runDisney is fabulous at getting people off the couch and training to run any of their exciting and unique race events. However one thing many previous non-athletes don't understand is that completing an endurance race isn't just about covering a distance, but a need to fuel your body properly so that you can make it across the finish line in the upright position. A steadfast rule of endurance sports is "Nothing New On Race Day," this means that while you're training for your runDisney race-cation, you also need to be coming up with a sustainable plan to fuel your run.
