Her ideаl spоrt drink's cаrbоhydrаte cоncentration would be Case Study: Sally was an amazing, hard-working runner. She is 105 lb, age 25 years, the typical training temperature is 70°F, and her practice time for the 10K is 50 minutes. She successfully ran 5Ks for her university but was trying to run longer distances to try to compete for a spot on her country’s 10K or marathon Olympic roster. She started training longer distances and found that her 10K time was getting gradually better. Sally entered her first 10K race and, to everyone’s amazement, came in the top three. With that success, she decided to work toward going the 26.2 miles for the marathon. Her country was not known for producing top-notch marathoners, and Sally saw this as an excellent opportunity to make a name for herself. To prepare, Sally followed her proven formula for the 5K (3.1 miles) and 10K (6.2 miles) by gradually increasing her practice mileage in her morning run and her late afternoon run. To her surprise, she started “hitting the wall” after 10K, but figured if she persisted, she could eventually pass that barrier and go the distance. To her dismay, it did not happen. She just could not get her body to go past 10K without stopping, and she knew that stopping was a terrible way to win a race. During her 10 K training, she also realized her urine color was dark and experienced muscle cramps for several times under high temperature trainings. She decided to call a retired marathoner to see if she could get some ideas for how to do better, and the marathoner asked her to write down her training protocol: “Sleep, Wake-up, Glass of Orange Juice, Morning Practice Run, Shower, Dress, Breakfast . . ..” The marathoner realized right away what was happening, and asked the key question: “What do you drink during your morning run?” The answer was “Nothing . . . I never drink anything during my practice runs.” The response was immediate: “You are trying to emulate your 5K training, but you are increasing the distance dramatically. You are running out of fuel and fluid, making it difficult to sustain normal blood sugar, normal blood volume, and the normal sweat rate, making it difficult to adequately cool yourself. Try drinking a suitable fluid in the same pattern that you are able to drink during the Olympic marathon . . . every 5 kilometers.” To estimate her sweat loss, she measured the average drink volume for her 10K practice, which was around 200ml. She lost 2kg (4.4lbs) from beginning to end of her training. During her 10K training period, her total urine volume was 200ml. After this, Sally figured out how to put some beverages on the trunk of her car, run 2.5 km out and 2.5 km back, grab a drink, and repeat this pattern. Almost immediately the carbohydrate, electrolytes, and water in the beverage started helping and Sally was soon able to go the distance. She learned something critically important. It takes more than a desire to compete — You also have to do the right things.
