For the benefits of the other Forum members, unlike our other strength plans, the Core plans don’t pair with a particular distance or level, they are just straight duration-based plans in durations of 9,12, 15, weeks etc.
Charles, to answer your direct question, cut core sessions the week of your race.
A quick comment; the Core plan does overlay nicely with the 1/2 Marathon Plan so hard days are hard and easy days easy. Only those last couple of days leading up to race day seemed to be odd.
A shout out to Leyla – I did have a concern that the endurance & depletion days do overlap with the Core Plan which for me raise a concern because of my age and risk for injury. Leyla offered great guidance on how I might organize those days to mitigate the risks and I have integrated her suggestions into my Training Peaks Calendar.
My initial experience with the subscription services have been exciting. The ability to customize the plans to my needs, and the support I have received prepared me to enter into the next training segment with confidence that I have a workable plan that I can complete successfully.
