what gives ME the right?

I ran a 5k race this last Saturday. It was bloody hot! It was in Virginia Beach...I did decent time. So therefore I then proceeded to consume a large amount of "cold brews" throughout the day and well into the evening...technically then Sunday. As you can imagine then SunDAY was a waste. It is as if the day did not even happen. I slept for most of it. Took a shower around 2pm and drove about 4 miles to have dinner with some friends. All of which completely exhausted me. After which I then got back in bed...watched a FILM and moved onto more sleep at about 8:30pm. What gives me the right to do such a thing to myself? Because I ran a lousy 3.1 miles? Unacceptable and yet I did it. Why is a question in this area I fear I shall never be able to supply an answer to. Alas, I then ponder do I need to? Does it really matter? I mean one could deduce that if one ran said miles - got up at 5am (half past way fuckin too early to be up a Saturday kind of time), sucked on some Gu (don't ask if you don't know!), ran and sweated for 30 minutes (be careful here people if you have any comments on my time...and you are sitting where right now drinking A what? ahem!), does that not make it OK to then inhale beers? Or at least even it out a bit? I am not sure and really I have moved on...
