I am an Appalachain hiker, If you have ever hiked out east, you know that, it is very rocky, and even though it is not as high, here you can still have elevation gain/loss of 2,000-3,000 feet daily
out here I can hike 25-30 miles a day, but I think even with elevation, heavy pack, and terrain of the sierras, I could hike 20 miles a day. But I will probably train over the summer on day hikes with a heavy pack to get used to it.
I consider my water purifacation tabs as a consumable, and my dad will probably carry maps, and compass and guide book, because he is an expert in all things navagation. But I will have a garmin GPS with a load of waypoints to keep me on track
My Golite jam carries 30lbs pretty well, so I am not concerned about comfort. I will be posting a mock meal plan later for you guys to help with
I am not positive on the trails ccondition, I read someones trail journal an the internet and they said it was very easy to get off course, and they hiked half the time off trail.
Here is something I got off the comp.
The Tahoe-Yosemite Trail does not have the same type of pedigree as the Muir Trail, which was publicly established and constructed early in the twentieth century. The Sierra Club and the U.S. Forest Service discussed the Tahoe-Yosemite Trail around 1916 and worked on the trail around Meeks Bay and around Echo Lake, but they did not formally establish it. The Tahoe-Yosemite Trail evolved informally and unofficially in hiking and conservation circles. Outdoor author Thomas Winnett eventually brought the trail before the public in 1970 after he and others personally walked, measured, and researched the route. His guidebook contains maps, measurements, history, and advice, so backpackers and hikers can enjoy the trail.
and another description
The Tahoe-Yosemite Trail winds its way along the crest of the Sierras, sometimes paralleling the PCT, and sometimes sharing the trailway for short distances. The trail passes many of the High Sierra's lakes, and passes through the Desolation, Mokelumne, Carson-Iceberg, and Emigrant Wilderness areas. Highlights of the trail include Emigrant Meadow, the "Benson Riviera", and the northern Yosemite high country, along with many other attractions. The trail also includes route finding over St Mary's Pass through high alpine meadows, and sometimes difficult trail routing along Lost City Creek.
The Tahoe Yosemite trail isn't an official trail such as the Pacific Crest Trail or the Appalachian Trail. Its existence is due to a book written to describe a route in the Sierras. The Tahoe Yosemite Trail book is written by Thomas Winnett and is available at hiking stores or over the internet. The trail receives no funding for maintenance except what any other trail would receive.
