A pacing device provides feedback to a user based on a preselected pace time for an activity. A linear array of colored lights includes two lights of a first color and one light of a second color and is operated in accordance with a predetermined lighting sequence. The predetermined lighting sequence makes: 1) a combination of the two lights of the first color visible to the user during a time less than or equal to the preselected pace time, 2) a combination of one of the two lights of the first color and the one light of the second color visible to the user during a first portion of a time greater than the preselected pace time, and 3) only the one light of the second color visible to the user during a second portion of the time greater than the preselected pace time.
