Yeah, I was at Ali Air Base, Iraq in 2008. Not to be confused with Ali Al Salem Air Base in Kuwait. It was dry, but still darn hot. In 2010, I got to run daily in Qatar...that's darn hot and so very humid. You knew it was going to be a humid day when you went outside at 0530 and your glasses instantly fogged up :-) Now, there, I wouldn't run a 10K. My boss tried to ge me to, and I was like, yeah no. 3 miles was my limit there. No more deserts for me, though.
