Hello again, Lars
Then it should be in place. The reason for your very rapid zone times was that for some reason you had put your marathon goal for 4 minutes instead of 4 hours. This meant that the plan tried to put some quick zone sometimes, although not faster than any of the world´s best. Therefore, sometimes at 2 something per km.
Now it is fixed and you can take a look at both zone-times and training days. Into if it requires further adjustments. There is, after all, not so long to do well with, so there are limits to how hard the plan can be laid.
