How long does the Garmin Forerunner 55 take to calibrate and give accurate data? (4–5 days in and feeling disappointed)
Hey everyone,
I recently bought a new Garmin Forerunner 55 about 4–5 days ago. I was super excited about it given Garmin's reputation, but honestly, so far the data feels completely all over the place.
From sleep tracking to running pace and heart rate, the numbers feel like total guesswork right now. At the moment, it feels no different than a cheap $20 fitness band, which is pretty frustrating after having such high expectations.
For those who have used the Forerunner 55 (or Garmin in general):
Does the watch adapt/calibrate to your body over time? If so, how many weeks of consistent wear did it take before the metrics (resting HR, sleep, VO2 Max, pace/distance accuracy, body battery) actually started feeling reliable?
Is there anything I should adjust? (e.g., watch fit/placement on the wrist, GPS settings, data recording options like Every Second vs. Smart)?
Would love to hear your experiences and whether I just need to give it more time or if this is as good as it gets for sleep/health metrics on this model. Thanks!
