I really like high carb drink mixes like Formula369, GU Roctane, etc. Can easily get 180g of carbs in 500mL of water. Probably way more. Still drinks like liquid instead of thick like gel.

Have you considered ditching syrup for a liquid high carb drink mix? On my weekend 2.5 hour long run I took two 500mL soft flasks: one was 6 scoops of GU Roctane powder (about 177g of carbs and 105mg caffeine total) dissolved in 500mL of water, and the other was just water. The drink mix was not thi

Are you drinking any water on your runs? It sounds like no. Gels will pull water into your gut and can cause cramping, bloating, nausea, diarrhea, etc. I switched to high carb drink mix instead and have zero discomfort. I am now up to 80g/hour of either GU Roctane (with caffeine) or Formula369 (with

I used gu roctane for my first half and then bought ingredients on amazon to customize it slightly for my second and training. My dad who has done a bunch of fulls uses gu and hammer drink mix. Whatever tastes good and works for your stomach tbh.

Have you considered using a high carb drink mix instead? I make 90-120g mixes with Formula123 or GU Roctane powders, add a bit more electrolytes to balance the sweetness, and away I go. They dissolve easily, and will save you a couple dollars per gel. Doesn't have that thick gel or Maurten gloopy te

You can train what's called repeatability. Basically you do reasonably short intervals a good number of times, ideally with limited rest and tailored to the next racecourse. If you're new, you should see big gains reasonably quickly doing 2 interval sessions a week for 4 weeks, with a plateau after

Just seeing that OP is still in high school. You’re going to want at least 50-100 grams of carbs per hour. If you were just doing the ride, 50 would usually be enough, but since in the race, you’ll have a whole marathon after the ride, you need to use the ride to overfuel so you’ve got energy for th

Drink your carbs! Skratch High Carb drink mix (50g carbs /200 cal) or Gu Roctane Energy drink mix (59g carbs / 250 cal). I like the Gu drink mix bc it also has caffeine and additional calories. Easier to drink the carbs than having gels so frequently.

No, but to be fair, I’ve never had any gastro issues using whatever drink mix or food that happened to be available at neutral aid stations at the endurance mtb races I’ve done. I’m using GU Roctane drink mix right now. Three scoops is 90 gr of carbs. The only issue is that it seems like a 21 oz bot

Hyperlyte is pretty good but I don't think it is flavored (at the bags I bought weren't). It's pretty much just maltodextrin, fructose, and sodium so it kind of tastes like maltodextrin. Similarly, The Feed brand high carb mix tastes like maltodextrin. GU Roctane grape and summit tea (caffeinated) a
