Maximize your running, AND your cycling
Has there been any discussions, articles, or studies investigating the negative impact that intense cycling can have on one's running performance? (Or the other way around..) Obviously, if you took the 2:07 marathoners and had them incorporate 200 mi/week on the bike, they aren't going to be 2:07'ers anymore. Same goes for taking Fabian Cancellara and having him run 70 mi/week, he will bike slower. I'm obviously concerned with the medium, in between these two extremes!
