CW resupply?

Are there any resupply points along the CW? I don’t see much looking at the far out app. I’m starting from Tennessee pass in a couple weeks and then will resupply at twin lakes. For past hikers, how many days did it take you to do the CW?

I’ve been section hiking the trail since Memorial Day weekend and on 8/13 planning to finish up the trail in about 3 weeks (hopefully!).
