Deciding to run a triathlon, whether it's the sprint version or a full-fledged Ironman, is a major commitment. Preparing for the event means long hours of running, swimming and biking, plus additional strength and core training. Triathletes also need to practice transitioning smoothly from one leg of the race to another -- something that's a lot harder than you'd think.
But perhaps the most crucial element of any triathlon training regimen is your nutrition plan. Making sure your body gets the right combination of carbohydrates, protein, vitamins and hydration can mean the difference between a successful race and a painful ordeal. This combination isn't going to be the same for every person; all of our bodies burn energy at different rates in slightly different ways. Accordingly, one of the most important parts of your training will be to discern how much fuel your body will need, and when it will need it.
