JogTunes and Dr. Bob selected all the family friendly running pace tracks and 2 walking pace tracks from the June 2016 Billboard Top 100 list. They're sequenced for warming up (105 to 150), running (148-180) and cooling down (150-124). This is one great 51 minute, mixed genre workout! Please be sure you're medically and physically fit for the Sia track at 180. You can always shorten your stride length or slow your pace. Enjoy, and run safe!
