For reference, on a 2 1/2 hour ride I will generally consume two bottles of energy drink, a Cliff bar, and maybe a gel. Average speed is in the 28 to 30 km/h range with maybe 300 m of elevation gain.
I know the answer is part fitness and part nutrition, but I get the feeling that I'd feel a bit stronger if maybe I consumed a few more calories during the ride.
Feel free to respond with "dude, you need to ride more..."
