Recently, Sage Canaday called into question Cameron Hanes participation in running events by pointing out some of the products he has openly discussed using. The topic raises questions about what the best process is for maintaining clean sport. I discuss what I believe both of their broader points include, and potential options to minimize the divide.

Super shoes, extreme in race carb consumption, and doping was a big topic in the running news the past week.
