I am a slow rider (average speed ride over 20 miles 12.5 mph), 215 Lbs 5'11" the best fuel I have found for rides up to 50 miles is about 30 minutes before leave eat 3 or 4 hardboiled eggs, 1 yoke toss the rest, get dressed, prep bike. Then just before I leave, eat a tums, 1 banana and about 1/4 to 1/3 cantaloupe or big slice of watermelon. I take 2 water bottles, and a gel and cliffs bar. I will need more water in this weather, and maybe a gatoraid with extra water. That is the best fuel for me I have found so far.
