My 4th MAFF Test at the track this evening hasn't demonstrated any improvement in my aerobic base over the last 6 weeks, which is disappointing. The only (slight) improvement has been in the drift in pace from Mile 1 to 5.
It could be due to the cold weather, particularly as my HR monitor was showing 173 during my warmup and was a bit erratic even after it settled down, during the first mile - but even if I discount the higher heart rate for this mile my average heartbeats per km would reduce to 623 - still well short of where
it should I want it to be.
It could be due to my recent diet changes (see previous post), although I did have a light meal 2 hours beforehand and did not notice an lack of energy during the session.
I'm not too worried yet as I have another month before commencing race specific training, so i'll give it another go in a few weeks.
