Lactate Threshold Testing

Based on a series of blood draws during a step test, an SoS coach can accurately track your body’s physiologic response to training and pinpoint your lactate threshold.


With these numbers, we can then develop power ranges and heart rate ranges for cyclists, as well as pace and heart rate ranges for any runner. This test assists our team in developing a more precise training schedule for each athlete.

It takes roughly 1.5 hours* to complete and analyze the data that is accumulated from the test. The test consists of a step test (administered on a cycle ergometer or treadmill) and a series of small blood samples during different stages of the test. We use the smallest gauge lancets possible for our blood draws to decrease the invasiveness of the testing. Each test uses a small (2mm sized) drop of blood.

*if paired with a VO2max test, time to completion is roughly 2.5-3 hour.

Lactate is a marker of the accumulation of waste byproducts created during exercise. It is important to understand your threshold because it is one of the most important physiological markers we can utilized in your training. At Science of Speed, we use the highest quality equipment to scientifically and accurately calculate your lactate threshold.
