Super Hot Tempo Mess

Went out today for a really hot and brutal tempo run.  Temps are soaring back into the 90s today - and it was probably already in the low 80s when I headed out.  The killer is the humidity.  Because of the heat, I decided to cheat and run into work - the first mile is all downhill - so it is a little unfair pacing, but I'll go back to running home from work when the weather moderates.  The pacing is as follows: 8:01 (?), 7:33, 7:44, 7:51, 7:40, 8:11, 8:09 and 7:54.  The 7:40 and 8:09  miles are estimated because the Strava kept running - Kun mentioned I need a gps watch that'll upload to Strava - sounds like a good upgrade.  Overall pace was about 7:50 - maybe 1:03.
