Nutrition is almost more important that the actual training or practicing for the big race or tournament. It involves careful calculation and planning at least 7 day prior to the big day. Carbohydrates are the fuel for your body. The big race or tournament burns a lot of carbs. The exact number of carbohydrates you burn per mile depends upon your fitness level, experience level, pace and running economy. For example most marathon runners average around 110 calories per mile with about 75% of those calories coming from carbohydrates. A typical runner can store approximately 1800 calories worth of carbohydrate in their muscles, liver and blood. That amount of carbohydrate will be depleted in about 22 to 23 miles which explains why most marathon runners “hit the wall” at that point in the race. Here is an example of a “Final Taper Week” which explains exercise duration and Carb intake leading up to the big race or tournament.
- Day 1 – Exercise Duration – 60 minutes, Carb intake – 60%
- Day 2 – Exercise Duration – 40 minutes, Carb intake – 50%
- Day 3 – Exercise Duration – 30 minutes, Carb intake – 40%
- Day 4 – Exercise Duration – 20 minutes, Carb intake – 70%
- Day 5 – Exercise Duration – Rest, Carb intake – 70%
- Day 6 – Exercise Duration – Rest, Carb intake – 70%
- Day 7 – Race Day / tournament
The Big Day
Your big day eating plan has two phases. Pre-race /game eating and fueling during your race/ tournament. Get up early on race/tournament morning and eat a light meal of low GI foods. Do not fast. You will need to “top off your tank” and replenish liver glycogen stores before your race/tournament. The addition of some fats along with some low GI foods will also help keep your blood glucose stable. An example would be two pieces of whole grain toast with butter and a banana. Avoid high GI foods on race morning because it can cause your blood glucose to fall and you will end up using a very high percentage of liver glucose for energy early in the race. If that happens you will pay the price and have not energy during the middle of the day.
During your race/tournament it is time to eat high GI foods. The high GI foods quickly release energy and give you a fast energy boost. Good high GI foods that are convenient foods on the run are energy bars, energy gels and sports drinks.
The balance of nutrition and training is the winning combination.
