I hadn't done intervals since the beginning of the month, so I was happy to have a slightly easier workout for them today.  This was meant to be the race week workout in the book I've been using, so I only had to do 6x400m but with 60 seconds rest.  The rest was a real killer.  I jogged the first rest, but after that I resorted to walking as I needed every second to try and get my heart rate down.  Sadly the best I could do was to get into the low 150's and by the end, I couldn't even get below 160 during the minute rest (my 60 second rests had an average bpm of 170 by the end).  Cooler days should help, or if I could just get my ass out of bed a little earlier :-)

In order to get out the door sooner, I skipped eating breakfast and just went ahead with the run.  This didn't seem to bother me too much, so I think I will start doing it more often, in order to save myself some time.
