VLamax, LT1 and LT2 are central parameters for long-distance pacing.
For triathletes, lactate testing is valuable because it connects thresholds with carbohydrate use, a key limiter in long-distance racing.
In triathlon, lactate threshold helps determine how much bike and run intensity you can sustain while preserving fuel for later disciplines.
LT1 is the conservative long-distance anchor, especially for Ironman bike pacing and easy aerobic volume.
LT2 marks high sustainable intensity and is more relevant for shorter races and threshold sessions than for full-distance pacing.
LactateThreshold helps estimate bike and run pacing for Ironman, 70.3 and Olympic distance from measured values, not generic FTP percentages.
Very easy work and glycogen preservation.
Long-distance efficiency and 70.3 preparation.
Olympic-distance preparation and controlled tempo.
Sprint triathlon and shorter threshold blocks.
Short intervals for aerobic capacity.

Common in triathlon testing, fast and portable.
High-quality measurements for coaches and labs.
App-supported self-testing with low strip cost.
VLamax influences carbohydrate use. For Ironman athletes, a lower VLamax can help preserve glycogen for the run.
Ideally with separate bike and run step tests, because watts and pace need discipline-specific interpretation.
Yes. LT1, LT2 and VLamax give a better basis than generic FTP percentages.
Long aerobic work below LT1 and less frequent high-intensity sprint work can lower VLamax over time.
Two to three tests per year, ideally around major training phases, are usually enough.
