Estimating Lactate Threshold
While not many people have the ability to measure their actually lactate threshold, there are tests that provide estimates. One simple way to estimate your lactate threshold is to perform a 30-minute time trial at a high, sustained pace. This test is suited to experienced athletes and should not be attempted by anyone who is not in top shape. The goal of this test is to exercise for 30 minutes at the highest effort that can be sustained and monitor your heart rate throughout the test. Your average heart rate during the final 20 minutes should correspond to your LT.
