To AndiBaker,
It really depends on how you use the treadmill. But you can get the same results doing a tempo run once a week on the road. Warm up for a mile, run at something just a little slower then 10K pace for 20 minutes, then cool down for a mile. If you want to work on form with some speed, add "strides" to the end of one of your regular runs. These are short pickups of 50 to 100 meters at maybe 5K pace, with plenty of rest in between. Start with 3 or 4 and add 1 each time you do them.
