First, and I'm sure you know this, cut any additional cardio/ESW. I know I wrote about long walks, Xvest walks etc, but obviously you don't need that with your two-wheeling ways.
If the rides are strenuous and there's no way to avoid them, then time a regular V-Diet Low-Carb Grow! shake for after. I don't think I'd add extra Surge. Save that for the iron. However, if you really do need some nutritional support, have one scoop of Surge after the rides.
