Description

XX Extension is an advanced trail that is typically run as an out-and-back loop that includes Bloodshed. The entrance/exit is at the dirt mounds at the western end of XX and across 107th Street from the bottom of Dynamite Road. Most people use the large mound of dirt in the middle of the area to gain enough speed to make it up the entrance/exit hill on the west side of the area.

The trail is composed of a mixture of ups and downs (like XX), long heavily armored areas, and rocky elevation changes. Inbound, near the western end, will be two trails off to the right; these are the exit and entrance to the Bloodshed loop. Stay straight and there will be a fork in the trail. Keep left and power up a rocky climb to the top. A vista at the top rewards you with nice views of the Cal-Sag Channel and the Cal-Sag paved trail on the opposite side of the water. Continuing on will bring you to a technical descent on the back side of the hill. The standard line is to the left and a more difficult, alternate line is on the right. Keep your weight back and your tires rolling.

At the bottom of the descent, heading to the left is an easy exit back east via Canal. Heading right will continue on XX and turn eastbound toward the entrance/exit. Those who choose to do the Bloodshed loop should take the first left. The second left is the Bloodshed exit. Continuing straight goes back to the entrance/exit.

Nice mix of tech and flow. Great trails for an urban area.
