I measured my zones in a lab about 3 years ago. Can I still take those as valid, I mean +/- a few beats?
I’ve been off training for a while due to a hamstring injury, which obviously has set back my pace values a lot, so my endurance is not worse because I have been lazy.
But can I take the lab measured zones as more or less valid I know my HR-T is about 180 bpm. Yesterday I ran a half where i was 1 hour > 189 bpm, so the algorithm wants to increase my threshold. But I think this can be disregarded because of race environment?
I know there’s been studies that show HR at LT1 and LT2 don’t really move during a season (ie after a break / pre season / racing / post season), so you’re probably pretty safe to use the HR numbers you’ve got now.
Sounds like you’re very ‘fresh’, so will see some ultra high HR numbers to start with.
One first question: before your injury, did your HR threshold correspond well with what you perceived during your races?
I agree. You should keep this in mind, especially if your training volume is currently extremely low and inconsistent. For someone who is already trained, it is very difficult to see such a drastic change in HR threshold not only within a season, but even across a span of a few years.
Of course, this depends on both the starting point and the current situation in terms of training history, overall load, age, and other factors (such as chronic medication use, major body composition changes, etc).
Yes, my race-HR for half and 10k has usually been around 185 bpm, even if my speeds were obviously much better. But it depends, usually the better prepared I am, the lower I can hold my HR, usually a high HR is when I’m trying to run faster than I am fit (like this time, I was going to skip the race but then I just went for fun ex-tempore).
Here are some examples, can you see these races or do I have to change some setting? Intervals.icu Same race in 2022, avg HR was 191 Intervals.icu Same race in 2024, avg HR was 183 Intervals.icu HM in 2024, my PB, avg HR was 178
My CTL is now about 30, it was 55 when I was in good shape. But the majority of TSS now comes from cycling, whereas when I was in training shape I did two intervals a week, so I guess it’s called junk-km.
