(marathon training) long run

I got this email from McMillan running, and was wondering if anyone does any of these "types" of long runs. I'm currently at week 5 of Higdon's advanced plan, and think incorporating some of these into my long runs would help. thoughts?

Long and Steady: Lydiard's Tried-and-True Long Run
The tried and true long run for the last 50 years has been Arthur Lydiard's long, steady run. Lydiard found that by running for 2 to 3 hours at an easy, yet steady pace (preferably over a hilly route), the body and mind developed the endurance to withstand the race-specific workouts in the rest of a marathon training plan. Perform several of these long runs in your plan, particularly in the early stages of your training.


Long Run with Surges: Squires' Boston Beater
A unique aspect to legendary coach Bill Squires' marathon long runs is that they include surges. On nearly every other long run throughout your plan, he suggests you throw in "surges" every 10 minutes. These surges may last only 30 seconds or up to 10-12 minutes, and the pace varies based on the duration of the surge. Athletes find that surges help avoid boredom and provide a faster average pace across the long run.

Fast-Finish Long Run: Rosa's Way to the Winner's Circle
With his athletes winning every major marathon on the planet (multiple times in fact), it's no wonder that Gabriele Rosa's training is influential. A unique aspect of Rosa's plan is to finish the last few miles of the long run fast. "Fast" means pushing the pace for the last 4 to 8 miles, but also running the last 10 minutes as fast as possible. This "emptying the tank" long run is quickly becoming a staple in the marathon plans of elite and competitive distance runners like you. It's likely one of the most challenging long runs you will do, but the benefits are worth the effort.


Long Run at Marathon Race Pace: Pfitz's Advanced Marathon Long Run
Specificity is a crucial concept in marathoning. While the long run is the most specific in terms of duration, it's also important to practice your goal marathon race pace within the long run. Pete Pfitzinger advises a couple of long runs where you run 12 to 15 miles of your total long run at your goal marathon pace. An example would be a total long run of 20 miles with 12 miles in the middle at goal marathon pace. This type of long run is great for faster marathoners who typically run their long runs slower than their marathon pace. For slower marathoners who typically run at marathon race pace or faster for their normal long runs we suggest doing this type of run at your Steady State Pace.


Pace-Change Long Run: Variety in Pace Gets You Ready to Race
Athletes in championship marathons like the Olympics must practice changing their pace, because rarely are these events run at an even pace. Run like the Olympians by alternating a faster-than-marathon-pace mile with a slower-than-marathon-pace mile. For example, if your goal marathon pace is 8:00 per mile, then a pace change long run should include 20 total miles with 8 miles in the middle of the run alternating between 7:45 pace and 8:45 pace. As your marathon approaches, you may even be able to alternate between 7:45 pace and 8:15 pace. This is a very tough long run, but is great for marathoners who expect to need to "change gears" throughout the race due to tactics or terrain.
