TL;DR: When TP gives summary HR numbers for a workout, is the MAX HR pulled from the data or from what I’ve set as my max HR?
A couple of days ago I went out to set a PR on an 8.5-mile loop that consists of a 3200ft climb over 4 miles, 3 miles steep down, then 1.5 miles gradual incline back to the car. For the most part my pacing worked out, although there was about a mile near the top when too much time in Z4 caught up with me and I had to hike fast rather than run, and in the last mile I didn’t have enough gas left to trim a final 1:38 to reach my target time. Nice fat PR, but I’ll have to go back another day to reach my target time. I learned a ton about my current fitness for this kind of event and what I need to focus on in my next training phases to perform better.
I noticed something curious in my HR data, though. (For context, I’m using a Suunto Ambit3 watch with a Wahoo chest strap. I’m 42, just coming off my transition weeks after self-coached mountaineering training using TfTNA and three weeks in the Andes.) After this run, TP suggested that I should update my AnT to 180 from 175. Ok, that’s all well and good, and makes sense given how much time I was able to supposedly spend in Z4 without my legs turning to jelly. However, as I looked at the summary HR data (Min 124 AVG 179 MAX 196) and the detailed analysis, I noticed that the HR graph actually includes spikes above 196–a lot of them. 196 is what I have set as my max HR in my account settings, but when I look at the graph, there are dozens of spikes above 200, up to 206. Is TP somehow smoothing those peaks in the summary number, or is it just not reporting anything over what I’ve listed as my Max HR? And assuming the chest strap data and those spikes are real, would one normally update Max HR in TP after seeing data like that?
