Protein is not efficient as fuel, its building block for repair/build muscle, not fuel
Converting protein into glucose to use for fuel (or worse, convert to fat store) costs energy too, our body will prefer to use carbs/glycogen as main fuel
You need fast high GI carbs preload to perform high intensity workout such as sprint at maximum efforts
And you still needs plenty carbs for repair/build muscle so lots of protein just probably not good idea
Getting enough protein takes care of my other macros for me. It's hard for me to eat >2g protein/kg bodyweight (vegan). Getting 200g+ of protein a day carries with it eating enough carbs, healthy fats, etc. So I mostly just focus on getting enough protein in.
Also, since max sprints are using our phosphate system, we're not burning very much glucose. Think about it: look at how many calories you burn in a sprint session. It's not much! Roadies need lots of carbs. Sprinters don't need very much.
