Aerobic Running vs Aerobic Swimming
Hey everyone! I have been training for triathlon for a couple years now and have really gotten into Zone 2 training to increase my aerobic capacity specifically for running. I am wondering if anyone uses the same strategy for swimming. Essentially, you run at a low HR (180-age) for extended periods of time using mostly your aerobic systems instead of going anaerobic.
I am curious if it translates the same way to swimming because your spending seconds holding your breath at a time and unless I am sprinting, I rarely get my heart rate that elevated while I am swimming...
Just want to have a discussion especially because a lot of people on this forum have done swims that are 10km or more.
