shit bag tired
When you're training for an endurance race (like Ironman or long distance ultra runs or ultra-swims), with non-stop training, you drag your ass out the door... Every.Single.Day. to get the training done. In the moment of the training, you're in your glory, but when it's all over you could lay down on the ground and fall asleep in less than 30 seconds.
I finished my 3 X 3 mile training run at race pace that started with a two mile warm-up and finished with a two-mile cool down. I'm so shit bag tired, I could lay down in the middle of this sidewalk and fall asleep right away.
