Gut fatigue management

For races lasting 6+ hours, gut absorption efficiency decreases over time. Plan to reduce carb intake by 10-15% after hour 6 and shift toward easily digestible sources like gels and simple sugars.

What to Expect at RISE Running Festival (COMING SOON)

RISE Running Festival (COMING SOON) is a Ultra 100K (62.1 mi) ultra 100k held in Coming Soon, TX, US. Based on 5 years of historical weather data, athletes can expect median race-day temperatures around 80°F.

Temperatures at RISE Running Festival (COMING SOON) typically range from 68°F to 89°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.

Ultra-distance racing demands a flexible nutrition strategy. Gut absorption efficiency declines over many hours, so plan for variety — alternating between gels, chews, real food, and liquids helps prevent flavor fatigue and GI rebellion. Many ultra runners find that what works at hour 3 is intolerable by hour 10. Build your plan with options, not rigid prescriptions.
