Thanks for sending in your test.  My thoughts are the following:

1) You need to do most of your aerobic base training between 110 and 130 to flatten out the lactate curve (lower lactate levels).

2) People with your training background will often have a very low AeT relative to MAF and can breathe comfortably much higher than AeT.

3) The drop in pace as distance increases is to be expected when your aerobic capacity is low.  That’s because you are relying too heavily on the anaerobic metabolic pathway.
