Ride home yesterday was hot, luckily without much humidity although-that will come today. After being passed by a roadie (I was riding at a moderate/easy pace), I decided to catch a draft and maybe get home (and out of the 98 deg heat) a little sooner and easier too. Near the airport he dropped off his pace and slowed drastically, I was expecting a turn, stop for mechanical, or maybe he just didn't want someone behind him. I slowly pulled around and in front then thought I'd better see if he was ok. I gave him the thumbs up and he replied likewise so I kept going thinking that the heat must have gotten to him but that I was doing surprisingly well. Well, that only lasted for another few minutes, all of a sudden I lost all steam and my legs felt week. I wasn't in danger of dehydrating or passing out but maintaining a moderate (probably) 15-16 mph speed was tough, the few small hills that I encounter were tough too. I got home ok and promptly drank my Endurox and got in a cool shower. I was a little nervous about the heat and, I guess, with good reason, it really takes a lot out of you. Today should be even worse so I'm going to be extra careful.
