Ran this loop 21 August 2005 beginning at in TN Valley. Runners will find the initial climb up Marincello enough to get the blood pumping so that you can enjoy the reward of the rolling, winding downhill of the Bobcat Trail. From the low point where the Bobcat and Miwok meet the real climb begins. Here the Miwok relentlessly rises with a mellow slope punctuated by a couple of steeper sections.
Finally, the Old Springs trail branches off to the left and winds across wood bridges until the loose drop back to the TN Valley.
Trail is in great shape and shared by hikers, bikers (a couple of cyclo-cross guys too) and horses. I run this trail often (2 times a week) and was shocked to see so may flowers still in bloom and to encounter a rattle snake sunning midtrail on the Miwok up hill.
A good, easy run 1 - 1.5 hrs or 2 with mellow walk breaks
