they are essentially metro areas that are significantly warmer (1-8 degrees) than their rural counterparts. most of them are this way due to little tree cover. trees provide moisture as well as shade, which contributes a cooling effect.
three guesses which city is the fastest-temp-rising, hottest-city-of-the-summer, headlining-heat-island? the first two guesses don't count.
that's right. Louisville. apparently it has one of the lowest urban tree coverage percentages, around 28%. Atlanta's is nearer to 60%.
SUPERYAY for marathon running in a heat island in the middle of the summer.
seems like IMLou 2013 is shaping up to be HOTTER than last year. and last year had Lou's highest DNF rate at 14% (also a 14% DNS. that's 28% of people who signed up that didn't cross the finish line!)
i'm sincerely hoping that my genetic makeup somehow remembers how to handle this kind of ridiculous heat. i was born and raised in the south. played 3 soccer games a day for 3-4 days in August tournaments, with temps in the 100s and humidity in the 90s. in our last year in atx before moving up here to Yankee Land we had over 100 consecutive days of 100F temps.
at least Boston FINALLY got the memo about summer time:

you may also notice from my fancy iPhone screen shot that there are tiny thunderstorm icons for Tu-Th. those icons actually stretch all the way into next week. looks like stormy weather for the 70.3 weekend. if it does storm, my two training triathlons for Lou will have been in the rain. such great training for a hot, humid, dry race :/
at least it'll make me tougher. right?!
Don't tell me this! The heat is hot enough in ATL, but you're saying it's just going to be hotter in Lou! Yikes! Better get the heat training in. Maybe we'll end up walking the marathon together. :)
