I just finished my John Muir Trail thru hike last weekend and can't stop thinking about my next long hike. The Colorado Trail naturally comes to mind ... much longer than the JMT but not a 4-5 month commitment like the AT, CDT, or PCT. In an ideal world, I would thruhike the PCT next year but I think that will have to wait.
I am planning to buy one of the CT guidebooks soon (probably the Yogi guide) but was curious whether someone who has hiked both The CT and JMT could comment on how the two differ in terms of scenery, difficulty of terrain, trail towns, and resupply. I hiked around 14 miles per day on the JMT but had a few days closer to 18 which I felt like I could do without much trouble almost indefinitely. When I was eating well, I felt great, had no gear issues, and no foot problems to slow me down. I actually prefer 15-20 mpd to 10-12 since I get bored sitting in camp for long periods. I was usually done with 10 miles shortly after noon.
I would want to do the Colorado trail in less than a month so I think a 18 mpd pace would work out pretty well and allow for a few zero days.
The other option I'm thinking about is to hike a 500 mile section of the PCT - northbound - and repeating the JMT within the PCT segment. Kennedy Meadows (south) to I-80 would be the most likely route.
Thanks for the feedback!
