This may be an "exercised-induced migraine-like reaction." I have had similar episodes with visual scotomas during the first few miles of a long run Often triggers are early morning runs, lack of good recovery and sleep, and hot temps. I would recommend seeing your physician if headaches worsen with exercise, chest discomfort or loss of consciousness with running. Hope this is helpful.
