Hey guys ,
I have one question for you .
Anyone here own a Garmin FR 235k ? I know that the built-in optical sensor HR is unlikely to be achieve results compared with chest belt ​​, but I want to ask if someone had problem with it and with measuring HR, and how you guys have dealt with it somehow ? for example, by placing watches higher on hand ( by moving above the forearm or so ) or otherwise ? .... I'll be happy to receive any opinion and advice.
Just for info, I ask because I have an watches for about two days ... Yesterday measuring HR seemed fine - I ran about 16 km, pace + - 4:58 min / km and average heart rate was 151. Today we ran 10 km ( small mountain ), the pace was 5:48 min / km and I had a heartbeat still around 85 - 92. I do not know whether they are corresponding values ​​..... So far I've never had these kind of gps watch .
Thanks for any advice or response.
