It’ll be interesting to hear from Centro directly why he made the move. Some will say that he’ll be moving-up to the 5k the next few years but Salazar is a great 5k coach. Mo won five golds and a silver at Olympics/Worlds in the 5k. Galen ran some very fast 5ks. So did Jenkins and Kejelcha and Ritz and Rowbury. Centro ran 13:20 under Alberto.
We’ll likely get the BS PC answer “I was just looking to change things up at this point in my career.” And there is something to changing-up the training at this point.
At this point, Centro Jr probably knows how to train. Probably he can still talk to his dad. My guess is that the move has much to do with him wanting people to train and watch TV with, as he doesn't appear to be a loner.
