How long was your test before the malfunction?

My drift test was going fine when the heart rate suddenly disappeared from my watch towards the end and reappeared with an erratic reading. I don’t know why this happened, but my HRM unclipped and loosened twice during the jog. Pa Hr was 3.47% for the first 40 mins before the HR disappeared.
Will I have to do the test again?
So I did the test and would like to confirm my result. I was on a stair stepper at my gym and using the analyzer I don’t see the Pa:HR percentage anywhere, just an IF. I read that is because there was no GPS data because I was inside, right? So if I take first and second half and get (155-150)/150 * 100 or 3.33% does that seem right? Thanks!
@Andrew – that sounds like the right way to do it to me. If I recall, we only get Pa:HR if there’s GPS data as you noted.
@Saadia – I have the same issue with my HR monitor and watch. Very frustrating sometimes as it’s unpredictable. Doesn’t happen often enough to warrant new gear, but just enough to frustrate me once a month or so. Was hoping it wouldn’t happen during the test.
Question for the group – assuming my % drift is good, is the top of my Zone 2 going to be:
(a) the number I was aiming for during the test? or
(b) the average HR of the first half of the test?
I failed my drift test. 53-year-old, so formula suggests 127, which felt too easy. After 20 min warm-up, I started test at 137, thinking I would drift to ~143. HR fell on average to 134 first half and 135 second half.
Any guidance on a better target starting point? (For context, my Garmin Epix set my zone 2 top at 136 out of the box.)
Before doing a test or a training , it is always important to check the conditions of the heart rate strap , sensor .
Problems with the strap :
Loosing of points of contact of with a loosen heart rate strap or a bad attachment of the sensor to it can cause bad readings and a failed test or training .
Problems with the sensor :
most common is that the sensor runs out of battery or is too low , when that happens the sensor tends to give bad readings such as :
– starts blocked in higher or lower heart rate and then start reading normal after a while
– the readings go high or low without a change of pace/ rhythm
– the sensor starts giving readings that don’t correspond to the perceived exertion (rep)
Always check your gear on the day before or with enough time for you to be able to solve the problem and still do your activity
Adapt and do it by feel, when in a training even if your gear does not work .
