
Highway 313. Drive 13 miles on 313 to the Gemini Bridges sign and turn L
onto dirt road. Getaway trailhead near 313 (traditional shuttle drop-off): As
soon as you pull onto the dirt road, find a spot to park. This is the
trailhead if you're doing the traditional Mag 7 or doing the
lariat loop ride using Getaway from uphill. Getaway is on the north (left) side of the
road about 200 feet from the highway. Bull Run trailhead: Head down the Gemini Bridges dirt road
1.1 miles to the Bull Run
trailhead. Gemini Bridges: If you're riding uphill to Bull Run from Gemini Bridges, drive
down the gravel road 6 miles and turn right to the Gemini Bridges parking area. Arth's
Corner trailhead (bottom of Bull Run and Getaway): Drive 1/4 mile downhill from the
bridges and spot the trailhead on the left side of Gemini Bridges road.
