@JShare87 - While I would love you to join me in Boston in 2018, I want to echo what others have said. The marathon is a completely different beast than what you have been running. The physical demands are awesome and if not handled carefully, could result in injury. The training will change your life.....you will need to carve out tons of time, plan on sleeping more than you have ever done before, and you will likely become more in tune with your body than ever before. The ability to manage increased training while not burning out your legs/hips/ankles/IT band/etc on 50, 60, 70 miles per week is difficult. If you pursue a 3:05 marathon, you will be stressing your body in ways that you can not imagine. The accumulation of aches and pains over the training cycle will be your greatest challenge....and unfortunately, you don't know you have gone too far until, many times, its too late.
I almost didn't make it to the starting line of my first marathon because I was training too fast....too hard. My training for my half marathon, my body could handle. Doing that same pace as my half marathon training, I incrementally moved up to full marathon training didn't work out well as my IT band eventually said "no mas!".
Running a marathon is an amazing accomplishment and I don't want to say "Don't try to BQ", but please go in with eyes wide open and be prepared to back off on pace, if you think you may be getting close to the brink.
Good luck and we are all here to help and cheer you on!
