This Saturday I'm heading up to finalize a few sections of trail along the U-Bar trail on the Cabin Loop section of the course and plan on running what will be about 50K starting at the Washington Park Trailhead.  I'll be leaving Phoenix at 4am Saturday and starting at 6am from Washington Park.  The route will be a climb up the Rim on the Arizona Trail, 4.5 miles east along the Rim Road and entering the Cabin Loop at Houston Brothers.  We'll divert across the Barbershop Trail (not a part of the course but a great trail) to the start of the U-Bar Trail.  We'll head north from there up and down the canyons and then reaching Pinchot Cabin we'll take Fred Haught Trail all the way back down to Washington Park.  Low point of this section is 5,800 feet and gets a little over 7,900.  Has right at 5,000 feet of climbing.  I have a PDF of the course map below you can download for a topo of the course.  Email me at azadventures@getoutgetlost.com if you are interested and want to carpool or just want to make sure we wait for you at the trailhead!  

Here's a video of the course from miles 24-46 on the climb up the Rim and around the first series of trails in the Cabin Loop.  Still fresh off winter snows so the area hasn't had a chance to grow the meadows and flowers yet but still very pretty and great running.
