Wow, I feel like the old veteran in here. I'm Drew, 28, San Diego, didn't start running until the age of 25. I was hooked and now I have run 2 marathons, 2 half marathons, with the satellite Marine Corps Marathon at Al Asad, Iraq coming up and the Silver Strand half to welcome me home in November.
I started to run simply because the drill instructors told me to. I started to realize that it was the one thing, physically, I could do to keep up with the younger kids, and now I'm plowing through 40 miles per week. I have ridiculous lung capacity, not bad for a guy who was 3 years ago lodged behind a desk 55 hours a week weighing 260 lbs and wheezing up a flight of stairs- the main reason I left Corporate America (I blame it for making me fat). Back in college, I started trying to run, but alcohol got in the way.
To all the newbies, keep going. It will get easier and you will improve. Before you know it, you'll be in the best shape of your life and running ridiculous mileages in one day.
Keep on keepin on.
