Upping the Training

Just now I decided to set a proper 'professional' schedule for myself so I downloaded a training log from the Polar website. I have to run 4 times a week! And just this Sunday I'm going to have to run 8k! How on earth I'm going to reach that target distance when I've only run a maximum of 5.5k my entire (albeit short, thus far) life is beyond me. Well, it looks like training just went up a notch!
