Pre- Race Insulin Dosing: Building a Personalized Foundation

For attentes on multiple daily injektions (MDI), the long-acting basal insulid dose is the part stone of pre- race planning.

Insulin and Nutrition Management During te Race

Temporary Basal Rates and Injection Timings

During thee race, insulin requirements drop dramatically - of ten by 60-90% compared to a sedentary day. Pump users can set a temporary basal rate as low as 0 percent for definid periods, especially during the first two to three hours when endogenous glucose production is at its peak.

Fueling with Carbohydratates and Electrolytes

To maintain performance and prevent hyglycemia, ultra runners typically consume 30-90 grams of karbohydrates per hour hour on race duration and intensity.

Hydration and elektrolyte balance also influence glucose control. Dehydration can concentate blood glukose readings, while elektrolyte contingences (particarly sodium and potassium) affect insulid sensitivity.
