I've been off the trail for a couple of years but looking at continuing my section hiking this summer where I left off -- Hot Springs to Erwin (or reverse). I'm thinking

Day 1: 16.3 miles - 273.7 Hot Springs to 290.0 Log Cabin Drive
Day 2: 27.6 miles - 290 Log Cabin Drive to 317.6 Sams Gap
Day 3: 24.5 miles - 317.6 Sams Gap to 342.1 River Rd (Erwin)

I've done a half dozen or so 30+ mile days in my sections from Pen Mar to Erwin, all unsupported. This hike is a slackpack. Anything out there in this section that makes this itinerary problematic? Is it doable for an old man with car/hotel support at days end? The splits are designed with pickup/drop off in mind.

Suggestions?
