Nutrition Guide

Fuel your runs right. What you eat before, during, and after running directly impacts your performance and recovery.

What you eat before running determines how you feel during it. Timing and food choices both matter.

🕐

3–4 Hours Before

Full meal

The optimal window for a full pre-run meal. Your body has enough time to digest and convert food into usable energy. Ideal before long runs, races, or high-intensity sessions.

Complex carbohydrates: oatmeal, whole grain toast, brown rice, sweet potato
Lean protein: eggs, Greek yogurt, chicken breast, cottage cheese
Moderate healthy fats: nut butter, avocado in small amounts
Fluids: 16–20 oz of water with the meal

Example: Two slices of whole grain toast with peanut butter and a banana, plus a glass of water and a small serving of Greek yogurt.

🕑

1–2 Hours Before

Light snack

Focus on easily digestible carbohydrates with a small amount of protein. Minimize fat and fiber — both slow digestion and can cause discomfort mid-run.

Banana with a tablespoon of nut butter
White rice with a small portion of chicken
Energy bar with simple ingredients (less than 5g of fat)
Toast with honey or jam (no heavy spreads)

🕒

30–45 Minutes Before

Very small snack

Keep it very simple. The stomach is sensitive and a heavy snack now can cause cramps or nausea. Stick to fast-digesting carbohydrates only.

Half a banana or a few dates
One energy gel or chew with water
4–6 oz of a sports drink
A small handful of gummy bears or similar simple sugar

Foods to Avoid Before Running

✗High-fiber vegetables (broccoli, beans, lentils, cruciferous greens) — Cause gas and cramping

✗Fatty or fried foods — Slow digestion, sit heavily in the stomach

✗Dairy in large amounts — Can cause bloating and digestive distress in many runners

✗Alcohol — Dehydrates, impairs glycogen storage, disrupts sleep and recovery

✗Excess caffeine — Moderate caffeine can be beneficial, but too much causes jitters and urgency
