For endurance athletes, a lactate test changes everything.

It shows you:

• Your true Zone 2 (not a guess from your watch)
• Your exact lactate threshold pace
• How efficient your aerobic engine really is
• Whether your training is actually working
• The right intensities to avoid overtraining
• Precise pacing for race day

This is how runners, marathoners, and triathletes train with intention, not assumptions.

If you asked for ONE lesson from 28 years of coaching, this would be it:

Train Zone 2 by heart rate.

Not power. Not pace. Heart rate.

Your heart rate tells you the truth about the stress your body is under.
High heart rate = high stress.
Lower heart rate = controlled, aerobic work.

Every pro rider still straps on a monitor. There’s a reason — they track stress, not ego.

Zone 2 makes up about 80% of your training. If you don’t dial this in, progress stalls. If you do, everything builds on top of it.

What is SST and FTP?
Steady State Threshold is where sustainable speed is built. Pair it with lactate-based zone tracking and suddenly every workout becomes targeted, efficient, and measurable. This is how smart training replaces guessing.
