Runner girth hitched to a harness.

Common runners are the single and double. Single runners are tied in loops from 6 to 7 feet of 9/16-
inch tubular webbing. You can tie runners from 1-inch tubular webbing, but the wider webbing is
bulkier and more difficult to work with. Use the Ring Bend to tie your runners. Tie each loop, then
hook it to a stout tree limb, clip a stirrup or aider to the loop, and bounce your body weight on it to
draw the knot up tight. A wet knot gives the tightest set. As a final precaution, you can tape the tails to
the loop. Stitching also works but is difficult to undo when you find yourself in a tight spot and in need
of a single length of webbing. Inspect your Ring Bends before each use, and retie if they have gone
soft or the tails have shortened.
