On occasion, I have difficulty breathing in high altitude...
I'm not sure how to deal with this but...
1) In Aspen, I had to come down from the peak because I was having issues with catching my breath
2) I was in Jackson Hole last weekend and again had difficulty catching my breath till I got closer to base
Both occurrences were due to probably more exertion. For example, I got stuck in powder while riding through tress in Jackson Hole. By the time I got out, I was essentially hyperventilating. I wasn't able to finally catch my breath till I got to lower altitude.
I know when I was at Breckenridge 3 seasons ago the stores would sell oxygen in a can but I'm not sure if that sort of thing would work?
I could just that I'm just out of shape and that's what causes the shortness of breath.
Anyway, wondering if others have similar issues and how they deal with it.
