Competing in a triathlon, running a marathon, or just trying to beat your personal best time are all exhilarating, until you hit a wall mid-stride. Almost all athletes have experienced this, when their bodies run out of energy, not wanting to go a step farther, let alone faster. Thankfully, help is on the way!

Benjaman Rapoport has come up with an online calculator to figure out how many extra carbs athletes need to avoid the dip in energy that causes them to hit the wall. By entering into the calculator your resting heart rate and target marathon time you get the optimal number of carbohydrate calories needed to give you enough energy to get through your race.

Rapoport, a Harvard-MIT student and marathoner, gives athletes a great tool to improve their performance on game days.

Remember to carb up correctly before your next Spartan Race!

See you at the finish line!
