Suicide sprints are simply running from one line to another and on each sequential run the lines get further apart. For example, on a football field, start at the end zone. To complete one pass, run to the 10 yard line, touch it, and run back. For the next pass, run from the end zone to the 20-yard line and back. For the next pass, go to the 30-yard line.... And so on. The lines can, in reality, be as far apart or close as necessary. The reason they are called suicide sprints (or just "suicides") are because you end up doing several sets and you quickly want to stop or even "die".
