My calendar says it's time for another one of my Q workouts... and, um, instead of my intervals being at half marathon pace, I guess (according to Daniels) they're closer to my 12K pace.
But whatever. I'm taking the day off- not because of mental fatigue, my more typical reason for wanting to take a day off, but because a few different signals my body's giving me that it needs a break.
Waking up after five hours of sleep when I could sleep in. Unquenchable thirst. Vague pains which only barely make it to conscious thought, but taken with the others are signs as well.
Hopefully not too little too late...
