So drained, even my girlfriend can't keep me awake anymore.

"Weight training causes micro-tears to the muscles being trained; this is generally known as microtrauma. These micro-tears in the muscle contribute to the soreness felt after exercise, called delayed onset muscle soreness (DOMS). It is the repair to these micro-trauma that result in muscle growth." -wiki-ed

Freaking legs are so sore, it pains just to take off my pants.
Had a discussion with someone, on whether the ache/sore felt in our legs from running like hamsters were caused by lactic acid or micro-tears.

"Although it may seem counterintuitive, physical improvements to your muscles and cardiovascular system do not occur while running. Improvements occur between runs, following the stimulus of running. In other words, if you don't give yourself enough time to repair after a run, you will actually get slower and eventually injure yourself." -(a)

really?!? we had run training freaking 6 days in a row. My legs were still ache-ing like mad before each training.... lol

"When we run longer, steeper, and/or faster than usual, micro-tears (small rips) occur in our muscles (as well as other metabolic byproduct damage), resulting in temporary soreness and dysfunction. In small doses, these micro-tears are good because they force our bodies to repair with more tolerance of speed and endurance for the next run." -(a)

Alright, so it says mirco-tears do occur in our muscles, along with other metabolic byproduct which i assume to be lactic acid. Well googling around more...

"On the contrary, lactic acid only accumulates within muscle during relatively short, highly intense exercise such as sprint swimming or running. Endurance athletes, such as marathon runners for example can have near-resting lactic acid levels following a race despite being exhausted " -(b)

20x400m sprints and 43x10s steep muddy slope runs can be considered relatively short and highly intense right? sigh so tired, bound by shadows.
