I loved these too! I just did my first marathon on Jan. 15, the Houston Chevron, and have been recovering the past 3 weeks with short runs and walking. I went out today for an easy 6 miles and ended up doing 8 because it just felt so wonderful!
One thing that puzzled me was the beer station around mile 21 or so. I couldn't imagine anyone wanting a beer at that point. I had no idea it helped with the lactic acid buildup. I felt like such a dummy!
