I always think about the group of women who came out of high school with Alexa, that included Sarah Baxter(who people callled the best high school cross country runner ever) Mary Cain, and Elise Cranny. Baxter never had any college success. Cain went pro while in high school, and Alexa did right after. Cranny went to Stanford. Cain had some initial success with Salazar, but clearly that was not a good situation and eventually she was broken both physically and mentally. Alexa had some moments and continued to improve, but never significantly enough to be truly world class. Cranny had an up and down college career. She missed winning national titles in DMR and the 1500 by tiny margins, she had success in cross country but was never a champion or on a championship team. Cranny had various injuries and low points during her college career. She also completed an extremely challenging degree at Stanford(Bio chemical engineering or something like that I think) She went pro and continued to make significant improvements(with a couple setbacks) Until she's at the point where is the fastest american at 5K and 10K, and can run the 1500 under 4:00. I wouldn't argue that the collegiate system is great for developing middle distance runners, but I would argue that Cranny made the best decisions to have the best life. In college she always seemed to prioritize team first, and excelled being part of a team as a pro as well. The other three don't even race anymore, and Cranny is still crushing it. All the college racing didn't burn Cranny out, and neither did having to do real academic work. I suspect the big improvement came as a pro because she didn't have to study or go to class and could just focus on running and obviously the Bowerman team had ideal training partners and coaching.
