I was wondering what my resting heart rate really was the other day, I know it is best to test it in the morning, but I rarely remember to actually check. So what I did was to wear my heart rate monitor all night long. It turns out that my average resting heart rate for the 8 hours that I slept was 63bpm, which is pretty much where I want it to be.
As far as I know this would be a lot higher were I not on medication, and it's also really unfortunate that I didn't check it before I started running regularly. From now on I will do a night's sleep with my monitor on, once a month. That way I can keep track of changes.
