  1. Oh Tailwind, How I love Thee 5 Star Review

    (Submitted on 23rd Dec 2016)

    Adapted from a more famous poem of a similar name.

    How do I love thee? Let me count the ways.
    I love thee to the depth and breadth and height
    My sore legs will let me reach
    But my fuel tank is never empty.
    I love thee to the level of everyday's
    Most basic fueling need, by sun and headlamp.
    I love thee freely, as I strive for medals;
    I love thee purely, as I turn from DNFs.
    I love thee with a passion put to use
    In my old shorts, and with my new camelbak.
    I love thee with a love I seemed to lose
    As the miles add up, --- I love thee with the breath,
    Smiles, tears, of all my races! --- and, if God choose,
    I shall but love thee better after I finish.

  2. Absolutely Fantastic! 5 Star Review

    (Submitted 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!

  3. Too good not to try it 5 Star Review

    (Submitted 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!

  4. Great endurance nutrition. 5 Star Review

    (Submitted 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!

  5. Still testing, but so excited 5 Star Review

    (Submitted 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!

  6. best ultra nutrition PERIOD! 5 Star Review

    (Submitted on 19th May 2016)

  7. Ultraman Florida 2016 5 Star Review

    (Submitted 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!!

  8. Successful 50K 5 Star Review

    (Submitted 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.

  9. Best I've Ever Felt 5 Star Review

    (Submitted 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

  10. It Works! 5 Star Review

    (Submitted 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!

  11. Stop trying to find an equal... 5 Star Review

    (Submitted on 29th Sep 2015)

    I tried Tailwind about two years ago for the first time. It actually exceeded my expectations as far as flavor and performance. I'm not a fan of ordering online so I actually looked for comparable powders at my local bike shop. I tried numerous products from Hammer, Skratch, Gu, etc. with no success. They all either tasted funky, were just plain odd (Gu?) or didn't do the actual job, which is to keep from bonking or feeling hungry on the bike. I regularly spend anywhere from 2-hr. to 6-hrs. on the saddle and all I use is Tailwind. I just wish my local bike shop carried it!

  12. First 50 miler = a success with Tailwind! 5 Star Review

    (Submitted on 2nd Sep 2015)

    I purchased tailwind for the first time a few weeks before my first 50 mile race. I've always struggled with getting my nutrition right in my past marathons and 50ks. First, the customer service was awesome, I received a personalized email before the race from someone at Tailwind asking if I had questions and wishing me luck. I ended up running the best race of my life. I didn't use anything else besides tailwind. I felt great after the race too, but better than I usually do after an ultra! I can't wait to continue to use Tailwind as I get ready for my first 100!

  13. Leadville 100 5 Star Review

    (Submitted on 29th Aug 2015)

    I've trained with Tailwind since March with the goal to tackle Leadville Trail 100 this summer. I have nothing but good words to say about Tailwind. It really worked for me and allowed me to finish many races including Leadville. (Big accomplishment since I am a flat lander!) During the 100, I just used this product and occasionally had some cups of Coke. No solid foods or electrolyte tabs needed. Thank you for this awesome product! I am a big fan and will be using Tailwind for all my future races!!!

  14. R2R2R - Tailwind saved my tail! 5 Star Review

    (Submitted on 21st Aug 2015)

    A group of us did a R2R2R run/hike at the Grand Canyon back in May. On our final ascent, we had been awake for 26+ hours and were all very fatigued - not the best situation to be in with steep drop offs just steps off the trail. I pulled out the rest of my bag of the Caffeinated Endurance Fuel and mixed us each up a bottle. It perked us right up and gave us the energy we needed to get the thing finished. Tailwind definitely saved the day!

  15. Tailwind put to the test on the Mt. Whitney Trail 5 Star Review

    (Submitted on 16th Jun 2015)

    I took the Tailwind Challenge, for the upcoming TRT100 miler in July.
    I had some questions after using it for the first time, and within an hour of emailing customer service, I received a very thorough response, and each of my questions was answered perfectly - and, the customer service rep gave me some suggestions that I immediately put to use.

    I tried out the Tailwind on a 27 mile run on the Mt. Whitney Trail last weekend. I also shared it with a couple girlfriends - we all experienced the same result- when we started to feel depleted, climbing in altitude, we took more Tailwind, and our symptoms eased. So far, it has passed the test! Here's a post from my blog on the trip:


  16. endurance fuel 4 Star Review

    (Submitted on 27th May 2015)

    Very happy with the level of nutrition and performance though my rides
    I bring a dry mix with me and just add water
    could not be any easier

  17. Problem Solved. 5 Star Review

    (Submitted on 20th May 2015)

    I have waited a bit to write my review, I wanted to try this out in various training conditions and distances.

    In the past I have struggled with consuming nutrition/electrolytes that wouldn't have an adverse affect on my system. Let's be honest, who wants to end up with gut distress (read I need a bathroom NOW) at any point in a training run or race? I also struggled with heartburn issues from fuel and electrolyte sources. Often I would forego consuming electrolytes and just focus on nutrition and hydration. BAD idea. I am amazed at how much difference it makes to keep your body well supplied with electrolytes.

    I have used Tailwind on short hour long runs all the way up to marathon distance runs. I am in training for a 100 mile trail ultra, so mileage is only going up from here! I've used it in hot humid conditions, mild conditions, and cool conditions. I will say that in the hotter humid conditions it is wise to dilute the mix a little more, but it still works fantasticly.

    I am happy to report that Tailwind holds up to it's promise, and it's truly ALL you need. Yes, I was skeptical on my first long run, but I put complete faith in it, and it held up extremely well. I love that I can mix this up in my hydration pack and I don't need to bring anything else with me. I can easily sip it as I move along the trail, no worries about face planting while trying to eat additional nutrition.

    I used to be prone to horrible foot/leg/body cramps both during runs and post run. Since using the Tailwind products, these have vanished! I'm so glad I decided to take the Tailwind challenge!!

    The flavors are awesome, I ordered the Lemon, Mandarin Orange, caffinated Raspberry, and the Naked version. I love them all. They are light in flavor, mix easily, and easy to digest. Bottom line, this product is awesome. Order it now.
