I need help setting up a schedule to follow in preparation for Boston. I've broken it down into an 18 week calendar...starting just after XC Club Nationals in early December. I am currently on week 8 and have averaged 70 mile weeks for the past 7 weeks (that includes two 50+ mile "junk" weeks I did when I went skiing). I feel fairly comfortable at 75 mpw and plan to "up it" soon with doubles.
My typical week - 10 miles every weekday morning (sometimes 9), 10 on Saturday and 15-20 on Sunday = 75mpw. My simple plan is to start increasing some of my morning 10s to 12 and then start doubling up and adding mileage that way. I'd like to peak at 100 or just over and would like to plateau btwn 95-100.
My big question is how many weeks should I try and hold this plateau and how far back from "Marathon Monday" should this be? I feel very strong and feel like I will be very ready. The long runs feel quite easy compared with those I did last year.
FYI - week 18 is the week (M - Su) before the marathon. Week 19 would start on race day.
Thanks for any assistance you can provide.
