  • Pre- race snack (30- 60 min before): 30- 50 grams of simple cars, such as a banana or an energy gel.
  • During race: aim for 60- 90 grams per hour, adjusting for heet, altitude, and gut tolerance.
  • Post- race: konsume 1,0- 1,2 grams of carbohydrate per kilogram of body weight with in 30 minutes, then every two hour for thee next 4- 6 hours to replenish cogygen stores.
