Last weekend's experience on a 23 mile ride: Breakfast, whole wheat cinnamon raisin bagel and a banana. Hydration pre-ride, not much. During ride no food as is usual for me and a 70 oz camelback. Hottest day of the year so far caught me off guard.....I didn't drink enough and ended up paying for it with a headache.


I've always got food on hand and will eat a little here and there if I need it. For me hydration or lack of it is what really affects me most.
