The toughest experiences of my sporting career, thus far, has been learning the hard lesson of not fueling properly for the marathon distance. I have payed the heavy price of not taking this as seriously as I could in the past. Have you been there? Does thing ring true in your own experiences?

Failing to hydrate and fuel properly is the absolute worst thing you can do, especially at the marathon distance. It is one thing to pass up fluid stations in a 5K. You can get away with that....
