Good info on this thread!
I did the trail in late August this year, fast and light. It was a great experience. Might have to do it annually.

I was wondering if you plan to carry all the food, or have a few resupply drops. Although I saw (most) backpackers lugging huge heavy packs, it is possible to do it carrying no more than 3 days food. Takes some planning, maybe a little help, but it would potentially speed up your trip from 11 days to 9 days, maybe less.

Actually with such a low base weight, if you are in reasonable shape and not overloaded with food/water, you might get your 9-10 mi done fairly early in the day.

It seemed to me that Park officials advised people to take longer, carry more, and go slower, which they judge is a safer approach for your average (unfit) urban park visitor.

But if you are fit and experienced .....you can do better.
