I found this blog post about a young woman named Jen A. Miller, who has experienced a few hardships in her six months: her boyfriend left her for another woman, bought a house and her grandfather died. In her story, she guides us in her changed life through running.
She started running in 2007 after the six months. 5-kilometer races were the only races she ran, until she started to train for longer, more challenging races like 10 milers. Other problems does come along the way, but how she explains about how running has helped her in general could be connected to everyone. Even I could connect that running sets my mind off of negative things in my life.
