REASON # 3 - YOU CAN DO IT ANYTIME!
Want to run early morning? Go right ahead!
What about at night time? Still doable!
What about late at night when the kids are put to bed already? That's fine as well!
What about during lunch break at work? No Problem!
What about if I just cannot sleep and figured a good run might be good for me even though it is at 3am? Go for it!
Gyms have operating hours as do renting a court to play badminton, basketball or tennis. Sport Clubs have business hours too. Swimming pools closes at night.
Running can be done anytime! :)
