2 years ago, when I was 75, I hiked the MWMT to the top....
Last year ... I completely ran out of gas at about 13K ...
burtw,
Are you sure that this is altitude related?
Are you OK when you are hiking a trail with the same mileage and elevation gain but at a lower altitude?
I just returned from a 4-day backpack in Humphreys Basin ...
I am still hitting a wall around 12K.
Have you ran out of gas at the beginning or at the end of this trip?
Do you have any experience with longer trips that should have provided better acclimation to altitude?
I am about twenty years younger but twice had a similar experience - I ran out of steam around Whitney crest. In both cases I turned back using a coming thunderstorm as an excuse.
In both cases I spent two nights at higher elevation for better acclimation.
Similarly, after spending a night at a Leadville motel I ran out of gas about 300 ft below Mt. Elbert summit, but was able to reach it hiking slower.
I am not sure whether this is altitude related or not.
I had a similar experience at a lower altitude when attempting a Great Range traverse in Adirondack.
It might be due to a combination of a distance and elevation gain.
I would like to figure out a root cause and a way to address it.
I hope that considering my "young" age I still have a chance to partially alleviate this issue using a proper training.
Harvey,
Do you believe that there is a way to figure out why I was running out of steam (e.g. by using such devices as heart rate monitor and blood oximeter)?
P.S. I live and work at a sea level.
