Our 30-day Beginner’s Running Challenge will make a you fall in love with running by day 15 of this calendar.  Use this calendar to transition your dislike for running into becoming slightly (hopefully, majorly) addictive! Starting off reasonably sets the tone. By day 15 of this challenge, whether you’ll be at work, at home or at the grocery store, you’ll be anxious to lace up and hit the streets. Welcome to the inner circle!
