Hills can be brutal sometimes, but I actually prefer to have changes in elevation during my runs just to get different muscle fiber recruitment. One of Atlanta's running slogans is "heat, hills, and humidity" so I am never lacking in hill training! Though I could do without some of the humidity. :) Great run! Hope you feel awesome for race day!
I know how you feel about the humidity. I live in Mississippi. Summers can be very brutal for running!!!
