If you are using the 80/20 zones and training plans I would recommend doing the talk test during a foundation run to get that result so that you are not mixing different systems and results. It may come out a wash – but the talk test is not overly taxing, and then you will have a result you can rely on with our calculators, training peaks zones and our structured workouts.
The result from the talk test and from the MAF-formula are nearly equal. But, fair enough, it is better not to mix different systems. I will stay with the result from the talk test and probably give it a second try in order to finetune it even further.
Yeah sure, I would rather go with the fun part right away, but thought it would probably be best to do an effort to set-up things right, directly from the beginning, so that I can forget about it for some time, while being sure to be going in the right direction.
