TSS, Training Stress Score, zones

★★★Table Estimating TSS from RPE, Heart Rate, Power or Pace

General zones comparison

Tristar Athlete, use the following table to help combine various energy systems used in measuring training output.  NOTE: While the table lines up nicely with each respective measurement type, it is rare that they track this directly and hence why there are different ways of measuring.  The best approach is to stick to what the workout is calling for and if for example you don't have a tool (heart rate monitor, or for example power-meter. You have the ability to use an alternate tracking method).

Example of fitness differences: There are times when "unfit" you may be at power zone 2 and threshold heart rate!  Or similarly when very fit you are at threshold power but heart rate zone 2!!. (This also holds true for pace and heart rate targets on the run.  Your coach will help create a plan that develops your strengths and weaknesses based on your experience level and periods of peak training.  We use ALL of these methods at various times to get the best training and peak fitness possible.   

How do zones compare based on your ability?!

These charts demonstrate that perceived efforts based on your ability will produce different outputs. Example; beginner Atheltes will find an effort “easier” even though their heart rate is higher due to their lack of base aerobic fitness when compared to a more advanced athlete. See how you compare.
