Lately, I've noticed my average heart rate has significantly dropped from previous rides. It's on a route that I normally ride 2-3 times per week. My perceived exertion is roughly the same, my times/splits are similar, and the temperature/climate is largely the same (if not warmer). When I look at my post ride data (usually on Strava or Garmin connect), my time/percentage in my 'threshold' zone has sharply decreased. I've even tried to push myself harder to get my HR up, but it seems to stay lower than previous. I've checked my HR strap, so mechanical issues don't seem to be the case.
What gives? Am I hitting a new fitness level? BTW- I'm late 20s in age for those who think that might be a cause.
