There are a few four letter words we really shouldn’t use in polite conversation. Worst of them all is, “BONK.” That awful, drained feeling that occurs about 2 hours into any ride occurs largely due to nutrition, predominately your nutrition immediately before and during the race. Here is what and when to eat to avoid bonking.
Three days before your ride is your carbohydrate loading period. More archaic methods have suggested you go low-carb for three days before your loading period, but in this case, the drawbacks don’t outweigh the benefits. Therefore, our recommendation is that you skip it altogether. Your normal diet probably consists of about 6 grams of carbohydrate per kilogram of body weight per day – about 435g for men or 340g for women. Or at least it should assuming you weigh in at 57-70 kilograms (how to determine ideal diets for cyclists and endurance athletes can be found HERE).
During your three-day carb loading phase, increase your carbohydrate intake by about 2g/kg to 8-10 grams per kilogram per day. To figure this out, divide your weight in pounds by 2.2 to get your weight in kilograms, then multiply that number by 8, or 10.
An example: I’m 154 pounds. 154 / 2.2 = 70 kg. I eat 490 grams of carbohydrate per day, so I currently eat 490g / 70kg or 7g/kg. For my carb load, I want to increase to 9g/kg, so that means 70 * 9 g = 630 grams of carbohydrate per day.
Some of you out there are ketogenic and thinking, “I don’t bonk, I’m keto!” True, you won’t exhaust your fat stores, but you still want to carb load. I know you don’t think you want to, and you don’t think you have to, but you do… if you want to perform your very best. You’re still going to be using carbs if you’re trying to cycle fast – just less than you would on a carb-based diet. The protocol is a little different, though. Only carb load the 24 hours prior at 6 grams of carbohydrate per kilogram of body weight.
On either diet, some of the best carb-loading foods are whole grain pasta, rice, potato, oats, granola, and whole grain bread. Drinking your carbs or eating some honey, jam, or chocolate are acceptable options as well if you just can’t stomach that 6th sweet potato. It’s important not to skimp out on your other nutrients just to get the carbs in. Protein and fat slow digestion and improve carbohydrate absorption.
Some of you are going to notice and care about weight gain. It’s just carbs and water (those things have weight!). Don’t worry about it. It will all be long gone by the end of the ride.
Even though you’re riding in the morning, it’s still a good idea to get in a small meal of more simple carbohydrate, like fruit or a sports drink 30-60 minutes prior with your PerformElite. If you can stomach a full meal, go for it, but most riders feel a little bit of an upset stomach if they eat too much right before riding. Figure out what works best for you. If you're an early riser, a small meal of 60-100g of starchy carbs 2-3 hours pre DK200 can help top off glycogen stores, then follow the first guideline!
Now for the fun part. Fueling during the ride. For nearly everyone in this ride, 60-90 grams of carbohydrates per hour will be your sweet spot. It all depends on what type of athlete you are and how much you’re pushing the limit. If you’re riding just for the sake of finishing and having a great accomplishment, 60g per hour is for you. However, if you’re very well trained and trying to lead the pack, you will need up to 90g per hour to get you over the finish line.
For the super competitive riders, you may need even more. However, it is only even possible if you train your gut and utilize glucose and fructose intestinal transporters. How do you train your gut? Periods of at least 1 month consuming a diet of at least 6.5g carbohydrate per kg bodyweight per day of which 1.5g per kg bodyweight is consumed during training sessions. For this ride and all races lasting at least 5 hours, up your carb intake to 90g per hour after the first 2.5-3 hours. Also, because this is a long, grueling ride, consume another scoop of PerformElite after 5 hours. If you're expecting to finish in 12-13 hours, we suggest another 0.5-1.0 serving of PerformElite at hour 8 or 9 to ensure a strong finish. If you're expecting to finish in 15+ hours, we suggest another full serving of PerformElite at 10 hours.
Lastly, about 10% of your calories should come from protein and/or branched-chain or glucogenic amino acids. These will help prevent muscle damage and serve as intramuscular fuel substrates that have proven benefits for enhancing endurance performance.
Yes, we hear your ketogenic people! The research is currently non-existent on what is best for you. Our personal observations are that you should still be having some carbs before and during exercise. “Won’t that knock me out of ketosis?” Yeah, it will… For a few hours until the next time you eat fat or start exercising heavily. Being "in ketosis” is overrated. Do you want to be in ketosis or do you want to win? Fact of the matter is, you will still have all the benefits of being ketogenic, plus you will have enough carbs to race at a higher intensity. During exercise, our recommendation is to still have at least 60g per hour (and some MCTs IF you can stomach it). At that amount, the carbs will almost instantly disappear. You won’t regret the carbs when you’re standing on the podium.
The waters get a little murky around fluid recommendations. Pun intended. You may hear recommendations anywhere from 6 ounces per hour to 36 ounces per hour. This information varies depending on the sport (i.e. cycling vs. running), fluid pacing (i.e. 6 ounces in 15 minutes vs. 24 ounces in 15 minutes) and your individual capabilities. Luckily, cyclists have less issues consuming necessary fluids than runners.
Let’s start with some background. The stomach can handle about 50 mL of water per minute. Much more than that, and the fluid just sloshes around in there. Yuck. Thus, it is recommended to consume about 750 mL of fluid per hour spread out evenly over the entire hour. In other words, about 25 ounces. If its hot on ride day, you may need up to 40 ounces per hour.
Obviously, the most efficient way to fuel and hydrate is to do so simultaneously with a sports drink. Even gels need to be consumed with some amount of fluid. Any source of carbohydrate works in theory, but like any competitive soul, we want the best. Lucky for you, we’ve created the perfect sports drink for endurance athletes, SustainElite. We’re not just saying that – we wouldn’t be here if we didn’t honestly feel that this is the best sports drink available.
First, see above to figure out how much carbohydrate you need each hour during the WBR500. Each scoop of SustainElite contains 30g of carbohydrate, so you will want 2 or 3 scoops! Sports drink consumption can be reduced if/when consuming food or other carbohydrate supplements - just don't forget about your hydration! During training sessions, try to figure out how much fluid you can comfortably tolerate each hour. Mix your SustainElite into that amount of fluid. Although we recommend 16 ounces for a 6% carbohydrate solution, SustainElite can be mixed in as little as 8 ounces of water per scoop, but it will still taste great, just a little less sweet, in up to 24 ounces per scoop if you need a little more fluid replacement. Just remember to give it a shake before you drink!
