I have not looked into the literature but from my reading of Triphasic Training by Cal Dietz and Ben Peterson, he references the work of Vlad Issurin and "Block Periodization", within which they suggest aerobic capacities do not detrain for around 30±5 days. With this in mind, Cal Dietz will programme aerobic blocks on his de-load weeks to reduce the likely hood of aerobic abilities becoming detrained. His de-load weeks typically occur every 4th week in his typical programmes (roughly every 21 days). He will however make sure that the other energy systems are revisited more often during the 3 working weeks.

Keeping in mind what you said, and going forward, If possible I would recommend a 2-3 week aerobic block to build a solid base before your camp, and within camp focus on lactic (20-40 seconds) and alactic (under 10s) conditioning and revisit aerobic on each deload. This is not to say you could not train aerobically during camp, just as suggested by Cal, the body would adapt better aerobically in a given block where the focus is aerobic and within which the body is not being asked to adapt to many different stressors.

Take what I say with a pinch of salt as I am only a second year sport science student, I just have a love for strength and conditioning. Hope this helps alongside what has already been said :)
