It is going to be a very long WrestleMania weekend.
First, the Hall of Fame will air live on the WWE Network. I'm unsure how long it will last but I'll hazard a guess that it'll be around three hours or so.
The next day - WrestleMania Sunday - will be a marathon. There's a two hour pre-show on the Network before the pay-per-view, the PPV is going to be four hours long and then the episode of Monday Night Raw a day later - which is usually the best Raw of the year, will be over three hours in length.
It looks like I'm going to need to take a lot of afternoon naps in two weeks!
