Calculating HR Zones from Ramp Test


#1

I’m wondering how to calculate the lactate threshold hr from the ramp test.
Should I take the max HR and then take the % of it to find the LTHR. Alternatively, take the last 10-15 minutes average of the test to find the number?
This was easier on 20 min ftp test as it fits in the calculation guideline.
Thank you in advance

No idea unfortunately, but think this deserves a bump.

Hey there!

At TrainerRoad we are focused solely on Power, so we haven’t designed the Ramp Test to accommodate HR unfortunately. That being said, I would recommend checking out these threads to see what the community has to say on this subject:

My understanding is that HR @ FTP is within spitting distance of LTHR. It would definitely be a better estimate than using a percentage of max HR or trying to fumble some math through the ramp test. I’ve heard this equivalence a lot from the Coggan, Friel, etc, and while other people may be right on some details, I think for most people, it’s pretty accurate: https://www.joefrielsblog.com/2014/06/common-but-confusing-training-terms.html
