Is max HR determined automatically by Garmin watches reliable? I've been [#running](https://fantastic.earth/tags/running) consistently for last one year (ran over 500km) and my [#Garmin](https://fantastic.earth/tags/Garmin) watch has been increasing my detected max heart rate slowly. Last week it reached 202 bpm, and that has me a little worried because I'm not exactly a young man (almost 40 now). Since my workouts are heart rate based, they have been getting harder too. Though I must say, I feel less tired than a year ago. Has anyone else experienced this? Is it safe to follow the max HR determined by the watch?

Six weeks ago I finished my couch-to-10k training, and ran my first 10k after a gap of 3.5 years. It went well, but the fatigue lasted for two weeks. Afterwards, I fell sick and couldn't start running for two more weeks. Finally last week, I started training again, for a faster 10k. And I realised that running couple of times a week actually makes me feel more rested and full of energy, as compared to a more sedentary life.

I have used Garmin 245 for years and it is completely worth the money. Plus they keep adding new features via software updates.
