Here is a Map My Run link to the 50k loop # 1.
For the next two loops you will go directly from the beach house down the road to the horse trailer parking area and continue on the same course( skipping the east meadow and campground) At the end of the third loop you will take a left up a short hill to the finish at picnic shelter # 5.
