Time for some truth.
First, I know the former boys, now men, who supposedly ran 100miles per week in high school. And they did…Once. They collectively had a goal of running 1000 miles over the 12 week summer leading into cross country. That is 83 miles per week, on average (because of math). The final week of the summer, they approached 100 miles (again, once). They were upperclassmen, physically matured, and were aligned in their mission. They typically averaged 65-80 miles per week throughout the remainder of their seasons, which is pretty standard for elite level high school runners (both 20 years ago, and now).
Since that time, Bill Aris’s training methods have evolved with the times as has been clearly indicated by some posts within this thread from parents in his program now. So he seems to have learned that the older way of doing it isn't as accepted as it once was. Commendable, intelligent, adaptive.
Unfortunately, the recent results prove that, because 40-55 miles per week as parents are reporting won’t even win you a sectional championship these days. At some point, parents might even decide that winning a sectional, state, regional, or national championship is desirable. And when they do, they, too, must accept the risk of injury that comes with training for such lofty endeavors.
Regarding your sacrificial lamb story (whom I also know and who remains family friends with Coach Aris to this day!!) - that absolutely happened! What is missing from your context is a lot. This runner expressed interest in improving on hills during races and had been working toward that goal in her training prior to the Federation Championship at Bowdoin Park (where NXR - NY/NE is still held today). With her improved hill strength leading into the meet, Coach Aris tasked her with being the so called “sacrificial lamb”, inspiring her to lead her team to the top of the hill, mid race. What a confidence boost this was for her. The best part, untold in your version, is that she continued on with her excellent starting position, and carried it through to the finish! She finished in her highest team placement of the season through that point. So his strategy not only benefitted the team, but also the individual. It worked. That is just one example of the magic of Coach Bill Aris. A negative story, turned 180 degrees to positive. With the simple, good, old fashioned truth.
Last point. For a coach to be viewed as overstepping, or what have you, for encouraging his top nationally ranked team to wear hats to preserve health and wellness in the days prior to the national championship, in a climate 3000 miles away from home, is laughable.
If these truths hurt your feelings, that is unfortunate. But it doesn't change the fact that they are true.
