Scotty, I don’t have any concerns with this plan. It provides sufficient recovery, a reasonable period of training before the marathon, and a correct taper. The timing between the two events is not ideal, but it’s enough, particularly coming from a 50K to a Marathon.
No objections to the half, but it would indeed be best if done before Week 10.
The online run plans are indeed different from the book plans. We constantly update our online plans. However, your book plan is fantastic.
