Subject: RE: LT Test and Zones does it sound about right?I assume you mean that your average over the last 20 minutes of the test was 186; so that's the LTHR that the test comes up with. What system are you using to calculate those zones? They look off to me. If I plug your LTHR (186 ) into Friel's formula, for example, I get: Z1: 123-157 Z2: 159-169 Z3: 170-177 Z4: 179-185 Z5a: 186-190 Z5b: 191-196 Z5c: 197-206 Based on these zones, it makes sense that Z1 feels super super easy. (However, with practice, you should be able to run or at least jog, within Z1. ) |
