Classic Ski 25:00 
5x5 intervals, about 3min rest between. Started on Phils, just past where upper UW comes in, around Tie City, and back on Phils (no Gobi). Finished on top of the little rise after the tight turns almost exactly opposite the start location. Tracks were set, which made the skiing most enjoyable. Pace was quite consistent, but last 3 were maybe 10m shorter than the first two.
