Decision guide
Gels, chews, drink mixes and electrolytes for training and racing — product decisions from labels and gut practice, not medical advice.
Product types
- Energy gels. Portable carbs; caffeine variants for late race.
- Chews / bars. Chewable carbs when gels feel monotonous.
- Carb drink mixes. Bottle/flask fuel for higher carb targets.
- Electrolytes. Sodium/fluid support — not a carb substitute.
What matters
- Carbs per serving you can actually stomach
- Caffeine preference (and bedtime races)
- Format you’ll carry (gel vs flask mix)
- Practice in training before race day
Specs that matter
- Carbs / serving. Match fuel plan math, not brand stories.
- Caffeine mg. Late-race kick vs sleep and anxiety trade-off.
- Sodium. Relevant in heat/sweat — not a cure-all.
Common trade-offs
- High carb density ↔ Gut comfort. Aggressive mixes need longer gut training.
- Caffeinated gels ↔ Even energy. Caffeine helps some races and wrecks others.
When use case changes the choice
- Runs under ~75 min. Water often enough unless you prefer carbs.
- Marathon / long. Rehearse timing and texture on long runs.
- Ultra. Mix formats; plan savoury/real food alongside gels.
Beginner start
For long runs over ~90 minutes, trial one gel or drink mix brand in training. Never debut a new caffeine gel on race day.
Comparisons: Compare similar formats (gel vs gel) on carbs, caffeine and texture — not gel vs jacket.
More decision factors
Decision factors — deeper detail lives in buying guides.
1. Practice in training
Format, carbs per serving and caffeine preference matter more than brand hype — trial fuel before race day.
