Temperatures at Wasatch Front 100 2027 typically range from 66°F to 80°F. The upper end of that range crosses into moderate heat risk.

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.
