A few have commented on food.
Managing the last 110 mi. From mtr.
Either you can, or cant
Depends on mpd you hike. And size of cannister.
If cant, theres the packers, or resupply at onion valley
I found jmt easy to do 18-25 mpd , But factor in hrs by end of sept. Days get shorter.
Slightly higher avg miles than on AT. Trail tread pretty good, graded for stock.
I had 3 days food left in bearikade weekender out of 8.5 I started with ...and....i buried a little in catholes too. Even with a short 10 mile day on account of rain, the last half flew by, lots of long smooth downhill 10 mile walks from passes.
I heard of people running out of food, etc. Totally not my experience. But i saw a lot who stopped at 1 pm. Not sure what they did for next 7 hrs.
