Hey @rostonnordell!
What will work best for you will take some time testing out different products, but my personal favorites is Gu Roctane. We have a partnership with Gu too, so you can get a discount on the Gu Roctane using your fascat discount. I guess you could say that is a sponsored, yet nonsponsored recommendation as I used Gu roctane long before joining the fascat team. I love the grape and summit tea flavors.
I do like tailwind too however, it is a bit sweeter and find that for really long races that the sweetness causes me to get upset stomach.
** Most gels these days contain very close to a 2:1 ratio too and you can combine those with hydration mixes to achieve the ~90g per hour. For example, using 1 scoop of a hydration mix (~40g carbs) + 2 Gu roctane gels per hour (46g carbs).
Also interesting to note, new research is showing that some athletes can tolerate a 1:1 glucose fructose ratio with absorption up to 140g/hr rather than just the 90g tops that has been assumed for a while now. On the other hand from experience working with athletes, some with sensitive stomachs cant handle more than 75g/hr during intense efforts (more common with females).
Intolerances aren’t always permanent though as the more you “train your gut” to eat while you train, the more glucose and fructose transporters your body will upregulate (aka make more of) in your stomach, allowing you to take in more carbs during training. This is yet another reason why I will never advocate a low carb diet to an athlete (especially during race season). The science just doesnt support it.
But again, what works best for you just depends on you… so practice, practice, practice your nutrition so you have no worries about it come race day!
