The initial product line of LONG HAUL Ultra Endurance Fuel includes a variety of delicious natural flavors. Right now we plan on offering 5 initial flavors for our lineup: Unflavored, Passion Fruit Orange Guava, Ginger Peach Tea, Blood Orange, and Cran Razz.
Many sports drinks rely entirely on simple sugars for carbohydrates, leading to a taste that can be nauseatingly sweet or syrupy.
Other sports drinks use complex carbohydrates, but the problem is you need to supplement with a sweetening agent, otherwise the drink just tastes like, well, dirt. Oftentimes, artificial tasting sweeteners such as aspartame and xylitol are used, leaving you paying for something that tastes like knock-off diet soda or Crystal Lite.
LONG HAUL uses a very small amount of Monk Fruit, a natural sweetener. It is nearly 200x sweeter than table sugar and has a pleasant, understated natural flavor with notes of citrus and honey.
A fair share of sports drinks out there are so salty or tart that they can be difficult to drink, especially ones that try to load up on electrolytes. LONG HAUL ingredients have been carefully sourced and proportioned to provide a delicious balance of sweetness, saltiness, and tartness.
The flavors in our lineup are designed to be subtle and inoffensive. No in your face flavor bombs.
Osmolarity is a measure of molecules, or stuff, in a solution. Blood plasma osmolarity is just shy of 300 millimoles per Liter (mmol/L). A sports drink can be categorized as either hypotonic, hypertonic, or isotonic.
Hypertonic drinks have a concentration of stuff higher than that found in blood plasma, creating a pressure gradient at the gut barrier that can reduce the efficient absorption rate of energy and nutrition. Your body is then required to shuttle water into the intestines to dilute ingested fluids before nutrients can be transported across the intestinal wall and into the blood stream. This can lead to problems during longer bouts of exercise, particularly when fluid intake is critical and dehydration becomes a concern.
Isotonic drinks have similar osmolarity to blood plasma, and hypotonic drinks have osmolarity lower than blood plasma. Isotonic and hypotonic drinks enable much more natural and efficient transfer of energy and nutrients from the gut into the blood stream for use during exercise.
It can get a bit more complicated than that, depending on perspiration rates, intensity, and duration, and, as always, there's individual variability. And we won't even get into the subtle but important distinction between millimoles (mmol) and milliOsmoles (mOsm). But the general idea is that hypotonic or isotonic sports drinks can be regarded as the most effective means to fuel and hydrate during typical training and racing for endurance athletes.
Different types of carbohydrates will increase osmolarity more than others. It is impossible to create a performance hydration formula that provides sufficient calories and electrolytes using only simple sugars such as dextrose and fructose. More than roughly 100 calories of simple sugars per 16 oz (500 mL) and a drink becomes hypertonic.
LONG HAUL Ultra Endurance Fuel has been designed to be hypotonic at a typical use rate of 200 calories per 20 oz (~200 mmol/L, or ~250 mOsm/L). The transfer of energy and nutrients from your gut into your blood stream is optimized, reducing the likelihood of encountering problems due to gut distress, low energy absorption, or dehydration.
Our primary ingredient is a fast-absorbing long-chain glucose polymer called maltodextrin. It is a complex carbohydrate, as opposed to a simple sugar such as dextrose and fructose. Simple sugars are carbohydrates with smaller molecules than long-chain complex carbohydrates. Smaller molecules means more stuff in your bottle. Sports drinks that rely primarily on simple sugars will have too much stuff , becoming hypertonic in concentrations as low as 100 calories per 16 oz of water.
Leveraging a rapidly dissolving maltodextrin, LONG HAUL Ultra Endurance Fuel can be readily absorbed in solutions nearly 3 times as concentrated. This increases flexibility of use in training and on race day.
Fructose is absorbed through a different pathway than glucose / dextrose / maltodextrins. Therefore, consuming fructose increases the amount of energy that can be readily provided to muscles during exercise.
However, LONG HAUL Ultra Endurance Fuel contains 40% less fructose than many other sports drinks in order to minimize the likelihood of gut distress and to reduce osmolarity.
The 4:1 Ratio
LONG HAUL Ultra Endurance Fuel contains 25 grams of carbohydrates (100 calories) per serving in a 4:1 ratio of Maltodextrin and Fructose.
The body has 2 primary pathways for processing carbohydrates, with studies showing that glucose / dextrose / maltodextrins can be absorbed at a rate upwards of 60 grams per hour and fructose at a rate upwards of 30 grams per hour.
Exercise nutrition studies, typically focusing on cyclists and marathoners, have commonly shown that the 2:1 ratio is more efficient and more effective (though not necessarily optimal) than consuming no fructose at all. For this reason, many sports drinks utilize this 2:1 ratio. For athletes pushing the envelop to run, say, an Olympic Trials Qualifying time, maximizing every carbohydrate pathway during intense exercise while trying to cram in nearly 400 calories per hour might make sense when every single second counts.
But for athletes performing at a lower overall intensity than that of elite marathoners, maximal absorption is generally unnecessary as a much lower total carbohydrate load is required.
Moreover, many athletes experience gastric distress from hour after hour of fructose ingestion -- the more limited fructose pathway becomes overburdened during long bouts of exercise, reducing absorption and causing gut issues.
In particular, the body's limited capacity for processing fructose can cause unexpected problems, especially on race day. Take, for example, an ultramarathoner with a race day plan to consume 300 calories per hour. That's 25 grams of fructose each hour in a typical 2:1 ratio. Theoretically, there is 5 grams of wiggle room. But what if they roll into an aid station and are suddenly jonesing for a can of ginger ale? Well, soda is made with high fructose corn syrup in a 55% concentration, so that 5 grams of spare fructose translates to less than 3 ounces of soda. A quick hankering for a drink or a handful of fresh fruit at an aid station has the potential to quickly derail a carefully crafted nutrition strategy by overloading your gut with fructose.
LONG HAUL Ultra Endurance Fuel eschews the standard 2:1 carbohydrate ratio for 4:1. This still enables the delivery of a hefty load of energy while also providing enough flexibility to avoid common gut distress issues due to fructose ingestion.
Sweat is more than just salt!
There are 5 primary electrolytes found in sweat: SODIUM, CHLORIDE, POTASSIUM, CALCIUM, and MAGNESIUM. The longer you exercise the more critical it is for you to replace what you lose in order to maintain optimal nutrient levels for proper cellular function.
Electrolyte offerings in sports drinks run the gamut. Some provide way too much, others not enough, and some minerals are even ignored entirely.
We looked at scientific research to create a mix of electrolytes that would satisfy the needs of endurance athletes. LONG HAUL Ultra Endurance Fuel is designed to mimic sweat when mixed at 1 serving (100 calories) in 10 oz (300 mL) of water.
Men and women sweat out electrolytes not only at different rates (mg/hour), but also at different concentrations (mg/L of sweat). Most scientific studies lean heavily towards male athletes. As a result, the few endurance drinks that seem to provide adequate levels of electrolytes are actually doing so only for males. For the most important electrolyte, Sodium, studies show that males sweat at a rate 1/3rd more concentrated than females. LONG HAUL Ultra Endurance Fuel electrolyte concentrations are designed to thread the needle and provide slightly less than an average male would need and slightly more than an average female. For an overwhelming majority of activities, this ensures a tolerable amount of electrolytes for nearly every athlete. Gender Equality with Electrolytes!
Few sports drinks contain amino acids -- the building blocks of protein. The longer you exercise, the more important it is to protect and repair your muscles. Free form amino acids are many times more effective at supporting muscle protein synthesis compared with complete proteins such as whey. Additionally, unlike whey or other protein supplements, free form amino acids are easily absorbed during exercise and do not cause gut distress.
LONG HAUL Ultra Endurance Fuel contains an effective dose of amino acids to control fatigue, enhance energy levels, and jump start the recovery process.
Essential Amino Acids
LONG HAUL Ultra Endurance Fuel contains the 3 Branched-Chain Amino Acids (BCAA) -- Leucine, Isoleucine, Valine -- in an optimal 2:1:1 ratio. BCAAs can help preserve muscle glycogen stores to reduce exercise fatigue.
Glutamine is the most abundant amino acid in the body. During long bouts of exercise, muscle synthesis of Glutamine is insufficient to meet your body's requirements. By providing Glutamine in LONG HAUL Ultra Endurance Fuel, supplementation helps prevent muscle tissue breakdown.
A small amount of Theanine is also provided in LONG HAUL Ultra Endurance Fuel. Recent studies indicate that Theanine may help to enhance mental clarity and focus during exercise. Moreover, when paired with Caffeine (caffeinated Long Haul products will be available in the near future), it can help to mellow out any potential caffeine jitters or anxiety. Yeah, it may sound hokey, but who knows, it might provide just the thing you need when it's 3am and you're at Mile 80 of a brutal 100 Mile race!
As an Amino Acid, Glycine is critical for muscle development, but it likely has no direct benefits during exercise. In all honesty, it's a bit of a freebie in LONG HAUL Ultra Endurance Fuel because it is bound to Magnesium in the ingredient Magnesium Glycinate.
