Energy vs Biology in an elf-human hybrid

This character is an elf-human hybrid, who can travel long distances at high speeds with little rest. She can run at top speed (what we call sprinting) without stopping to rest, sleep or eat for three days. It is generally accepted that elves are very hardy and fast, case in point: Legolas from Lord of the Rings or Arya from the Inheritance cycle.

My question: How would an elf or an elf-human hybrid gain the energy he/she needs to run such long distances, at such high speeds, without rest, sleep, or food? The energy needed must come from somewhere, but the concept of an elf needing to gorge on mountains of food to keep up his strength seems a bit vulgar. On the other hand, elves don't have slow metabolisms: I've never heard of a fat elf...
