So I went for a quickish run yesterday and noticed the following with my HR and was looking for some thoughts…
ran the first 10 mins slow as and HR built up to around 165
ran the next 30 mins ‘hard’ (breathing heavy) and HR sat at around 175-180 for the whole time.
ran the final 30 mins slow as but HR stayed around 170, despite being able to chat happily and not at all out of breath. HR only came down at all when I came down to barely a jog.
I’m 43 years old, so my max must be somewhere around 180. Is it normal to be able to maintain that high HR for so long or is it just an indication of lack of fitness?
<div>I’m fairly new to running but given I can happily run for a couple of hours at 10 min mile pace, I’m clearly not completely unfit (although very slow), so not really sure what the deal is?! </div><div>
