This may be a dumb question, but are the Dooney & Bourke items pre-purchase? They are listed to be picked up like the commemorative pre-purchased items.
What site do you go to to pre purchase them?
You can either pre-order them or wait and purchase at the expo. Either way, they need to be purchased at the expo (unless there's a production delay like there was for the 2016 weekend...see below). If you pre-order, you do so under your Active.com account - log in and go to My Events, then Purchase Additional Merchandise. The bags will be there (whenever they are posted...I just looked and don't see them yet).
The advantage of pre-ordering is that you will FOR SURE get the bag you pay for. However, when you pre-order through Active, you need to pay additional Active.com fees, similar to what you pay when you register for races. So you'll be paying the retail price of the bag + tax + an additional 6.5-7%. In the past they have let annual passholders/
DVC members return and re-purchase the bags at the expo to apply whatever discount the person is eligible for (I did this in 2015 to apply my AP discount), but I think they are doing away with that...and if you return and re-purchase, you don't get the Active.com fees back.
On the flip side - if you don't pre-order and choose to wait and buy at the expo, you don't need to pay the fees. But you could show up and the bags could be sold out (this is often the case with Princess - sometimes certain styles of those bags will sell out on day 1 thanks to personal shoppers, eBay-ers, and occasionally runners who arrive early...ahem). If you 100% MUST have a bag - if you would be devastated to miss out - I would recommend pre-ordering so that you know you have one. Either way, you get to pick your pattern placement. The CM/volunteers selling the bags should give you 5-6 to choose from. If they don't, ask nicely or try again later with a different CM/volunteer.
Normally the bags for the January weekend are not the most popular (I have my theories as to why but I've already rambled on enough about purses...) and actually end up at the outlets later at a discount price. But for the 2016 race bag there were delays in production and the bags were mailed out in March, so everyone who wanted one had to order. So we'll see what happens this year.
Not sure my thoughts are worth much since this will be my first marathon. Just had a talk with my mentor b/c I'm panicking about being swept. My long runs are at "you'll get swept" paces, but they are long. Done 18, 20, 23, and am doing 25 this Monday. My mentor says that I have to stop trying to run them at 15mm, which leads to 18, 19mm for the miles after mile 15, and just do them all at 17 (my magic mile is 11:40). She's an experienced marathoner and keeps telling me time on feet matters more than pace. I"m believing her!
I think you will be fine! I agree with your mentor that time on your feet is super important in training.
2 things to consider that will help you out on race day:
1. Adrenaline - the event you have been preparing for is finally here, you're surrounded by thousands of other runners, Mickey is there, etc. This will give you a boost!
2. Your corral. Unless you are the very last person to cross the starting mat, you will get some kind of time buffer. The "sweep clock" does not start until the very last person *starts* the race. So if you start, say, 30 minutes before that last person, you get an extra 30-minute buffer (see above for an extreme example).
