If you love to hop on a treadmill and just run, try this Pyramid Workout to spice things up. Changing up your pace is great for the body and makes things go by faster! It will also make you a better runner. This is challenging yet very doable. If you are a hard core runner this might not be challenging enough. But the MPH's are just suggestions. Make it faster or slow it down if you need less or more. This will give you a little over 3.0 miles when finished.
