(all my Calories are in my bottles. 24 to 25 oz bottle last me 50 minutes). Other cyclist will vary on how much sugar they can tolerate. There are studies that show how much the average person and average athlete can digest/absorb while cycling. Everyone should find their own limits when they don't have a professional trainer, coach, dietitian or other monitoring them.
