Sleigh Bells - Infinity Guitars

One of my new favorite running songs...perfect for a treadmill speed workout.

I'm not a huge fan of the mill, but it is a great tool for speed workouts in the winter. 

Here's how I roll: during the chorus, I pick up the pace to what I like to call puke pace (the fastest you can possible run without puking...for me that's like an 8.5 on the mill), then recover at a higher than comfortable pace for the rest of it (my normal pace is 7.3-7.5 on the mill, so higher than comfortable is somewhere around a 7.7).  Repeat!
