to me it sounds like you live in a place that is harsh this time of year. personally, i draw the line at a heat index of 100. if it is 99 i will ride. but if it is over 100, then i will alter my schedule and go inside on the indoor trainer. and yes, i also think you are fast, but unless you arent drinking large amounts of water while riding in that kind of heat (like 2 liters/hour!) then you are playing with your life. seriously, your hot-weather riding skills should be bulletproof to ride like you do in that kind of heat. otherwise, you will pass out while riding. if you are unconscience and no one is there with you, well, you get the idea. be smart.
good news, however, is that you probably have a strong base from your other sports. if so, then you should pick up cycling quickly. i very much recommend getting The Cyclist's Bible, The Ultimate Ride, and Serious Cycling. a good nutrition book couldnt hurt either. also, come here and ask Q's. the people here are very experienced and trustworthy. as fellow cyclists, we wont advise into the wrong direction. but if there is one thing you need to know, it is this: know yourself.
