Hello, I am an 18 year old from Central Az who has functionally no experience backpacking, but have done some pretty extreme day hikes including Arizona's tallest mountain twice in a day, as well as other 20+ mile loops in a day, my question however is, there is a obviously this giant gap between a gnarly day hike and consistent 18-20 mile days with my pack for months. My goal is a NoBo PCT in 2028 and a Nobo CDT in 2030. I have experience outside but it's all from a climbing background which seems pretty non-transferable here. Any advice would be appreciated, do I need a reality check? Would a timeline like this make sense for someone of my level, and what should I be doing in the southwest to train my body for the PCT?
