Treadmill Workout

I needed a quick 3 mile treadmill workout, that would get the heart pumping, the blood flowing and the sweat dripping and this did it.  Enjoy

Minutes Speed 0-5 5   5-6 6   6-7 6.5   7-8 7   8-9 7.5   9-10 8   10-11 8.5   11-12 8   12-13 7.5   13-14 7   14-15 6.5   15-16 6   Repeat again   3 miles in under 30 minutes!
Pretty simple but I like interval running and this didn't bore me
