That's a good question! I have been running, well...jogging for a number of years and when I feel really speedy, the best I can do is just under a 10 minute pace. So I hope the experienced runners give you some good tips. I have to add that I do think that cross-training with the Cathe videos, esp. those interval blasts, has helped me. Oh and listening to songs with a fast beat helps my brain quite a bit (usually happy pop-rock songs are my guilty pleasure), and I am sure to have noise related hearing loss as a result of this habit. Oh well, the price we pay for fitness, eh?
