Training for a 5 km running race

I used to run a lot and then when I became pregnant with my first son, my running was sporadic (even though I had bought a running stroller). Now that I feel I am fully recovered from my post-pregnancy injury, I am training for the October 19 Toronto Marathon. I won't be doing the marathon but the 5km race. I'm looking forward to it and I am using Runner's World magazine issues to help me train. I have no time to learn from a running club. 

Unfortunately I have to do most of my training indoors. It's better than nothing. I don't have a double stroller to push my 2 sons and my husband is taking night courses. This leaves me no other option but to go to a gym and train on the treadmills and my sons are having fun in the daycare centre there.

This will be my first time training on a 100% raw diet. Even when I was dabbling in raw in the past, I still ate oatmeal for my runs, thinking that fruits and vegetables would not be sufficient for me. Now, I know differently and it hasn't been as hard as I thought it would be; I've been eating well. I just haven't been getting enough sleep in order to recover. 

I'm running raw!! Woo-hoo.
