re heart rate- i don't track mine so much but i check the graphs on my phone after.
but my watch is shit- just shifting position of the sensor changes the reading by 30bpm, and it depends on how sweaty i am and stuff- so often i see a precipitous drop in heart rate after a few mins literally cos i started sweating. its annoying cos it fucks with my VO2 max estimate and will sometimes tell me that really hard runs were not productive for improving my fitness cos it was readng my heartrate way lower than it was.
hardly any running for me this week. i slightly hurt my ankle on my long run last weekend. i've attempted to go out twice just for 5ks and quit one after 3k and one after 2k because it was starting to really hurt. walked into town today and had to get the bus back cos it was starting to hurt.
getting a bit stressed about it tbh, in my head taking a week out means i'll lose a lot of what i've built up but i know i will injure it worse. its also in a leg that i have an old knee injury in, and making me walk funny so that's flaring up. sucks tbh but i've got a bandage compressing it, elevating it, and will be resting it for the rest of the day. tempted to attempt another 5k tomorrow but with what its like now i know i shouldn't.
