In 2000 in was unusually warm-70+ by 10:30. I too went to Hartford after a crowded NYC in 1999. Be careful-you can go out too fast. The course is relatively flat (miles 3to about 17 are an out and back loop)until miles 22-25-at this point you get some rolling hills that will wack you. Support was good and race was well organized. I would return.
