What to Expect at Golden Driller Marathon

Golden Driller Marathon is a Marathon (26.2 mi) marathon held in Tulsa, OK, US. Based on 5 years of historical weather data, athletes can expect median race-day temperatures around 72°F.

Temperatures at Golden Driller Marathon typically range from 58°F to 83°F. The upper end of that range crosses into moderate heat risk. While not extreme, sweat rates will be elevated and athletes who under-fuel on sodium or fluids may feel it in the later miles. A dialed-in hydration plan makes a real difference here. Humidity is also a factor here, with levels reaching 84% on warmer days. High humidity impairs sweat evaporation — your body's primary cooling mechanism — so perceived effort rises even when temperatures look manageable on paper.

Marathon fueling is about precision. Current sports science supports 60–90g of carbohydrates per hour for events over 2.5 hours, with experienced athletes pushing up to 120g/hr using glucose-fructose combinations. Start conservative in the first hour (around 70% of target) and build to full intake by hour two. Given the heat potential at this race, sodium intake of 600–1000mg per hour becomes critical to offset sweat losses.

We do our best to keep race details accurate and up to date, but things can change and occasionally we simply get something wrong.

How many calories do I need?
Rather than replacing all calories burned, focus on carbohydrate intake — the primary fuel for endurance performance. Target 30-50% of caloric expenditure through carbs. Our calculator computes the exact hourly targets based on your Marathon pace and body weight.
When should I start fueling?
