Series: Typically used in track training this technique involves increasing the distance of a set until a maximum distance is reached.Then the sequence is reversed. Example: 1@ 100 yards, 1@ 220, 1@ 440, 1@ 880, 1@ 1 mile, 1@ 880 , 1@ 440, etc.Also referred to as staircase or steps.Can be very effective and is harder than you might think,especially when you assign times to it, and do multiples.Good Luck.
