!!

High heat risk

Race-day temperatures can reach 95°F. Expect 15-25% higher sweat rates. Increase sodium to 800-1200 mg/hr and plan for more frequent fluid intake. Pre-cool with ice and cold fluids.

!

High humidity conditions

Humidity averaging 72% combined with warm temperatures impairs sweat evaporation. Your body works harder to cool itself. Reduce intensity expectations and increase fluid intake.

What to Expect at Texas Triple

Texas Triple is a Marathon (26.2 mi) marathon held in Dallas, TX, US. Based on 5 years of historical weather data, athletes can expect median race-day temperatures around 83°F.

Temperatures at Texas Triple typically range from 76°F to 95°F. This puts the race squarely in high heat risk territory. Sweat rates can increase 15–25% in these conditions, meaning both fluid and sodium demands rise significantly. Athletes should plan for increased hydration, consider pre-cooling strategies, and expect pace adjustments — even well-trained runners slow 1–3% per 10°F above 60°F. Humidity is also a factor here, with levels reaching 88% 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 much water should I drink?
Fluid needs vary based on your sweat rate, body weight, and race-day temperature. A typical range is 400-800 mL per hour, but hotter conditions at Dallas, TX may require more. Our calculator provides personalized fluid targets adjusted for the expected weather.
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?
