Running a Marathon: Update

As it has been around 3 weeks since i last posted about my running, i feel although i should give an update on how i am progressing.

I have been sticking to my running and been jogging lightly around 2/3 times a week, stepping up as the days progress. Having started back from a months break, i have been boxing for 1 week now, which helps greatly with fitness. I am planning on stepping up the intensity of my running as the future comes. However, i have been struck with a minor back injury, towards the left side of my lower back, which could slow my progress.  I am unsure what this is and am slightly concerned on whether to ignore the pain and fight through it, or contact a doctor.

The exercise side of things i am totally fine with, but its the diet part that i struggle with. I just cannot seem to eat the right foods. Is there any tips or hints to help me improve my diet? This will help with both my running and my boxing.

Thank you very much for all the support.

Running a Marathon

Throughout the past 3/4 weeks i have been jogging with a friend around 2 to 4 times per week. This is because i hope to run a marathon or half marathon in the future for a charity that helps an illness called Lupus, a disease one of my close friend's mother suffers with. I will begin to start off with light training and become more and more intense as time progresses. I am really hoping I've got the commitment and self discipline to stick at it and hopefully finish. I was wondering is there any diet tips or exercise programmes to help me and my friend along our journeys?
