A bowline tied around its own standing part so the outer loop can draw closed around an object. The small bowline eye remains fixed.

How to tie the Running Bowline

  1. Take the rope around the practice object.
  2. Tie a small bowline with the standing part passing through its eye.
  3. Pull the standing part to close the outer loop; unload it to reopen.

Safety note: These steps support practice and recognition. Climbing, rescue, lifting, towing, and other critical systems require qualified instruction and equipment-specific procedures.

Which knot should you choose?

Choose an ordinary Bowline when the main loop must stay a fixed size. Practice the running version on a small object at ground level.

Why it earns its place

Separates the fixed knot from the sliding loop, helping the attachment reopen after the tension is removed.

Where it fails

The outer loop tightens: never put it around a person. Plan how to retrieve it before sending the knot out of reach.
