I'm a retired Army veteran of 25 years of service. I originally joined the Army to be a mechanic but ended up switching up career fields a couple of years after enjoying some time turning wrenches. I spent the last two decades learning anything I could about a pretty volatile region of the world and the last 15 years of that were spent as a warrant officer eager to learn all aspects of Middle Eastern culture (I love the regional food).
From a running perspective, I started running at age 8, but took a break for a couple of years until I joined the military. I love running, and while I was by no means the fastest one around, I usually averaged around a 14 minute two-mile run. I was very fortunate in the military, meaning that I used to buy the cheapest shoes around, occasional jump out of an aircraft, and yet I don't have feet, knee, or leg issues that a lot of former military people have developed. Also, I didn't get into 5k or 10k races until much later in life, but I have grown quite fond of the crowds that form to do such events.
