This weekend, I am very sick and sniffle-y. I slept about 12 hours last night and this afternoon, but I still forced myself to go for a run. Not such a great idea. I ended up wheezing. Not cool. Seriously, if another runner sees you wheezing, you look like such an idiot, and they can silently and smugly whiz past you in the middle of your asthma attack and keep going, feeling better about themselves and thinking of how big your butt looks in those shorts.
Anyway, moral of the story: If you’re sick, stay inside and don’t try to run at your lactic threshold. You will not feel better. You will not make anyone else feel better, except maybe that smug jerk I just described above.
