attempting heat acclimatization

I've enjoyed sleeping in a bit during the last few weekends, pushing my riding and running from cooler early mornings to sweaty midday workouts. I thought perhaps this might help me get used to the heat, so that my week long visit to my sister in Orlando wouldn't be such a shock. not so. The heat and humidity down there was suffocating. True, my 2 year old nephew wore me out, so I was tired & sleepy anyways, but merely standing outside caused you to drip in sweat. I did catch a short run one evening after one of the daily afternoon thunderstorms (I finally caught on that it cooled down a few degrees afterwards)... but it felt like I was breathing in pea soup. This is one of the reasons I don't live in FL anymore!!
