I guess I don't understand pack running in cross country either. Could you explain? Are the slower guys somehow able to run faster when the faster guys run slower? If so, is there some physiological basis for the phenomena, or is it just plain magic?
I think generally when people talk about pack running they don't mean that a team's 1-7 run side by side for the entire race. Take this example:
Your team's 6th runner usually finish within 20 seconds of your 3rd runner. However, your 4th finisher likes to take the race out hard, and dies over the last mile. The #3 runner catches him in the last 400m, say. Your 6th runner starts out very slow and picks it up throughout the race, only (nearly) catching up to runners 3-5 in the last 200m. I think you would agree that, based on the results of the race, these 4 runners have roughly the same level of fitness.
The result is ok, in that they all finish pretty close together. But now imagine a race where they stay together at the beginning of the race, running at a pace that is sustainable (not too fast or slow). The effect of having 4 of your guys running together is significant. For every guy that they pass, their team score drops substantially. All 4 guys know that the other 3 guys are there with them, and if one guy picks it up slightly, the others will go with him. This is not true in the first example, because none of the runners are spending much of the race running with their teammates. They might catch or pass them, but they aren't running the same pace together.
Now obviously one can't compare the effect of pack running vs. individual running in the same race conditions, but using the prior example of a race, the idea is that the net finish place of those 4 runners would be lower than if they ran individually.
Again, no one is saying that you should take the individual favorite and make him run with the #7 on the team who is 3 minutes slower, but if your runners are around the same fitness level, pack running can help them push each other without sacrificing any finish positions. Of course, if you hate your teammates or something then there probably isn't motivation to run with them during the race.
