What to eat before an ULTRA? - The previous weeks' diet

The diet in preparation for an ULTRA will enter a critical phase in the last two weeks before the race. This period must be negotiated carefully and must provide the body with the fundamental elements needed to be ready for the event. If you don't know what to eat before your ULTRA, follow the guide, our advice is here!

Nutrition in the last two weeks before the UTMB®

As indicated on the nutrition pages of the UTMB® website, the meals of the last week must anticipate the future energy needs of the event. Their aim will be to maintain the metabolism at a high level. To do this, you should plan three to four meals a day, without excess and without nibbling during the day. The overall ration for the day should be 2,400 to 3,500 kcal depending on the profile, with 20 to 25% fat, 15% protein and 60% carbohydrates. It is important to maintain a good level of hydration with a quantity of 1.5 to 2 litres per day. 

The last few days

At D-3 it will be important to switch to a high-carbohydrate diet for endurance athletes. This will consist of 65 to 70% of carbohydrates each day with a preponderant share of complex carbohydrates at all meals, including of course starchy foods and bread. The aim is to practically double muscle glycogen stocks: to do this, eat two large plates of starchy foods per day, bread at every meal and, if possible, cereals in the morning.
