Relentless Super marathon?

Humans are not the fastest mammals on the planet, but for very long distances (more than 40 kilometers) we can overtake any species living on land. Except some dogs.

The best runners on ultra-long distances it is a mark of husky and small-scale, which was brought out for races on sled. Carrying cargo they do not stop passing 5 marathons a day for a week or more (9 days = 1600 kilometers)

All thanks to an unusual way of turning food into energy.

The next is a small lecture on this: "in all mammals two types of fuels are used: glycogen (into which carbohydrates generate quite a lot of energy (at a short-term moment) into a brief last leap when energy is especially needed), fats and proteins burn not so well and are a long-term reserve of energy.

Glycogen supplies runners for brief especially fast distances, but tk it quickly ends runners for longer distances mostly rely on protein and fat. Only to burn fat and protein most mammals need to constantly burn a lot of glycogen, which is a problem, constantly the body can store very little glycogen and at the same time it is difficult to produce. By this runners run and get tired much faster than they could.

But driving dogs never fall without strength, because at the beginning of the arrival their body somehow turns into a state of burning fats without glycogen. Fats and proteins turn into energy almost instantly so dogs can resupply along the way. We don 't quite understand how it works, but after nine days and two thousand kilometers passed, most dogs come to the finish line with the same indicators.

Moreover, unlike people ultra departures after marathons who have to lay down for months, driving dogs (husky malamut) do not give almost any sign of fatigue. ( https://youtu.be/HDG4GSypcIE )

My question: How does this biochemical mechanism actually work to turn food into energy and can such a mechanism be created in my genetically modified people, so that they are not so tired when running and other physical activity?
