I've a garmin forerunner 410 with a hr monitor but I've been getting some very high heart rates that I don't think can be right.
Here's a few examples
4.42km run in 17:45 min. Avg hr 168, max hr 186. Lowest heart rates I've got even though the run was at a fast enough pace.
4.4km run in 18:47 min. Avg hr 171, max hr 201.
4.4km run in 18:50 min. Avg hr 203, max hr 237. An easy run but the hr goes through the roof
4.42km run in 17:27 min. Avg hr 201, max hr 235. Fast enough run but my heart didn't feel like it was going to explode and I didn't feel like I needed to stop.
8.1km run today in 36:02. Avg hr 194, max hr 219. A slow run and not even tired after but hr still very high .
Is my hr monitor just very inaccurate and is there any point wearing it if it keeps showing these crazy heart rates
