So do you think my leg endurance will be there for the 17.1 miles if I'm not running longer than 7 or 8 miles a day?
Well, you have to do a combination of long runs and more short runs in a week.
What I did for my marathon was two runs a week. One was short and one was long. I did about 5 weeks of training (which is not that long for a first time marathon)
I started at 15 miles a week and worked my way up to about 30 miles a week. Mind you the marathon is longer than your run. I think I ramped up too fast and that's why I had some calf problems.
Most marathon plans work to increase recovery (more runs a week) as well as leg endurance (longer runs at once)
Here is a sample to give you an idea. You can modify this one to fit your schedule and total distance.
I'm not an expert, but what I would do is alternate weeks
Do one week with 4 shorter runs to improve recovery
The next week cut it down to two runs that are long and equal to about 10% more than the previous week
Next week go back to 4 runs and increase the total milage.
Now, if you have more energy than that, I would suggest doing a day of plyo (bounding or jumping) a week. That will help your muscle power and make you faster.
Another thing you can try for one of your runs (in your 4 run week) is doing Yasso 800s - and example of a Yasso 800 would be: Want to run a 3:30 marathon? Then train to run a bunch of 800s in 3:30 each. Between the 800s, jog for the same number of minutes it took you to run your repeats. Add one repeat each week.
