Shawn Porter, Amir Khan, Alfredo Angulo and Bruno Escalante gathered in the Bay Area to train with legendary track coach Remi Korchemny recently.

At 81, Korchemny is sem-retired but teaches a handful of athletes as part of his ongoing work with SNAC System owner Victor Conte. Korchemny is an essential piece of the SNAC Boxing Team, refining the fighters' sprint technique and in the process, making them much more explosive in the ring.

For the fighters, the chance to learn from a master who cannot be hired but whose knowledge is priceless, is a rare and precious thing.
