  2. 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!!

  3. 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.

  4. 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

  5. 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!

  6. 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!

  7. 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!

  8. 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!!!

  9. 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!

  10. 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:


  11. 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

  12. 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.
