- SPEED High-intensity Fuel All-in-one 230 Calories Per Serving Sport Hydration Drink Mix - No Gels, Bars, or Salt Pills, Natural Carbs, Electrolytes, Gluten Free, Vegan Lemon-Lime Flavor

I switched to Infinit Nutrition several years ago to help both my running and cycling training and races. I love both the custom formulas as well as the preset formulas such as Speed and Go Far. My favorite flavor is lemon lime, and I love how the Speed formula supports my workouts with the right amount of carbohydrates and electrolytes to keep me fueled for my shorter, high intensity workouts. Infinit Nutrition prevents muscle cramping and supports peak performance both in training and racing. It also prevents stomach distress with a pure and naturally isotonic mixture. If you are looking for something to support your training, I highly recommend Infinit and think you will love the Speed formula for your high intensity workouts!

Usage - CyclingI have been using Hammer Heed products for a while now trying to keep leg cramping at bay. For most races and long ride the Hammer Heed worked ok, but I usually had to use Salt Tabs. Since switching to Infinit I have not had to supplement the drink mix with anything, even during long rides. This is a welcomed relief. I would often forget to take the salt tabs and that would result in cramps.The flavor reminds me of old-school Gatorade. It is good and I have no complaints. It even isn't that bad warm. I will be using this from now on!

I’ve tried other mixes and this one doesn’t make me feel bloated. The flavor is good (not too strong/not too weak). I use this during weight training and 2-3 hour bike rides and haven’t had any gastro issues. Everyone is different so try a couple of packets before committing to this large bag.

The product is fine, I tried some of my friends' during a training ride and planned to use it for my 32 mile mountain bike race on July 31st. The product arrived late (ordered Monday, didn't arrive until the following Tuesday) and I wasn't able to use it in time for my race. My friend gave me some scoops of hers for the race. So now I have an unopened giant bag I spent $46 for and my race season is mostly over for this year, and I can't return it, despite the page saying it's returnable or refundable IF it arrives damaged. Though there's no way to get in touch with the seller anywhere because it just goes to the Amazon IM and keeps giving you an automatic response: not returnable.I had hoped to use it 'in place of' Gu and other packets, and be able to miss aid stations to save time. Take note that instructions say you have to drink a bottle per hour in order to NOT use any other replacements. This is difficult during a 3 hour race unless you pre-mix 3 bottles, which I don't have room for (can only really carry 2). SO. In my review, it has it's place, and tastes fine, but possibly not what I was looking for in the long term. If you buy, make sure you have already tried it because it's a huge bag.

I have used a wide variety of calorie/electrolyte powders over the years for cycling. Beta Fuel is still my #1, but it's pretty expensive so I only use it on really vigorous ride or on race day. This powder is my go-to for my regular training rides. It works well, tastes okay, and isn't too expensive. I'll likely continue using it for years to come. Highly recommended!

Infinit speed is my go to supplement for long (>2 hr) bike rides. The lemon lime has great taste and the calorie mix provides sustenance without upsetting my stomach. It does as good or better for hydration than skratch but has the added benefit of 230 cal per serving (bottle). I prefer the flavor vs tailwind.I also prefer this to Infinit’s custom mixes. Getting the flavor right on them is hard and the price is $$$...

Product works great! I noticed a significant difference using this product vs not. My bike rides feel much easier than just replenishing with water. I use two scoops in a 24 oz bottle as my main fuel for a 10 mile ride. I’m drink half before and half midway through my ride. No more cramping or exhaustion like before with just water. Look forward to upgrading my fuel for longer rides

For a workout product I’ve got to say I think it works, I seem to get less cramps and I reckon I go harder when I’m on it ….. but the indigestion and after taste is very chemically and just not nice. Think I’ll try a different flavor or brand next time
