thank you! Yes! Its good to hear you confirm what I’ve been feeling but hard to explain to people. My zones are so compact that its very difficult to execute workouts outside with wind/road conditions – any minor blip and I easy move from Zone 2 to Zone 4 or even zone 5 watts. For reference. I’m female, 40, 5’5, 120-123 lbs. My HR also seems to be lower than other people that I know. Resting has been about 45 average but my max HR on the bike is only 163. (run gets up to about 170). Those zones are so narrow that I have the same issue as the watts. With IM 70.3 WI getting closer – my plan just switched to race specific…so I don’t see another Zone 4 workout now.
For additional information I did CCI14 today for 1h30 min and it was quite challenging workout with 4 x 7 min Zone 3 being 155 watts.
