2-3 energy bars as necessary to sate my hunger. When I weighed 45-65 pounds more and rode 125 miles a week not 200+ 1 or 2 were plenty.

Today I got up at 5:45 and ate
1. Strong & Kind Thai Sweet Chili bar. 230 Calories.
1. Clif Mojo Sweet & Salty Mountain Mix bar. 190 Calories
1. Clif Mojo Sweet & Salty Peanut Butter Pretzel bar. 190 Calories
Total: 610

Then I went for an easy 32 mile ride totaling 754kj.

I do the same thing before my Saturday ride; last week that was 60.9 miles, 1130 feet vertically, and 1813kj without eating while riding.

I do the same thing when I don't ride and won't be having a real breakfast with my wife.

Except when working to maintain weight eating more than needed to top off your glycogen stores isn't helpful because it ends up as fat and doesn't change your need to eat while riding to satisfy your body's need for carbs as your glycogen runs out. More does increase your risk of gastrointestinal distress, especially on hard rides.

Fortunately when it comes to lunch there's real food left from yesterday's dinner at my office, and on weekends I have time to pick something up.

Astute readers will note the dogma about eating when riding over 2 hours is wrong - I don't bother on endurance rides under 4 hours. Glycogen can provide just 20% (lower intensity, training, and lower carb diets reduce the fraction) of your energy while riding, and you start with up to 500 Calories worth in your liver plus 1500 in your muscles (although that can't get back into your blood stream so you can't use what's in your upper body). I do eat when hungry on harder rides over 2 hours.

At some point you need to begin eating immediately because you're using glycogen faster than you can digest carbs and will run out, although most recreational rides aren't long and/or intense enough to cross that threshold.
