Notes
20s hill sprints with walking recovery. Google Earth says they are about 116 meters. GPS says they are about 106 meters. I think I believe GE, but it may be a timing thing where I'm not getting the end-of-interval alert until some time past the end of the measurement. Anyway, I think they are in the 4:30 pace range.... ish. The little hill makes them nice. :-) Not too steep, but adds a little more resistance.
