I mean recommendations aside for an average man your maintenance calories are aleady 2200+, considering you're 2 meters or whatever I assume it's atleast 2500 for you.
I don't count anymore but I generally eat at the very least 3000 when I'm doing some sort of cycling that day because otherwise I would just feel like absolute shit at work the day after by noon.
I think finbert is right and you've been running on fumes for a long time especially when doing multiple workouts in succession
