For a while now I have been running once a week at a distance of 5 miles, this is a mileage I feel quite comfortable with. I then decided I need ed to more more regularly in an effort to improve my speed.
I have for the last couple of weeks been going out twice a week running 5 miles each time, hence double the distance, does the 10% rule apply to an individual run, therefore saying I should not increase the run by 5.5 miles (for example), or does in apply to the overall distance each week.
Just wondering as I currently have managed to 'pull' both my calf's and I can only think its the increase in mileage.?
