Thanks, Karl. Can you tell me what % of Max HR your 180 was? Also, you say it was pretty much pegged at 180 for most of your ascent. Did it decrease much when you walked? Thanks.

My n=1 for PPM, but my HRM was pegged at 180 for most of the ascent. Not a comfortable place to be. Dropped to 160's as soon as I turned around at the top. I am a flatlander also.
