Probably just a lot of factors such as sleep and nutrition, especially in our 30s when we can't live on a diet of Snickers and Doritos anymore
Definitely try to keep it up. You will get injured less often and so be able to run more and should enjoy it more too. Don't feel bad slowing down, or even walking up hills if you need to. Make sure you still do some speed work every now and then though. Even if it's just some strides at the end of a run.Sounds like everyone is doing well at the moment, keep it up! Just done a run having had alerts set for HR going above 150bpm, not sure how I felt about it as it just felt a bit odd slowing down even more whenever I got an alert lol. Ended as an average of 150bpm bang on with an average pace of 10:48/mile, should I carry on running this way for the time being then?
