Setting Heart Rate Zones (Running and Cycling)|
Step 1. Determine your lactate threshold heart rate (LTHR) with a short test.This LTHR test is best done early in the Base and Build periods.
To find your LTHR do a 30-minute time trial all by yourself (no training partners and not in a race). Again, it should be done as if it was a race for the entire 30 minutes. But at 10 minutes into the test click the lap button on your heart rate monitor. When done look to see what your average heart rate was for the last 20 minutes. That number is an approximation of your LTHR.
Note: I am frequently asked if you should go hard for the first 10 minutes. The answer is yes. Go hard for the entire 30 minutes. But be aware that most people doing this test go too hard the first few minutes and then gradually slow down for the remainder. That will give you inaccurate results. The more times you do this test the more accurate your LTHR is likely to become as you will learn to pace yourself better at the start.
Step 2. Establish your training zones. Use the following guide to establish each zone by sport.
Step 3. When following the heart rate-zone directions in my training plans or the workouts in the appendices of my books or my workouts in the menu of workouts at TrainingPeaks use the zones as established above.
