Six weeks ago I did the 20 min FTP test from Coggan's book. So I took 95% of the average and came out with a number I'm too embarrassed to mention. Regardless...
For shits and grins, last week I did a one-hour TT and that average was exactly the same as what I had in the 20 min test.
Yesterday I did the 20 min FTP test again and game up with a number 20 watts higher than before. But I'm *pretty* sure I can't hold that wattage for a full hour.
Should I try the one-hour TT again to confirm the 20 min test result? Do I chalk up the improvement to my training working (i.e. higher FTP) or some sort of anomoly? Should I base my zones now on the new number? Somewhere inbetween?
Thoughts?
