There will be one last Mare-A-Thon before My Little Pony: Friendship is Magic ends. Brony TV is doing something similar on Friday, with a Season 9 Mare-A-Thon, but this seems to be the Mane Event.
 
The MLP Anniversary channel by 4chan on CyTube is doing a massive, all-inclusive Mare-A~~Thon of My Little Pony: Friendship is Magic, with all episodes from S01E01 ~~ S09E26 (livestreamed from Discovery Family when it airs), the Movie, “Best Gift Ever”, “Rainbow Roadtrip” and all MLP: FiM Shorts. Interspersed with random pony videos and pony music, including episode-related content, via generous, pre-calculated buffer times that ensure that we get to see everything. They also try to live-stream the documentary “A Decade of Pony” from Discovery Family on Friday, or if that isn’t possible, will show it later with a copy.  
The celebration starts today at 3 PM EST and the full schedule of everything is here:

I’ll be attending there when it starts and you should, too. This is the last time to watch My Little Pony: Friendship is Magic together with like-minded pony lovers on livestream in a dedicated pony stream channel before the show’s Grand Finale.  
Be on CyTube when it starts and let us make the most of that:

One last note, please don’t tag this with “End of Ponies”. I realized a few days ago that the tag is rather premature, as the official comics will not only continue for a while, put likely even for a very long time since Hasbro wants to continue MLP: FiM with a Season 10 in the official comics. Which also drastically increases the chance that Generation 5 will be a Friendship is Magic sequel.  
The ride will not end just yet.
