    Absolutely Fantastic!

    Posted by Erin on 2nd Nov 2016

    I am beyond impressed with this product! Saw a recommendation for it on a Spartan community FB post and I am so grateful that I stumbled upon it. In the past I have suffered from severe calf cramping during races where the terrain is particularly rough. However, with Tailwind I was able to sail through the Dallas Beast with zero cramping and it was the best feeling ever! So far, my favorite flavors are Lemon and Tropical Buzz! Seriously, try Tailwind. You won't be sorry!

    Too good not to try it

    Posted by Diana Lunsford on 12th Oct 2016

    I took the Tailwinds Challenge in early September. I ordered Green Tea (2), Naked and Mandarin Orange. I am training for the Barbados marathon which will be my 20th marathon. I've run with GU, Clif bars, powerade, gatorade, nuun, Endurox, Accelerade, UCan and I always kept a stash of salt tablets in my belt. In previous marathons I have struggled with GI issues and hitting the wall so I was intrigued by the claims that both those issues could be alleviated with Tailwinds. More accurately, I was optimistically skeptical. The packaging was fun with my name written on the outside of the bag and a personal note included in the box. Impressive attention to detail. As I read the instructions I was concerned about drinking that much fluid during a race. It's more than I normally consume and I didn't want potty breaks for the threat of sudden flooding! I emailed and received a quick response encouraging me to trust the intake suggestions. I use tailwinds for all my training runs. I run 6 days a week and I have maintained a monogamous relationship with no additions or variances over the past month. I AM BLOWN AWAY! I haven't had any GI issues, I feel great on my runs - even my 1 mile repeats seem easier. I ran a half marathon 2 weeks ago just to practice refilling my tailwinds at the water stops. I bought small jewelry zip bags from a hobby shop and filled them each with 1 scoop of Tailwinds. My hydration belt has 10 oz. bottles so I dumped the mix and then grabbed a water at the stop to refill the bottle. It's simple and didn't eat into my pacing anymore than a regular walk thru the water stop. My goal was to treat the race like a long run pacing 30-45 seconds slower than MP and simply work out the refill process. Instead I maintained MP and felt great all the way to the finish line! Prior to the half, the farthest training run at MP was 8 miles so this was a welcome surprise to stack on 5 more MP miles without leg fatigue or "the wall." My only 'con' comment is the zip grip on the bags is tricky to seal. I moved my Tailwinds into an empty UCan container which is much more manageable. I'm grateful for the cost savings of the bags but the seal could use improvement. Mandarin Orange is my least favorite flavor but I appreciate the variety it adds. On light running days when you use 1 scoop/20 oz. none of them have much taste. I am a HUGE believer already and cannot wait to run the Barbados marathon with Tailwinds!

    Great endurance nutrition.

    Posted by JOhn on 7th Jul 2016

    My daughter and I have been using Tailwind for the last two years for paddleboard distance races. We're again traveling to Hawaii in July for some arduous channel crossing races between islands. Tailwind has been the go to product for us along with some additional food and electrolyte supplement to keep us topped off. We like the light taste and general make up of the product to keep us going 27 to 32 miles on the water!

    Still testing, but so excited

    Posted by Alexandra Konet on 5th Jul 2016

    Tailwind popped up in my Facebook ads one day--something I generally don't listen to. But, they caught me on a day where I had bonked on a not-that-long run. I felt like I'd tried it all--Hammer, Gu, Honey Stinger, Fluid, Skratch--with little success. I have two big issues: a sensitive GI tract that leaves me either with heartburn or running to a port-a-potty, combined with an irritating brattiness that causes me to not hydrate/take in nutrition if I don't like or get tired of the taste. Here's the deal: I'm not an elite athlete. I'm a back-of-the-pack, salty-sweating, chubby triathlete training for a half ironman that I'll be lucky to finish in the 8.5 hour window. I'm not a podium athlete, and on occasion get chased by the SAG pick-up van. Turns out, not just elite athletes need to figure out their nutrition, and it's probably *more* important for a back-of-the-packer to carry her own nutrition since stations are occasionally shut down when you're slow. I started with the sticks. Promptly determined the caffeinated buzz flavors weren't for me (see port-a-potty comments above), but wasn't 100% sold. Part of this was my fault--I was still carrying and using chews because I didn't trust the Tailwind. Went ahead and ordered a couple medium bags. Finally did a brick of a 30-mile ride with a 3-mile run on only Tailwind. I felt fantastic. So I took the challenge. The longest I've gone on Tailwind so far was a 4-hour brick with a 50 mile ride and a 2.5 mile run. I carried--and actually consumed!!!--1000 calories worth. No side effects whatsoever. My favorite flavors are the Naked and the Mandarin Orange. I love the Green Tea, and would buy it if it came in a caffeine-free version. The flavors aren't overly intense or overly acidic, and taste good cold and warm, which is ideal since even when some is frozen it inevitably thaws when it's 90 degrees out. My event isn't until August, but I've started training with only Tailwind, and have turned a few of my teammates and my coach on to it. We're all a little stunned still, but I'm excited to have found something that I'm still willing and able to drink after 4-hours. Here's hoping I still feel that way after 6 or 8 hours!

    Ultraman Florida 2016

    Posted by Stacy Martinez on 2nd Apr 2016

    Wow is all I can say. I have been racing for 6 years, in 2015 I signed up for Ultraman Florida a 321.6 mile triathlon. I knew I was going to need some spot on nutrition for such a long event. I found Tailwind through a fellow endurance runner friend. I have never felt so good as I have this year, I used it for all of my training and races in 2015. I of course used for my Ultraman race this February. Not once since I have been using Tailwind have I hit a wall or nutritionally bonked. I race and finish strong. I am not sponsored by Tailwind, nor do I receive any type of free items. This is an honest review of a product that works perfectly, tastes great and is easy to calculate amounts needed per event. Thanks Tailwind!!

    Successful 50K

    Posted by Caleb on 29th Feb 2016

    My wife and I started and finished our first trial 50K using tailwind. I had a bad experience with my first marathon back in December from heat (yes, in December - I know, right?) causing my electrolyte levels to drop. I knew going into the 50K that a solid nutrition plan would make or break the race. I had heard Tailwind mentioned in various ultra-marathon podcasts and figured we'd give it a shot. All the flavors are good, neither my wife or I had any digestive issues during the race. I'm happy to have a go-to solution for my electrolyte and caloric needs during those really long runs.

    Best I've Ever Felt

    Posted by Nick on 5th Jan 2016

    I tried this for the first (race) time in an trail ultra. It was a hot day in the mountains and I ran the first 47k and felt the best I have ever felt at that distance in a race. I then made the mistake of thinking I needed to add more calories. I ate a whole banana and almost threw up (in hind sight I should have) too many calories, too hot. I went threw a rough patch for a few hours as my stomach dealt with that and then got back to it using nothing but Tailwind till the end. Used it again for another trail ultra in the mountains, even hotter, I found that I needed less than the suggested amount for "endurance grunts," we are all different. I think this product works great and have stopped looking for anything else. Also nice to get a personalized note in the order. It's always nice to support the little guy (growing up fast). Thanks Tailwind

    It Works!

    Posted by Angie on 16th Nov 2015

    I tried Tailwind on my Tuesday night run and had my first 30K trail race a few days ago. I filled my hydration pack with it and thought if I needed anything else I would eat something from the aid stations. At the first station I ate one potato chip. Mostly out of habit of seeing food and eating it! That's all I had the entire run other than the Tailwind. I couldn't believe it! I felt good right up to the finish and wasn't hungry. I can't wait to use this in my next marathon and 52K coming up. It's amazing! I always relied on GU and with this I feel like I stay even instead of highs and lows through the entire run. Glad I found you!
