About 10 1/2 feet. it was 3 bow lengths.

A doe came from down wind as I had curiosity scent on my silencers. I was leaning against a tree wtching a trail uphill. I heard a noise and peered around the tree, as the doe peered around also. I was holding my recurve knocked and ready, and by the time It was up and drawn the doe was gone. 3 Leaps and it vanished, that was the quickest I had seen anything ever move.
