After roller blading for an hour and a half I went to the outlet malls in San Marco.  There is a Tanger one right next to a Premium one that you can walk from one to the other.  I walked them for 3 and 1/2 hours in around 100 to 110 heat.  Needless to say when I got back to our apt I went swimming for an hour.  All in all a successful weekend.
