Hey Scott, these are my initial ideas for training routes. The 20+ mile days can be done as single day pushes (when I feel up for it), otherwise they can be 2 day routes in the beginning of the cycle to build endurance. The Yosemite 52 miles is something I see being done over a 3-day weekend in the summer when we are on 4-tens. I would love it if you could add your own ideas to this map, I know you have a lot of knowledge of local trails, and finding loops that are not at snow elevation for the time being would be super helpful.
