Four mile swim

Another day of high humidity running.  Did 40 minutes of short intervals and finally found a good pace 2.5 miles in.  I need to get back to higher intervals, but the heavy air is killing me.  I'm also still trying to get used to running with a CamelBak so I don't want to push too many long intervals and spend my time hurting.  I need to start running later in the day anyway, but it's hard to do those long distances at dinner time.
