Running Plan (11 weeks out!)

I've never been particularly good at organizing and following a set training plan, but as the marathon draws near I'm started to think that I should. As I mentioned in the previous post, I've been reading a book on marathon training which suggests the following training schedule for novice runners:

Week	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday	Sunday
1	rest	3 miles	3 miles	3 miles	rest	6 miles	cross
2	rest	3 miles	3 miles	3 miles	rest	7 miles	cross
3	rest	3 miles	4 miles	3 miles	rest	5 miles	cross
4	rest	3 miles	4 miles	3 miles	rest	9 miles	cross
5	rest	3 miles	5 miles	3 miles	rest	10 miles	cross
6	rest	3 miles	5 miles	3 miles	rest	7 miles	cross
7	rest	3 miles	6 miles	3 miles	rest	12 miles	cross
8	rest	3 miles	6 miles	3 miles	rest	13 miles	cross
9	rest	3 miles	7 miles	4 miles	rest	10 miles	cross
10	rest	3 miles	7 miles	4 miles	rest	15 miles	cross
11	rest	4 miles	8 miles	4 miles	rest	16 miles	cross
12	rest	4 miles	8 miles	5 miles	rest	12 miles	cross
13	rest	4 miles	9 miles	5 miles	rest	18 miles	cross
14	rest	5 miles	9 miles	5 miles	rest	14 miles	cross
15	rest	5 miles	10 miles	5 miles	rest	20 miles	cross
16	rest	5 miles	8 miles	4 miles	rest	12 miles	cross
17	rest	4 miles	6 miles	3 miles	rest	8 miles	cross
18	rest	3 miles	4 miles	2 miles	rest	rest	race

This week would correspond to week 8 on the schedule, which means I haven't done too bad. My actual schedule will be slightly different because I usually crossfit on Monday, Tuesday, Wednesday, Friday and Saturday. My plan moving forward is to sacrifice crossit on Saturday for a long run and I'd like to try and do yoga on Sundays (offered at my gym). As I typed up this schedule I noticed that it contradicts the notion that one can train for a marathon without going much over 30 miles in a week. I guess there isn't much one can do when the long runs start to approach 20 miles.
