I think the other comments covered it, but let me repeat that pacing yourself is super important. if you have a smart watch then there are running apps that will watch your heart rate and tell you when to speed up or slow down to keep you in cardio without making you feel like you’re going to pass out.



I had a Samsung smart watch when I started running. the default health app had a coach for running that would direct your pace. I think Apple has something similar for their smart watch, but IDK for sure. Garmin of course has a running coach for their watches, since they are tailored more towards people with active lifestyles. but their watches are also somewhat expensive.
fitbits these days are mostly trash, from what I’ve heard. I haven’t had one since long before google bought them.
