The guy who wrote the original description was smoking crack. Starting at the gravel pit (middle trailhead) is a lousy idea. As one other reviewer noted, he walked much of the uphill. Start in Glen haven. The ride up is fun and technical. Then choose your own adventure, either do it as an out and back, or ride down to the gravel pit, or ride all the way to Drake. The last two options are seriously technical. Down to Drake is double black diamond. He claims "unridable hike a bike sections", which is true if you don't bike double black. I ride 99.5% of it, but I am balls to the wall the entire way down. I would compare it to the rock garden section of Hall ranch, but for many many more miles, and looser and more eroded.*
Floods in fall 2013 washed out a lot of the downhill. Very eroded and significant hike a bike downhill even for the downhiller. The erosion caused wheel sized pot holes to form in the middle of the trail in many places. I have been biking back down to Glenn Haven rather than down to Drake.
