Top 7 Nutrition Tips for Trail Runners

Fuel smarter to go farther — before, during, and after the trail.

Trail running pushes your endurance, strength, and mental focus more than typical road runs. The unpredictable terrain, elevation changes, and longer distances demand a well-planned nutrition strategy to perform well and recover quickly. Whether you're tackling a 5K trail or training for an ultra, these seven nutrition tips will help you stay energized and resilient — on every terrain.

1. Start Fueled: Pre-Run Nutrition Matters

Eat a well-balanced meal 2–3 hours before your run with a mix of complex carbohydrates, lean protein, and healthy fats. This ensures stable blood sugar and long-lasting energy.

Pre-run meal ideas:

• Oatmeal with banana and peanut butter
• Whole grain toast with eggs
• Smoothie with yogurt, berries, and a scoop of protein

Optional add-on:
Top up 30–60 minutes before your run with a light snack or energy bar, like the SiS GO Energy Bar or a Maurten Drink Mix 160 for sustained energy.

2. Hydration Starts Before You Hit the Trail

Hydration is more than just water — you need electrolytes to prevent cramps and maintain muscle function. Start hydrating 1–2 hours before your run with a low-calorie electrolyte drink.

Recommended products:

• SiS Hydro Tablets (effervescent tabs with sodium, potassium, magnesium)
• Amino Vital Hydration Stick for amino acids + electrolytes

3. Fuel Early, Fuel Often During Long Runs

If your trail run lasts longer than 60–90 minutes, bring fuel. Aim to consume 30–60g of carbohydrates per hour, depending on intensity and duration.

Trail-ready options:

• SiS GO Isotonic Gels — no water needed, fast energy
• Maurten Gel 100 — dual-source carbs, gentle on the stomach
• Amino Vital Perfect Energy — energy gel with amino acids for added endurance

Rotate between gels, chews, or drink mixes to avoid GI distress and flavor fatigue.

4. Electrolytes Are Key, Especially in Heat or Humidity

Sweat doesn’t just dehydrate — it drains your body of vital minerals. Without replenishment, you risk cramps, fatigue, and brain fog. For long or hot runs, add electrolytes to your water.

Electrolyte solutions:

• SiS Hydro+ (includes carbs + electrolytes)
• Salt caps or LMNT as alternative options

5. Recover Fast: Don’t Wait to Refuel

Post-run recovery is critical for muscle repair and glycogen replenishment. Within 30–60 minutes of finishing your run, consume a mix of protein (15–25g) and carbs (30–60g).

Recovery options:

• SiS REGO Rapid Recovery (carbs + protein combo)
• Whole-food smoothie: banana, protein powder, oats, almond milk
• Add MuscleUp Creatine (4g sachet) to support strength and repair

6. Adapt Your Nutrition to Trail Conditions

Trail running isn’t flat or predictable. Hot days, steep climbs, and technical descents all change how much fuel you burn. You may need more carbs, sodium, or fluids than you would on the road.

Pro Tip:

Pack extra fuel on race day or long runs just in case you go longer than expected. Small gels or electrolyte sticks fit easily into a running vest or belt.

7. Practice Your Nutrition Strategy in Training

Never try new gels, drinks, or foods on race day. What works for others might upset your stomach or leave you bonking mid-trail. Use long training runs to test products, timing, and quantities.
