I have a question about heart rate monitors. I have only been back in the water for four months after a 20 year layoff. My background was mid-distance but now I want to do 1500/1650 in the pool and plan to do an open water 5k in about six months.
Do any of you train with heart rate monitors? What sort of numbers do you look for when you are trying to build up your endurance and distance?
I measured my max heart rate in water and it was 18 beats lower than on land. So accordingly, I am averaging 70-75% MHR during my long aerobic swims of continuous 4000-5000 scy (open turns). If I mix in some random speedplay, I will see peak rates of 80-85%.
What are some typical numbers so I can gauge how I am doing? Thank you for any feedback.
