You cannot mess up a fartlek run. It is all about changing it up. If all you do is practice running slow over a long distance that is all you will ever acheive. Your pace will look slower with the ups and downs. Getting those faster muscles to work in sync with the slow twitch muscles is the key. Run fast for a minute, recover, rinse and repeat if necessary. Or try running faster for 5 minutes, recover, speed up for 4 minutes, recover, 3 minutes, 2 then 1. If you dont trust the benefits, check your best times and see if they improve. I like a standard 2 mile timed run over the same route. Test your time every couple of weeks. Your times will improve. With more speed comes less need for endrance anyway.
