On a bike, effort is different from running: less impact, often longer, and a much greater capacity to carry your nutrition with you. But that freedom brings its own trap: without a clear plan, it's easy to forget to drink or eat until the fatigue hits. Here's how to structure your bottles, frequency, and dosing for your long rides.
1. How many bottles for a long ride?
For a 2 to 3 hour ride, two bottles are usually enough: one for your endurance drink, one for plain water. Beyond 3 hours, plan for a refill stop along the way, or a third bottle if your bike allows it.
A common mistake: filling every bottle with concentrated drink. Always keep one bottle of plain water available, especially in hot weather, so you can adjust concentration based on your needs.
2. How often should you drink and eat?
Unlike running, where every sip takes extra effort, cycling makes it much easier to drink often. A good routine:
- One sip every 10 to 15 minutes, rather than large amounts spaced far apart.
- A simple cue: drink on every descent or terrain change, a natural moment when effort eases up.
- Don't wait until you're thirsty: on the bike, wind cools your skin and masks dehydration signals.
3. The right carb dosing for cycling
Carbs-per-hour targets stay similar to running, but cycling generally tolerates higher intakes thanks to the lack of repeated stomach impact:
- Moderate ride (under 2h): 30g to 45g of carbohydrates per hour.
- Long or intense ride (2h+): 60g to 90g of carbohydrates per hour.
A slow-release carbohydrate like isomaltulose is especially useful on the bike, where rides often stretch over several hours without a real break.
4. Electrolytes: the cyclist's blind spot
The wind created by movement evaporates sweat quickly, giving the misleading impression that you're sweating less than you would running. In reality, your sodium losses stay just as significant, especially on climbs or in hot weather. Neglecting electrolytes is one of the most common causes of cramping late in a long ride.
5. Where Eracer fits into your long rides
Our formula combines slow-release carbs and complete electrolytes in a format that's ready to pour straight into your bottle. No powder to measure on the side of the road, no recalculating every ride: fill up, ride, and keep your energy stable all the way home.
Test your bottle routine in training before your longest rides or events, every cyclist has a different hydration rhythm, and it's by repeating it that you'll find yours.
