Throw on a weight vest and go UP, then up and down (with squats), the UP again. Keep doing that until you finish your last 2min interval. Then add some short sprint starts. This one is a BURNER. You're going to love it and hate it.
A downhill workout, really??? YES! Today's it's all about the DOWN ... well, at least until the bonus UP HILL part. This one is about overspeed training, while also offering a chance to focus on efficient downhill form.
