A good starting point is eating half the calories you’ll burn, so ~1350. If you think it will be an intense ride, do more. A PB&J sandwich is 300-500Cal, and it’d be really hard to eat 3-4 on the ride. You’ll want another 800-1000Cal of sugar. You can put 200Cal on your bottle w a drink mix. Then you can refill with Gatorade from gas stations for another 150Cal each. You should drink 3-5 bottles on the ride - 3 if it’s cold, 5 if it’s hot. That could be enough. Add 1-2 bags of candy or cycling foods and you’ve definitely got it. And carry an extra in case you’d rather drink water.
Here are my favs that you can buy. Try REI or any cycling or running shop - kid in a candy shop vibes.
- SIS Beta Fuel Gel in Strawberry Lime, 160Cal
- Clif Bloks, any flavor, 200Cal
- GU Stroopwafel, 150Cal
I avoid granola bars cuz chewing sucks, especially if it’s hot and your mouth is dry.
There are good way to add another bottle to any bike. Strap cage mounts work well
