36-Hour Carb Loading Food List (Low-Residue Plan)
Field note #579 · 2026-05-30 · 5 min read
Rapid answer
For a 70 kg athlete targeting 10g/kg, the goal is 700g of carbohydrates over 36 hours. Stick to white rice, white bread, pasta, bananas, sports drinks, and gels. Avoid fiber, fat, and protein-heavy foods in the 24 hours before the race.
Carb loading requires two things: enough total carbohydrate (10 to 12g per kg body weight over 36 hours) and a low-fiber, low-fat diet so the gut does not carry unnecessary bulk to the start line. Most athletes get the carbohydrate roughly right and underestimate the importance of the low-residue part. For the why and the full protocol behind these numbers, see the complete guide to carb loading; this page is the tactical food list that executes it.
Carbohydrate targets by body weight (10g/kg over 36 hours)
| Body weight | Total carb target (36h) | Per meal (5 meals) | Per meal (6 meals) |
|---|---|---|---|
| 55 kg (121 lb) | 550g | 110g | 92g |
| 60 kg (132 lb) | 600g | 120g | 100g |
| 65 kg (143 lb) | 650g | 130g | 108g |
| 70 kg (154 lb) | 700g | 140g | 117g |
| 75 kg (165 lb) | 750g | 150g | 125g |
| 80 kg (176 lb) | 800g | 160g | 133g |

Best low-residue carbohydrate sources for carb loading
Stick to easily digestible, low-fiber carbohydrates. High-fiber foods (vegetables, whole grains, legumes, fruit skins) stay in the gut and add weight without adding glycogen.
| Food | Carbs per 100g | Fiber | Notes |
|---|---|---|---|
| White rice (cooked) | 28g | 0.4g | Ideal. Low residue, high carb density. |
| White pasta (cooked) | 31g | 1.8g | Good. Avoid whole wheat. |
| White bread | 50g | 2.7g | High density. Easy to eat in quantity. |
| Bagel (plain) | 48g | 2g | Good race-eve food. |
| Potato (boiled, no skin) | 17g | 1.2g | Moderate density, very digestible. |
| Banana (ripe) | 23g | 2.6g | Good. Ripe bananas have more sugar, less starch. |
| White rice cakes | 82g | 0.3g | Excellent density. Good for snacking. |
| Sports drinks | 6g per 100mL | 0g | Easy way to add carbs between meals. |
| Honey | 82g | 0g | High density. Add to oatmeal or bread. |
| Sports gels | 22 to 28g per packet | 0g | Dense, portable, no fiber. |
What to avoid in the 36 hours before the race
| Food | Why to avoid |
|---|---|
| Vegetables (especially raw) | High fiber, stays in the gut, adds weight |
| Whole grains, brown rice, whole wheat pasta | High fiber |
| Beans and legumes | High fiber, gas-producing |
| High-fat foods (nuts, avocado, oils) | Slow gastric emptying |
| High-protein foods (large meat portions) | Slow emptying, not needed for glycogen |
| Dairy (for lactose-intolerant athletes) | Potential GI distress |
| Alcohol | Dehydrating, disrupts sleep |
| Caffeine (if tapering) | Save for race morning |
| New foods | Never try something new before a race |
Sample 36-hour meal plan (70 kg athlete, 700g carb target)
Day before race (Day 1):
| Meal | Food | Carbs |
|---|---|---|
| Breakfast (8am) | 3 cups cooked white rice + honey + banana | 120g |
| Snack (11am) | 2 plain bagels + jam | 100g |
| Lunch (1pm) | Large white pasta bowl + small tomato sauce (no vegetables) | 130g |
| Snack (4pm) | 4 white rice cakes + honey + sports drink 500mL | 100g |
| Dinner (7pm) | White rice bowl + plain chicken breast (small) + sports drink | 130g |
| Evening snack (9pm) | 2 slices white toast + honey | 50g |
| Day 1 total | ~730g |
Race morning (Day 2, 3 to 4 hours before start):
| Meal | Food | Carbs |
|---|---|---|
| 3 to 4 hours before | White toast + honey + banana + sports drink 500mL | 90g |
| 1 hour before | 1 to 2 energy gels + 250mL sports drink | 45g |
Race morning target: 2 to 3g carbohydrate per kg body weight, 3 to 4 hours before start.
Common carb loading mistakes
- Eating too much fat or protein: Loading a pasta dinner with heavy cream sauce and meatballs adds fat that slows digestion and often causes race-morning GI problems.
- Skipping breakfast on race morning: Liver glycogen depletes overnight. A race-morning meal restores liver glycogen even if muscle glycogen is already topped up.
- Over-eating volume: The goal is carbohydrate grams, not total food volume. High-density, low-residue foods let you hit carb targets without an uncomfortably full stomach.
- Trying new foods: Race week is not the time to experiment. Use foods you have practiced with in training.
Frequently asked questions
What foods are best for carb loading?
White rice, white pasta, plain bagels, white bread, ripe bananas, honey, rice cakes, and sports drinks are the best carb loading foods. They are high in carbohydrates, low in fiber, and digest quickly. The goal is not just to eat a lot of carbs but to avoid fiber-heavy foods like vegetables, whole grains, and legumes that stay in the gut and add unnecessary bulk before the race. Sports gels and drinks are useful for adding carbohydrate grams between meals without adding significant volume or fiber.
How many carbs should I eat the night before a race?
For a 36-hour carb load, the total target is 10 to 12 grams of carbohydrate per kilogram of body weight spread across both days. The night-before dinner should contribute roughly 120 to 150 grams for a 70 kg athlete. A large white pasta bowl or white rice bowl with a small amount of plain protein is appropriate. Avoid heavy sauces, fat, and large portions of meat that slow digestion and may cause GI distress on race morning.
Can I carb load with gluten-free foods?
Yes. White rice, rice cakes, plain potatoes (no skin), bananas, honey, sports drinks, and gels are all naturally gluten-free and excellent carb loading foods. Gluten-free pasta made from rice or corn flour is also a workable substitute. The important thing is to stick with low-fiber, easily digestible options regardless of whether they contain gluten. Many carb loading staples happen to be gluten-free, so athletes with celiac disease or gluten sensitivity can meet the 10 to 12g/kg target without compromise.
What should I avoid eating when carb loading?
Avoid vegetables (especially raw or high-fiber ones), whole grains, brown rice, whole wheat pasta, beans, legumes, nuts, avocado, large amounts of fat, and large portions of protein. These foods slow gastric emptying, add bulk to the gut, or displace carbohydrate calories. Also avoid alcohol (dehydrating, disrupts sleep), new foods you have not practiced with, and anything you know from experience does not sit well before a race. Dairy can cause GI distress for lactose-intolerant athletes and is worth limiting as well.
