Well, I don't have the time anymore, but around 2 years ago I watched Eureka Seven from episode 12-50 and that was around 15 hours.

Well, that depend on what anime it is... So far the hours I have watch was up to 5 or 10 hours... Cause why waste all those time when you can get-up and get some fresh air outside...

When i first started watching Naruto Shippuden, i was 21 one episodes behind so i watched episodes 1-21 in one sitting.

I went almost two days watching all of blood+ and half of xxxholic only taking breaks to use the bathroom and eat, I know its not something to be proud of but i couldn't stop watching

Last Exile Marthon From 1am-1pm....:)

Here's CHI!
 

Umm How long You have watched anime In one sitting Umm...
Ouran High School Host Club episodes 1-19 all in 1 DAY!!!:rheart:

I was really sick during the summer and watched like 18 episodes of Death Note on top of the entire fruits baskets series. I slept a little bit but the sickness kept me awake so I used the animes to keep me up...totally worth it :p :) My two faves so far

I once watched on youtube naruto for 3 hours straight :D

The most I've done is watch an entire 26 episode series in one sitting, from night until morning...about 11 hours or so probably. Can't believe some of you went for 24 hours or more though. I don't know if I could possibly be intrigued THAT greatly to spend so much time in one position D¦

The whole Outlaw Star series, it took me all day, with breaks for needless things such as food.

tough competition!

Hm....I would have to say Fullmetal Alchemist I watched all the episodes and the movie too :puccasmile:

around 30 hours while watching the rest of season 3 and 4 of Naruto

Woah well i gotta say..
 

In one Sitting i'd say 14hours back to back of Naruto and Bleach (when i first discovered Anime)

Now i have my own library at Welcome to ps3anime.com for those who wanna watch it on ps3 or PSP only!

Woah you must have had some bags under your eyes LOL even then i bet you craved for more orr fell asleep! ;)

about 13 hours... lol... good times :_)

7 hrs a day for about 4 days trying to catch up with Bleach.

I can only watch for, at the longest, about 3-4 hours. But I usually do something else to take a break, then resume watching whatever I was watching =D

I'd say 5 to 6 hrs tops

8 hrs straight. Do not even remember what I was watching. We just hooked my computer up to the tv and started watching.

I've watched 6 episodes of my favorite anime, Kamichama Karin, straight... And just recently, Me and my best friend sat through 4 episodes of Higurashi no Naku Koro ni.

not really i used the christmas holidays even though i had two weeks of almost insomnia after school started which was well not that good

I think it was around 8 hours straight, then my stomage rumbled (I want food) ^^

SAMEEEE just after my exams i spent all my time watching the wallflower, shuffle, Princess Princess and Kiminozo.
Yeap... i had a good break ;]
haha

I've watched anime all night long, so that's about.. 12 hours or so xD Nolife FTW!

About 7 hours straight, I never turned away from my computer monitor, except for pee breaks.

lol i used to do that
when i use to watch anime XD

NO LIFE FTW lol

Hehehe;;;
I don't know if I am a maniac, but, 4 years ago, I bought 12 cokes, 6 big macs and spent 38 hours watching Naruto. After that, slept for a whole day.

14H only stopt a few sec to get food

I watched Ranma 1/2 for 5-6 hours... but I watched j-dorama (It was Proposal Daisakusen) for 7 hours... at last we ( I watched with my twin-sister and older brother xD) were to tired to close the computer and beside I had to wake up early next day.

Me and my friend Andy, when i first found out about DBZ..we stayed up for about 3 days straight watchging it at his place, I got pretty damn tired once we watched all of it that he had xD

I watched the whole series of Fruits Basket in one night, with maybe an occasional bathroom break. About 9 hours +_+

I don't know how long it was, but I watched all three seasons of Aria at one time.
:rheart::rheart::rheart:
and yes, I cried at the end...I always do with Aria...:rheart:

Once, my sister and I watched a dozen episodes of InuYasha in one sitting. We had rented three volumes without knowing that there were four episodes on each one. (For the season before that, there had only been three to a disc.)

Not much, I guess, but it's the longest marathon I've had to-date.

2 day marathon of bleach...since i really neede to catch up..and watched the filler episodes too
-.-

I think it was about six hours. I was trying to finish up the rest of Full Moon so I could go on to another anime. I didn't know if I was crying because of how sad it was or if it was because I was so tired because I had stayed up so late. XD
~C ya
:D

All of Gundam Wing in one sitting X___X;

Several hours, I can't even remember how many! I remember...I finished Ghost Hunt and Sukisho in one sitting...which was...35 or 36 episodes...
I saw episodes 7 to 15 of Death Note one day...then the next day (or the same day/night...I don't remember)...15 to 22...and then 22 to 32...
I watched up to episode 18 in Lucky Star one day, then finished it one night.
I spent a whole day watching Clannad, but I only got to 13...I was watching Genshiken before that. And this is all if no one (someone can, its not like I'll listen :rolleyes:) bothers me.

I have a challenge for myself...for six different anime...

Katekyo Hitman Reborn
D. Grayman
Eyeshield 21
Prince of Tennis
Fullmetal Panic
Case Closed (Detevtive Conan)

And that challenge is to see how far I can get in each one for one day. Yep. No bathroom breaks, no eating breaks. Just me, my computer, and I...what a stupid idea...
