This is an 8.3 mile mountain biking loop ride in the McCoy Flat trail system west of Vernal. The trail climbs 650 feet from the Flat via the Jackalope Trail. From the slopes of Asphalt Ridge, Serpendipity descends in a fun ribbon of singletrack dirt. The last two miles of the loop are undulating singletrack on the Retail Sale trail.

The ride starts just south of the corral on the And Cookies trail. Just after you start riding, keep left as you pass the Jackalope return trail. At mile 2, leave And Cookies to fork right on Jackalope. Now you'll start your climb.

From this point on, the trail is one-way. Jackalope climbs a dry slope among junipers, then reaches a scrub and grass ridgeline. About 1/2 mile before the top of the ridge, Serpendipity forks right. 

Serpendipity immediately begins to plunge down a ravine, dipping through the bottom, then flying high up into the brush. It's a continuous swoosh. Poetry for your bicycle.

Gene Poncelet climbs Jackalope. The terrain here is clay with bits of rock. Occasional wildflowers sprout among the junipers.

After 1/2 mile, the slope lessens, and the trail zooms across the flats, heading generally downhill. The trail straightens, and the base is smoother.

Jake Weber rocks the serpent.

As the trail hits the flat, it becomes hardpack dirt. Grasses fill the space between the brush.

At mile 6.3, Serpendipity crosses the McCoy Flat paved road. 1/4 mile later, it joins Retail Sale. Keep right at this fork.

Jake gets up some speed heading toward the Flat.

Retail Sale dips and twists north 2 miles north to the trailhead to complete an awesome loop ride.
