This is a fun 3.2 mile Loop. Nicer to run clockwise. There is only 500 feet of climbing but there are 20% grades. This is why I gave it the black diamond rating.
Running it clockwise, take the trail to the left out of the parking lot. Continue for about a half mile and you'll see a sign-in box and a bench - turn right and head uphill. Continuing straight will take you under the highway and over to Monolith.
There are no hard obstacles but there is a little exposure on the north side. There are a couple of hip jumps but they are not mandatory and you may not even notice them. This short loop is a good loop if you are limited on time but still want a workout. On the back side, there's a bench and if you continue straight you'll complete the loop.
If you're looking for a little longer ride, turn uphill at the bench on the back side for Castle Rock trail. Castle Rock will take you to Badger trail. Just remember as you head down Badger it will end at Highway 93. We have a loop that is planned to be built by the end of 2014, but for now it's an out and back. Out to the end of Badger and back is a nice 12 miles and 1,800 feet of climbing.
If you have two trucks, park one at Beale and one at Badger parking lots. Take Beale either way to Castle rock trail and head down Badger. It is almost 10 miles with scenic views and the downhill will put a smile on your face. This is the way the locals like to do it!
