Six-Pack of Peaks challenge… In 6 days in October?

Hey, We're thinking of doing the 6-Pack of Peaks across 6 days in October. We're experienced mountain hikers. I guess I have a couple of questions... 1. Apart from having very tired legs, is there any reason not to do 6 peaks across a week or 10 days? 2. Will all the trails be walkable in early Oct? 3. Do any of the trails require specialist equipment? We have decent, worn-in boots and walking poles, and don't want to do any climbing etc. Thanks for any advice you can give!! Dan
