My experience in endurance sports is with cycling, and I have a friend that used a "ketosis" diet to help lose some weight. My understanding of the fat burning process is that it can only happen so fast, so with fat as your fuel source you are only able to support moderate intensity levels. This could explain the 7h 45 min minute time for his 50km run (~31 miles). I know if I am riding at race pace for a couple of hours and don't give myself fuel then I am in trouble, but riding at lower intensities I can go for a much longer time without eating as long as I have water. |
