Kind of what I did with the EFS mocha stuff. I put 2 of the EFS mocha shots into a bottle and topped up with water in a normal water bottle. That goes on my downtube and is the bulk of my calories. I have a between the bars bottle that I have water in (going to use EFS drink mix this year instead), and get water refills for it at the aid stations. I usually grab a gel or two from the aid stations as well during the bike for a little extra. That is my bike nutrition for the most part for the 70.3 bike.
