Interesting, I might have to give some of these a try (I’ve had the maurten powder and it was decent). Do you skip the powerade at the hydration stops? That was one issue for me this past weekend, I had a rotation of salts and gummies I had been using for practice runs but of course at the races they have gatorade endurance at the stops so I ended up drinking that as well sometimes. I wasn’t sure if that might not be the best idea.
I don't consume any provided nutrition on marathon courses. Only water. I carry all of the above in my shorts pockets (link). I mix the Tailwind in a 5oz Hammer Nutrition flask at 3 scoops and 5oz water (link). It forms a slushy material that is not completely solubilized, but is enough to make it a drinkable solution.
It's important to keep in mind the gut absorption of the carbs you're taking in. In almost all cases, you need to take in about 1oz water for every 2 grams carbs consumed. So if you eat a 25g carb GU gel, then you need 12.5oz of water to properly absorb it. If you drink 1 scoop of Tailwind (25g carbs) in 1.5oz water, you still need to drink 11oz of water to properly absorb it. Assume a standard race cup as 3 oz of water in it.
Maurten gels are an exception. They are isotonic in their packaging and thus require no water to be properly absorbed. In addition Maurten 320 is unique in that instead of a 2g carb to 1 oz water ratio it is 4.2g carb to 1 oz water. So both Maurten products reduce the need for extra water consumption for the purpose of gut absorption.
So where people sometimes get in trouble is they eat the carbs, but they don't drink enough water to properly absorb it. When that happens, the body may steal water from other areas of the body and send it to the gut in an attempt to absorb the carbs. So you can exacerbate dehydration when that happens. Gatorade if properly made (and that doesn't always happen on race courses depending on a variety of factors) is already 1 oz water to 2 g carbs. So if you eat a 25g carb GU, you can't drink 12.5 oz of Gatorade for the purpose of gut absorption. The Gatorade is already 2:1. You have to mix other sources of carb consumption (gels, chews, gummies) with water, not gatorade. You can consume both gummies and Gatorade, but the gummies need water too. So then it would be gummies + Gatorade + water for proper absorption.
