General rule of thumb is you can process about 300 calories an hour. So with a reasonable amount of Cytomax you'd be on that target.
Of course it depends on length and intensity of the ride. 100 mile plus race in the mountains, you need to eat like that early, or you'll pay late.
30 mile training ride, you eat like that, you are likely to gain weight.
