heat

I could really feel the heat on my run yesterday. I don't think it was over 90 and yet the heat really had an effect. A 4.6 mile run is on the upper edges of what I will undertake without water breaks. I might, under some circumstances, stretch it out to 6. But since it is long-ish for a run with no water stops I need to be that much more careful about being fully hydrated before I head out.
