Four mile recovery run in the pre-dawn dark by the ocean path. However, a bit after mile 2, a man popped out from around the corner of the bath house and started running behind me, and every hair on the back of my neck stood up and I took off. I treated it like a race. I could hear him behind me, and I could hear him getting fainter, and I picked out something ahead - the clock at the bank that marked the end of the path - and focused on that. He was long gone after just a few minutes but I did not run mile 3 as a recovery run. Mile four was fine.
