Getting back in shape

surf_frog34

I've kinda let myself go over the last year, and am ready to get back into shape. My eating habits have gone to fast food, and that is the first thing I hope to change. I'm gearing up for a half marathon this fall, a full marathon in the spring, and the ultimate goal is the Kona Ironman Triathlon before I'm 40 (4 years away). Any and all help is welcome, and if I can help any of y'all, let me know.
Thanks, Brian
