Fuel early
Long trail runs need calories before the athlete feels desperate
- Climbs and rough terrain quietly raise total cost.
- Early small feeds are easier than trying to catch up late.
Carry smart
Pack fluids, sodium, and real backup food
- Vest or pack setup matters because aid is often far away.
- Bars, chews, trail mix, PB bites, and electrolytes all have a role.
Match the terrain
Hills and altitude usually mean higher carb and fluid demand
- Long climbs make the effort costlier than the watch distance suggests.
- Altitude and dry air push hydration needs higher too.

May start very early (4-5am) so dinner matters
Carry breakfast to trailhead if early start
