30min. spitpaint. I had this idea of some kind of runner/booster mech or suit high up in the stratosphere just about ready to burn through a course. Initially it'd be a 4-booster thrust across a straight away then the calf-mounted jets would eject and the course becomes a combination of long straights and windy obstacle-laden turns, so the pilot would have to juggle between burning jets and using their legs to help maneuver through.
Or something like that, I hadn't really thought it through much, just what was going through my mind while I was working on this.
