Hi! No experience w/ asthma, but for weather wise for Tink, no worries about humidity! In all my DL races, there was only 1 time there was humidity and that was for the 5k that's in Sept, but even that was gone by the afternoon and gone for the 1/2. And if you're coming from the East Coast, you should be fine heat wise. It'll be warmer than winter in NY, but no where near warm for summer NY. At least for me, the past 2 years, I was in capri tights and a short sleeve shirt and was fine. If you're at 13:30 now, even inside, you will definitely be fine by 2015!
