Just curious... would it be okay to do sprints to failure (either breath, or muscle fatigue) then wait like 2 minutes to recover, then sprint again. I did this theother night, four times. It was sort of like a pyramid, the distance I was able to sprint decreased each time. I do it on winding, rough-terrain bike trails... it's kind of hard to measure the distance.
