AM - 5.5 easy shake out miles on a warm, humid cloudy tropical feel, morning.
PM - lunchtime on the treadmill - high aerobic effort - 75-80% HRR for an hour. After an easy mile warm up I increased the speed to 6:31 pace for the next 3 miles - but the treadmill stopped and just as I was restarting it - and perhaps just before it had stopped, I felt a little off - as if I was pushing too hard. Started to put the speed back up, but thought that maybe I should just run an easy 30 mins, so I slowed the speed down to about 7:45 pace, but within about 3-4 mins I felt much better and finished out at 6:42 pace. Weird. But I take this as an interesting discovery - not to necessarily throw in the towel on a workout as I might have in the past, but noodle through a rough patch and maybe it will work its way out. Was not the best workout, but wasn't the worst. So it was a mile warm up then 7.0 miles at MP and a half mile in the middle of "not so fast."
Will keep the intensity low for the next couple of days for proper recovery.
