I set a goal on Nike to run 5x week for the next 6 weeks (Nike "recommends" 6x a week -- what??) which is really ambitious but also, not crazy! And really it just counts down from 30 so one week if I'm feel ambitious I can run 6 or 7 days. Also, there is no length requirement so if all else fails I will resort to the good ol' #mileaday.
Another goal is just for that little "shield" to light up at the end of the year to tell me I was active every month of the year!
What helps you stay motivated?
