Lactate threshold in Suunto Run
-
Hi,
In the Suunto Run the CTL widget shows me a very different lactate threshold (152bpm) than ZoneSense does (166 bpm).
Which one should I use to set my HR training zones?

@Pep-Carbonell only accurate method is a professional lactate measurement on a treadmill.
If you can not do that or you don’t want to spend the money, a field test like a 10km Time-Trial/Race or 1h all-out is the most accurate you can go.
The average HR for the last 20 min is in the ball park of ±3 BPM of your lactate threshold. If you do that 2 or 3 times over the next months to reduce daily influences you will be able to quite accurately narrow down your HR at the lactate threshold.Formulas like 90% of HRmax are way to inaccurate and can be ±20 BPM off. ZoneSense is already more accurate but can still have around ±10 BPM inaccuracy as scientific works could show.
A deviation of 10 BPMs is quite good compared to the other calculation methods but it’s still huge if you want to train correctly in the zones.
