Hi I am a lurker but not much of a poster but I am looking for some heart rate advice. I finished my 25min 6 run 3 yesterday and I thought it went well. I use runtastic and have just purchased their Bluetooth heart rate monitor which is working great, but when I checked my run after I spent 48% of the time in the fat burning 133+ zone but an alarming 24% in the redline 163+ zone. Is this dangerous or am I really that unfit that although I feel fine my poor heart is overexerting itself? Until I looked at this information I was feeling quite pleased with myself as I had not run for that long since last June before I tore the ligaments in my ankle and finally feel like I can Run again 😃
Thanks for any advise you have..... looking forward to completing this and finally getting 5km under my belt again ......
