What is the "Road Warriors" workout Chris invents?

From the text:

“Chris invented this workout he called Road Warriors: He would lead us on long, killer runs through places like farmers’ fields and construction sites, places we weren’t supposed to be, and intentionally try to get us lost. We’d run as far and as fast as we could, down strange roads, through the woods, whatever. The whole idea was to lose our bearings, to push ourselves into unknown territory. Then we’d run at a slightly slower pace until we found a road we recognized and race home again at full speed. In a certain sense that’s how Chris lived his entire life.”
