Hey Gordo,

Thanks for the immensely useful article. I did my first submax test at the start of my 3-hour easy bike ride. I saw the first uptick in lactate already at 160W (from 1.2 to 1.7mmol/L), and it continued rising until 200W. After the ramp, I had 2 hours left, which I completed with an average of 180W, taking lactate measurements every 30 minutes. All measurements came in around 1.2 mmol/L, which was not what I was expecting, considering the high lactate at similar wattages during the ramp. Why could that be, and what should I bear in mind for the next test I do? Perhaps a longer warm-up?

Best regards,

Oskar

Hi Gordo

Hope you are well

I am on week 3 of your Advanced Triathlon Base Training in Training Peaks, this includes the Progressive Bike Test session.I am not doing any lactate reading/testing in my training, is it still worth doing this test? If so, how do I workout my FTP/zones from the result?

Regards Neil

Thanks Gordo! Super useful as I'm just about to do combined lactate and decoupling run tests in the field (track actually!) on myself and 10 friends after doing treadmill ramp tests. Can you give an indication on what %maxHR most folks AeT HR sits at? Thanks again.
