that’s a lot of weight gain, but you’ll retain a lot of weight from so many carbs.
Carbs are KEY to cycling success, and you do need your muscle stores filled with glycogen, but even as carb crazy as I want to be, the math from carb loading doesn’t always make sense and will leave you flabby, and I don’t think with more carbs than if you ate a balanced meal and just leaned your diet towards carbs.
Also, tapering properly,don’t taper for every event; only for A priority races…are you tapering every weekend / every race?
