Hello everybody,
I'm a 14 year old looking to thru-hike the Tahoe Rim Trail this summer (solo). I wasn't sure where to post this, so I thought this topic was good, even though I have been backpacking for a lot of my life, and have been on several multi-day hikes (though not as long as the TRT). I was wondering, for me, a 14 year old male, 5'7", 110 lbs (I'm a bit underweight, I know, I'm trying to work on it), relatively physically fit, what kind of weight I should be carrying, and how many calories per day I should be consuming to maintain my current weigh (plus or minus a few pounds). Any information would be helpful.

Thanks!
