I've accumulated several marathon training plans (Daniels, Pfitzinger, Hansons, Sage Running BQ, and Runner's World Advanced) in anticipation of an upcoming spring marathon. I'm 35 with a family, work 50-60ish hours a week, and anticipate being able to get in roughly 70 miles per week. On limited occasion, I might be able to max out around 90 miles. I'm aiming for a very modest goal of 3:15. My lifetime 5k PR is 16:50 (college age). My current 5k time is 21:00 (my body/brain just doesn't seem to want to overtake this -- even though I'm currently running approximately 50 mile weeks).
Other considerations...I live in the Northeast with very harsh long/dark/cold winters. Most interval work would be done on a 160 M crowded indoor track.
Daniels (56-70 mi):
This is probably the most complicated of the plans, and probably the most taxing. My primary concern with this plan is how close to the brink of injury and over-training it might bring me.
Pfitzinger (55-70 mi):
This seems to be a popular resource on this forum. My primary concern with this plan is fitting the mid-week, mid-long runs (15ish miles) in on the mid-winter dark icy and snow covered roads. Might have to do a number of these runs on a treadmill.
Hansons:
The advanced plan is probably most tailored to average working class schmucks like me. The book addresses its recommended 16 mile long run in great detail. Obviously, that distance gets adjusted with the time you're out running. I guess my primary concern with this plan is that in my only marathon, my legs seized up between miles 21-25 and it ruined what would have otherwise been a decent race. I really haven't read many bad reviews from people who have executed this plan, so I might be leaning towards trying it. I also find their marathon simulator 26.2 KM run to be intriguing. Not sure I'd be getting enough distance in for Hansons to recommend attempting this workout, however.
Sage BQ Plan:
Like Hansons, this plan is also easy to follow, and seems to be tailored to working class schmucks. The primary difference between this plan and Hansons seems to be the recommended distance of the long runs (20-22 compared to a recommended 16). This plan is also probably closer to the top of my list.
Runner's World:
I used this plan for my only marathon attempt. It's easy to follow, and I did like the shorter and faster early workouts. They really were useful rust busters.
