Does anyone have an interval watch that vibrates, or at a minimum is loud enough to be heard over road noise (cars, etc) and music? I'm amazed that with today's technology I can't find a vibrating watch to alert me when the intervals are up....
I have a 5+ yr old Timex Ironman watch that I've always been able to hear over road noise. I don't use any type of music on my runs, so I can't speak to that part of your question.
