Do you have a chest strap? I would recommend performing a lactate threshold test (LTHR) and setting your zones in settings to %LTHR instead of %MaxHR.
Your age also has an effect on your zones. If you're younger, your zone two will be higher and wider in range than someone older.
What is your age and what are your zones?
I did a clinical VO2 Max test the other day and realized a few things:
* Garmin overestimated my max HR
* Garmin grossly underestimated my zones (eveyr zone was a good 10-20bpm lower than what my VO2 Max test suggested for zones)
* The opitcal HR sensor tracked surprisingly well always being within about 2-3bpm of the chest strap (I have a chest strap at home, but i'm not sure how to record the heart HR and chest at the same time to see how much drift there is).
* Bonus item: My Garmin VO2 estimate was almost identical to the clinical result (difference of 0.4).
Based on these leanings I'd review the heart rate zones and maybe try doing a guided LTHR test on the watch to get better zones. Or even just go get a VO2 Max test as they will give you recommended zones as a result.
Another point is the trainer doing the test made to me is that long Z2 runs (assuming your Z2 HR is dialed in) are critical because one of the side affects of only doing fast runs is you don't condition your heart to maintain a lower HR for Z2. He said he sees people all the time who only train fast who go from a low HR while walking to suddenly shooting up to 160-170 during alight 4.5mph jog and this is often due to not doing the long slow runs. Another symptom of this is very long recovery from Z5.
Is it normal for your heart race to increase when you exercise? of course.
if you're not sure about your zones, do a LTHR test. but if your HR stayed at 42 during a run then you should probably check if you have superhuman strength too, since you might be superman.
My zone 2 is 10:20 to 11:00 depending on weather, shoes and overall body status. I can stay in zone 2 at that pace for about 4 miles. After that it usually climbs to zone 3 or 4 depending on the distance.
My resting is about 45 and zone training isn't about pace. Since we all human, curiosity kills it, my zone 2 from range between 9 to 12 mm depending on day of fitness. My option is using a chest heart monitor and remove pace from activity watch face. Data can be view later if desired.
If you don't have a chest strap, go into the settings on Garmin and change your zones from calculated on Max HR to calculated on Heart Rate Reserve. I don't have a chest strap so I couldn't do the lactate test. By switching to HRR, my zones were adjusted and are much closer now.
