Traverse the Cedar Mtn Wilderness Area on the N-S axis, including the spine of the ridgeline.  You must:  Summit the three named peaks (Tabby's Peak, Cedar Benchmark (HP), and Hastings Benchmark); Stay high (no dropping to roads that run parallel to the range in-between the named peaks to save time); Traverse the entire wilderness area (either direction).

Jordan Kremer submitted the route:

Start at the closed gate on Sulphur mountain road just past Casitas Springs. 10.23 miles to another identical gate and then back. total round trip is 20.46 with 2572 ft of elevation gain. (Or you can do it the other direction.) The road between the gates consists of fire road, double track, and a little bit of asphalt at the far end. Good scenery and very runnable the whole way. A very common place for people to run in the Ventura, Ojai area.
