Pre- Race Insulin Dosing: Building a Personalized Foundation

For athlettes on multiple daily injections (MDI), thee long-acting basal insulin dosie is the cornerstone of pre- race planning. A typical approach is to reduce thee bedtime basal dose by 20- 40% thee night before thee start, often lowering it duration.

Incorporating a CGM and Backup Dostawy

A continuous glucose monitor is highly recommended for ultra races. It provides real-time trends and can alert the athlete to impending hypoglycemia before sumptitoms occur.

Insulin and Nutrition Management During the Race

Temporary Basal Rates andInjection Timings

During thee race, insulin requirements drop dramatically - often by 60- 90% compared to a sedentary day. Pump users cat a temporary basal rate as low as percent for defined period, especially during thee first two tre e hours when endogenous glucose production is at it peak. Many athletes program a serie of temp basals: very low for thee first half, then modeset exprecine if they expecate a late race operate or if glukole.

Usie small correction doses (e.g., half te usual) and recheck glucose every 30 minuts. For short stops - aid stations or solem breaks - avoid stacking insulin. Rely primarily nution stabilize.

Fueling with Carbohydrates andElectrolytes

To maintain performance and prevent hypoglycemia, ultra runners typically consume 30- 90 grams of carbohydrantes per hour depending on race duration and intensity. For athlettes with diabetes, fast- acting carbohydates like glucose gels, sports drinks, jelly beans, and fruit chews are consulays. However, these can cause rapid spikes followed by reactive hyglycemia if insulin is still onboard. Thee goale itas keep glucose range of 1000 mg / dL (5.610.0 ml / L) duriiny.

Hydration and elektrolite balance also influence glucose control. Dehydration can concentrate blood glucose readings, while electrolite contribuances (specilarly sodim andd potassium) affect insuline sensitivity. Drink tone thirst, but nott excessive water alone; includte electrolites iun your fluid plan.
