argh so i had what felt like a great run, but my watch app is telling me it was extreme and that i could have injured myself. but, it was an easy distance for me and i wasn't pushing my pace. in fact from 8 km onwards it kept warning me my heart rate was going into the dangerous zone, so i slowed down a lot. i wasn't breathing too hard or anything.
chart is here:
usually my watch massively under estimates my heart rate (i know this cos it quite often starts out ok then drops off a cliff, despite my pace being the same, i think sweat effects it lol). so it would be weird if it suddenly started over estimating it.
basically do i listen to my body or do i listen to the app? i don't want to damage myself but i can't see how doing a distance that i'm confortable with, at a slower pace than usual, can be bad for me.
for reference, last time i did this distance my app said it was in the 'improvement' category for aerobic training, with no anaerobic impact. this time it was 'extreme' for aerobic and 'improvement' for anaerobic. only really difference between the two runs is it was a couple of degrees warmer today.
god this app is tyrannical. i love it cos it helps motivate me but i don't like being told that i'm injuring myself. and sometimes it tells me to go to bed earlier when i fucking did but just couldn't get to sleep!!
