Heart Rate Monitoring And Time Vs Distance

Question:
I am 40 years old and began running two months ago. I now run 6 days a week, averaging about 22 miles a week. I'm faster than I was when I started, but I'm still very slow. Anyway, I read John Parker's book on heart monitor training and want to start doing it. It makes some sense to me.

He warns that to stay under your 70% ceiling on your slow days, it will seem that you are going very, very slow. I tried it today for the first time and my fear was realized. I cannot even jog and keep my heart rate at the 70% level because I'm still a novice. Instead I'm walking at a very brisk 4.3mph on a tread mill. It's hard to walk that fast, but it's too slow to jog. Anyway, any faster and I break the ceiling. I'm not jazzed about this, but that is not my main concern or why I am writing.

Currently, on my hard days I can run 3 miles in about 29 minutes. That's pretty hard for me anyway. I did 3 miles this morning and kept it at 70% of max hr and it took a bit over 42 minutes. I'm looking at my training schedule and I'm thinking that I need to change it up. Tomorrow I'm scheduled to run 7 miles. Well, the long runs are supposed to be run at an easy pace (70%), so this would take me about 1 hour and 40 minutes.

Most programs will say run 7 miles, but it's really shorthand for wnting you to run for around 45 minutes. Obviously I'm an hour slower if I keep at 70%.

So here is my question (finally!), should I (for now) be concentrating on time instead of distance? I eventually want to run a marathon, and some of their long days may have you run 14 miles or whatever. Well, that would take 3:16 which violates what they say out of the other side of their mouth (never make any training run more than 1.5 hours).

OK, so I rambled alot. My apologies. I just wonder what my training shedule should look like now. 45 minutes runs daily (alternating easy/hard) and an 1.5 hour long run? Or just keep doing the miles, and waiting to get faster before I up mileage.

Answer:
You've said very little about what goals your training schedule is supposed to serve (or said very much about it). A training schedule is never an end in itself, it's a means. A typical duration for a long run is about 90-120 minutes, but on your milage, it may be a good idea to run a little shorter. It depends on what your training goals are.

The important thing is to train consistently. No need to blindly or rigidly follow a program. Just keep your milage consistent, and gradually build up as your fitness improves. Just focus on general fitness. Once you've built up some milage, you can start doing long runs (1.5-2hrs or so) on a regular basis, then you'll be ready to do a serious marathon training program.

When you start training for a marathon, you will have to train for distance, not just time. After all, the marathon is not any shorter for you than it is for the elites, even though you're slower.

But you don't want to do 3 hour runs on a weekly basis. Most of the marathon people start incorporating these longer runs in the last 16 weeks or so before a marathon, the rest of the time the long run is usually under 2 hrs.
