P. F. Chang's Rock 'N' Roll Arizona Half Marathon

I never did more than 10.5 before my first half-mary (ok, I've only done one).  If you're doing 80-90 per month, I'm sure you'll be fine. I'll be doing the Fiesta Bowl 1/2 in December and then the Chang's 1/2 in January.  Good luck!

teachertrek - it sounds like your training is right where you need it to be to finish the 1/2.  If you're going 10-11 in your training runs, 13 on race day is completely doable.  You even have a chance to increase your mileage a little before January if you choose to do so - that will allow you to finish even more comfortably with a better time.  If you increase the mileage, just remember the 10% rule - slow increases lead to less injuries.  

 I am training to do the full (the 1/2 last year was my first) this January- if I can stagger over the finish line sometime between 5 and 6 hours, I'll be happy

Your pace on the miles loks good, but I don't know what your goal is.  My longest was. 10.5 before the half an I was fine.  Think of it this way - - it's only a 5K more than you've already run (10mi + 3.1). 

There were nearly 10,000 at the Disney 1/2 and it seemed to thin pretty quickly - although the first 1/2 mile was dodge left/dodge right.

PF Chang's was really cold last year - - buy some cheap clothes/goodwill that you don't mind shedding and losing (just in case)

Brrrrr !  Sounds like a cold start last year , 

What are the typical temperatures between  10 am and noon ?
