It looks like RunDisney has updated the information for Wine & Dine and based on what I'm seeing in that thread, I think there are a couple of items that may bear keeping in mind for Marathon Weekend, assuming RunDisney stays consistent (LOL, I know).
First off, the half marathon proof of time threshold of 2:30 introduced for the DL Halloween Weekend has been implemented for Wine & Dine. I think it's a relatively safe assumption that Marathon Weekend will see a PoT threshold of 2:30 for the half and 5:00 for the full and challenges. Potentially great news for those of us looking to establish a new PoT or if someone has one in that range already in hand.
Secondly, the PoT window for W&D closes May 1st. That's consistent with the DL Halloween race PoT window closing March 1st. It looks like RunDisney has moved to a 6 month window to help accommodate checking the additional PoT submissions. The biggest take home there is that we can expect the Marathon Weekend PoT window to close July 1st under that plan. No planning for an early fall PoT race. If you think you can hit the time, I'd strongly recommend doing it now and not risk waiting.
