I’m sitting here contemplating my navel about the fact that I have attempted to summit a 6000 meter trekking peak 4 times, unsuccessfully, the last time 2 years ago on Chimborazo when I was 64. I made it to high camp 3 times (including Mera at 19.21k ft.) but turned back due to exhaustion twice (and conditions once). I swore off trying again, but here I am at 66 thinking about another go.
I’m an avid cyclist and occasional runner. My endurance is not a problem and I’ve done my share of suffering. I’m 5’10”/160 – but could probably drop 5-7 lbs. I’ve trained pretty hard for my other trips, and used a hypoxic tent. I could probably up my training 25% or so. But I’m not sure anything will get me over the hump of being laid low over 18k feet.
How do I know if I’m at the limit of my physiology?
Is it possible to improve high altitude acclimatization and performance? Is there a best thing/best way?
Any thoughts would be appreciated.
