Here's my basic plan in general terms.
Milage base more or less as presented for 8 weeks. As the weeks go by I'll opt for hillier and hillier terrain and my fartlek workout will become more oriented towards hills.
4 weeks of hill training. On the advice of Nobby, I'll go with strong running (maybe 3/4 effort) while concentrating on good form and a forceful push-off instead of all those power drills. This workout is twice a week, plus a medium-long run during the week and a long run on the weekend.
4 weeks of interval training. Probably twice a week, and the general type of workout would be 4-6 mile repeats. Again, a medium-long run during the week and a long run on the weekend. By the end of this period, I want my long run to have built up to 23-24 miles. I'll take these really slow if I have to in order to make the distance.
4 weeks of consolidation training. Long runs drop back to 20 miles and I'll make sure I negative-split these (all the way down to marathon pace over the last mile or two if I feel up to it). In the middle of each week I'll do a 20k run at marathon pace. The rest of the week's runs are recovery runs with strides at 5k pace or so.
2 week taper (and the last week of consolidation training is really the beginning of the taper for a total of 3 weeks). Nothing new here.
This is all an experiment as I've never done it this way before. I'll bookmark this thread and let everyone know how it comes out.
