Soccer pre-season training

My son plays on a strong HS soccer team. They are hoping to win a state championship this year. As such the coach is highly motivated and and has warned them of how tough the pre-season training will be.

I am uncertain about # calories, how much protein, how much carbs, how to do post-workout nutrition between sessions and still eat lunch, etc.
From past experience it seems that the body doesn’t want to eat much mode just at the time when energy expenditures are maximized. And you can’t run your ass off with a full stomach.

Given that the first two weeks will consist of 2-a-days with lots of running, etc., what would you suggest for nutrition and nutrition timing during this physically and mentally stressful period?

I play rugby and had similar questions. Eat a good meal that sits well in the stomach about an hour or 80 mins before practice.

I consume 1 scoop of Surge per 1 hour of practice, but in 2 servings.

i.e.

3 hour practice = 1.5 scoops Surge after 1.5 hours, 1.5 scoops immediately after practice.

I also drink gatorade in a 50% diluted mixture. 45 mins - 1 hour after practice have another real food meal.

Oh yeah. LOTS of rest and sleep.

Ice massage legs after practice- optional.
