This gluten-free, dairy-free, vegan option aligns with many runners’ dietary preferences and supports steady energy without artificial preservatives or flavors.

This option is valuable for athletes who need an extra edge during late-stage ultras or hot-weather miles.

While not a nutrition product, footwear comfort and energy return influence performance during ultra events. MOVE Baseline insoles provide neutral support with lightweight, energy-returning foam to help reduce fatigue and support prolonged activity. For many runners, comfort and stability can affect pace and miles won or lost over ultramarathons.

Buying Guide: Key Purchase Considerations For Ultra Running Nutrition

  • Fuel type and sourcing: Real-food gels like Huma emphasize recognizable ingredients and fewer additives. Consider your tolerance to new foods during races and test during training.
  • Carbohydrate mix and absorption: Gels using dual carbohydrate pathways (maltodextrin and fructose) can provide smoother energy delivery and reduce gut distress during long runs.
  • Electrolytes and hydration: Pair gels with fluids or hydration packs that supply electrolytes to prevent cramping and maintain hydration status, especially in heat or high-mileage events.
  • Digestive comfort: Choose products formulated to minimize GI issues. Gluten-free and dairy-free options may suit sensitive stomachs while maintaining nutrition quality.
  • Portability and accessibility: Bulk packs save money and ensure steady access to energy sources. Hydration gear should be lightweight, secure, and easy to drink from on the move.
  • Gear integration: Hydration vests and collapsible bottles should complement your fueling plan without adding excessive weight or bulk.
  • Testing and consistency: Test gels, hydration strategies, and gear during long training runs to refine your race-day plan and avoid surprises.
  • Regulatory and safety considerations: Ensure your gear adheres to event rules (e.g., permitted hydration systems) and carries necessary emergency info and electrolytes.
