The training period was one of the toughest times for me personally. My apartment was broken into, my dog passed away, and my work was incredibly high-stress. I didn't realize how stressful it all was until I had to both deal with my personal life as well as complete long and arduous workouts. I will say though, that running truly became my saving grace during these times. It forced me to get outside, pumped serotonin through my body, and reminded me that I'm still physically capable of accomplishing goals.
