Commercial sports drinks cost $1.50-3.00 per serving, adding $200-500 annually to your ultra running nutrition budget. Meanwhile, a DIY sports drink recipe delivers identical electrolyte content and carbohydrates for $0.15-0.40 per serving using simple kitchen ingredients. These proven homemade electrolyte formulas have fueled countless 100-mile finishes while saving runners thousands of dollars.
The Science Behind DIY Sports Drinks
Effective sports drinks require three components: carbohydrates for energy, sodium for fluid retention and absorption, and water for hydration. Commercial products add flavorings, preservatives, and artificial colors you don’t need—and charge premium prices for the privilege.
What Makes Sports Drinks Work
Carbohydrates (6-8% solution): 14-19g per 8oz serving Sodium: 110-165mg per 8oz serving Osmolality: 200-330 mOsm/kg for optimal gastric emptying
Your DIY sports drink recipe can match these specifications using sugar, honey, salt, and citrus—costing pennies versus dollars.

Batch Preparation for Training and Racing
Weekly Training Concentrate
Makes 1 gallon (serves 20-25 training runs):
- 1 gallon water
- 1.5 cups sugar
- 2 tablespoons salt
- Juice of 6-8 lemons
Store in refrigerator, use within 7-10 days.
Cost: $2.50 total vs $30-40 for commercial equivalent Savings: $27.50-37.50 weekly
Race Weekend Protocol
Make fresh batches 1-2 days before race: – Standard formula for early race (easy digestion) – High-carb formula for mid-late race (maximum energy) – Low-sugar formula for between aid stations (hydration focus)
Transportation and Storage
For Training Runs
Reusable bottles: Fill standard water bottles Soft flasks: Use for handheld carrying Hydration bladder: Perfect for vest systems
For Race Day
Drop bags: Pre-mix bottles, label clearly (“Mile 30,” “Mile 60”) Aid station strategy: Bring concentrated mix, dilute at stations Emergency backup: Carry salt and sugar packets to make on-the-go
DIY vs Commercial: The Economics
Annual Cost Comparison (3 ultras + 50 training runs)
Commercial sports drinks: – Training: $225 (2-3 bottles per long run) – Racing: $60 (3 races) Total: $285 annually
DIY sports drink: – Training: $25 (ingredients for 50+ liters) – Racing: $5 (fresh race batches) Total: $30 annually
Annual savings: $255 (85% cost reduction) 5-year savings: $1,275
