I took up c25k (again!) and started at week 3 after a couple of months of doing nothing much. After completing my first 3 minute run, I was aware of having fluttering palpitations which lasted about a minute. I've had palpitations at rest before (they've been investigated and seem to be benign) I think they are generally caused by caffeine and/or anxiety.
My question is, did these palpitations perhaps happen because I over-exerted myself (well, hardly, I'm the slowest runner in the world and I'm not exactly fit!) and if I cut back to week 1/2 would this be okay? Has this happened to anyone else?
I should also say that I did the second 3 min run in the same session and felt ok.
