Not boffin but Mrs Boffin actually (I am sure he won't mind!)
I have been using a heart rate monitor for most of my runs over the last couple of weeks and I have been really horrified at how high my heart rate goes at the beginning of each run.
Even when I start out for a really, really slow run it leaps straight up to 180-205bpm. After about 2-3 minutes at that pace it slows down to a more sensible 140-150bpm for the rest of the run.
At first I thought it might have been the treadmill or the heart rate strap being a bit erratic but I have checked it on other equipment too.
I have been running for a couple of years and my resting HR is 60bpm so it is quite a dramatic leap!!
Is this normal?
Has anyone else experienced this?
