Hi Scott, thanks for the reply, very much appreciated as I was entering the lab test hoping to get a more precise readings of my thresholds and it seems that this might not be the case. However, below are the results from the test:

Pace (mim/km) – Heartrate (bpm) – Blood lactate (mMol)

7:30                                           128                                   1.10

6:40                                           135                                   0.90

6:00                                           145                                   1.20

5:27                                            151                                    1.20

5:00                                           163                                    2.00

4:37                                            169                                   2.80

4:17                                            173                                    5.00

4:00                                           182                                    7.10

3:52                                            184                                    9.80

 

Would you say that it is safe to assume that my LT1 more or less correlates to AeT? Because it this is not the case than lab testing is not so helpful in determining ones thresholds. Or is it? During the past few weeks I was training with heartrate zones adjusted and can confirm that a 3 hour hilly run @150 bpm average is more taxing that before running @135-138 BPM average. Afterwards I feel tired (not destroyed) but it would be hard to do it again the next day. And I can imagine what would happen after a few weeks. However, my breathing was still somewhat easy in terms that I could speak to myself in short sentences (something like in these video https://www.youtube.com/watch?v=1RqY5EYOM0k). It is not comfortable to speak would rather just breathe but if I need to I can speak/talk. So I’m guessing that I was/am still in aerobic zone.

Regarding AnT I will be doing an uphill run in duration of 45-60 min going as hard as I can for the duration as in the testing report there is a footnote that my LT2 (171 BPM) does NOT represent the intensity that I can sustain for 1 hour.

 

Thanks for you valuable feedback!

 

Best, Pete
