Marathon Week usually takes place during the last week of May, and during marathon week all liquids must contain alcohol. You start drinking once you wake up on the last Monday of May and you cannot drink anything but liquids containing alcohol until the last day of May (unless you have to due to a medical emergency).

You cannot drink ANYTHING that does not have alcohol in it AT ALL! YOU MUST DRINK ALCOHOL TO BE PART OF MARATHON WEEK!

Be warned Marathon Week is not for the weak of liver.

Get the Marathon Week mug.
That awful week when you have to take an exam every single day. Which means you have to study every single day for the exam of the next day. Known for the constant headaches, few hours of sleep and for being extremely tiring. The constant daydreaming of Friday night, which means you won't study anymore, is totally normal.
Sarah: Hi Kevin, wanna go to the movies on Saturday afternoon?
Kevin: You are kidding right? I can't, I have exam week marathon next week. I must start studying now.
