Is not free radical formation part of the supercompensation process.
Yes it is.

thanks for the link. Here are two important and very divergent factoids about free radicals in this article. (I'll cut and paste to make the points clearer.)
1. a transient, acute exercise-induced increase in free radicals is a positive and much needed metabolic event.
True, but now consider this....
2. It is well established that chronically elevated oxidative stress contributes to the pathophysiology of numerous diseases, including cancer, cardiovascular disease and diabetes.
Here is my premise AND my rationale for no longer training competitively for distance.
1. At younger ages, long hard runs produce transiently high free radicals that enhance the training effect.
HOWEVER...
2. At older ages, it takes much longer for elevated levels of free radicals (and cortisol) to return to normal. Thus, cortisol remains chronically elevated, which contributes to the pathophysiology of numerous diseases of aging... cancer, heart disease, COPD, diabetes, Graves disease, and more.
