Hi,
Yesterday I did a steep ascent (35%) in the snow (300m elevation gain) after another 1000m elevation gain without snow. During the snow ascent, my HR was way above my AeT (165 bpm) even if I climbed very slowly. I was literaly out of breath and had to take my breath every 30 seconds. But my legs didn’t burn.
What’s the problem? Good muscular endurance but low aerobic fitness?

Best,
Paul
