  1. Nice Change

    Posted by David on 21st Apr 2014

    Tasty, and so far so good on the long runs (30+ miles). Flavor is good, and definitely have noticed less need to be eating other supplements. A little on the sweet side, but haven't had the stomach issues I've had with other products, so all in all recommend giving it a shot.

  2. Caffeinated Tailwind for 8 hours

    Posted by Steve on 9th Apr 2014

    A few weeks ago mountain biked on my training hills 53 miles, 6:58 riding time, 8 hours total (yakked it up with everyone on the hill, all 6 of them), 11,500' gain. This last Sat (4.5.2014) rode the VQ - 54 miles, 7:50 riding time, 8:02 total time (breaks; top off Camelbak with TW, pee, top off Camelbak with TW), 11,300'. Both rides I used Caffeinated Tailwind. No gels, no bars. Sure I started to feel a little tired on each last uphill, but was able to push hard - super hard on level and downhill. And my stomach had no ill effects. Felt fine. Tailwind was my only carbo and electrolye food stuff. It works. Real simple; it works. And on the last resupply break, took me a minute or maybe 2 to top off with premixed TW, while saw someone else who was pouring one powder into a water bottle, putting gel in one jersey pocket, bars going in another pocket. I was in and out before he finished. Steve

  3. Keeps you strong for training

    Posted by David on 7th Apr 2014

    I started using tailwind a few weeks ago after a friend let me try some on a long training run. Since receiving my own, I have used tailwind for every run over 1 hour. I have found that one bottle with just under 2 scoops keeps me going for about two hours. I like the taste and most importantly I can tell a noticeable difference in my stamina...with nothing else! No gels, chews, or food. Just tailwind. I am looking forward to see how it works on even longer runs. So far its been great for the 3 to 4 hour range.

  4. PRs All Around at American River 50 Mile Endurance Run!

    Posted by Laura on 7th Apr 2014

    My husband and I took the Tailwind Challenge for our 50 mile foot race and couldn't be happier with the results. The Raspberry Buzz definitely gave me an energy kick at mile 29. It was just what I needed to get through the tough miles (miles 33-38) before I got my second wind at mile 40. My husband was having stomach issues for the first 30 miles and Tailwind was one of the only things he could keep down. It was his main source of fuel for the whole 50 miles and he started feeling better after 30 miles and picked it up at the end. We will definitely be using Tailwind again!

  5. Endurance Fuel

    Posted by Robert Riesenberger on 21st Feb 2014

    After a recomendationfrom a relative, I used this last year at the LT100 Mountain bike race. I actually used it as one of my 2 fuels and planned it more as a backup. It turns out, I pretty much just used Tailwind and made it through the race feeling good ( relatively speaking). I just got a bunch more for this season!

  6. Caffeinated Endurance Fuel absolutely works!

    Posted by Steve on 18th Feb 2014

    After training, and going through 3 bags of Caffeinated TW (2 beta and 1 more recently) I am more than pleased to continue with the use of this product. It is my sole, no nonsense, hydration product. After multiple rides of 5+ hours 8,500' each it has not failed me in any way. Note; in other review I noted my hr seemed to be higher and thought the product was sweet. Now feel Caffeinated TW is not too sweet (change in production version?) and really like the taste. My hr seems lower (i.e. 'normal', not elevated), but also could be from intense training and actually being in better shape.

  7. Great product for endurance athletes

    Posted by Unknown on 17th Feb 2014

    great product - good ingredients - and i don't get tired of the taste like with other sweet drinks - great balance

  8. Very good so far!

    Posted by Brian on 16th Feb 2014

    I gave this 4 stars only because I have only been using Tailwind for a few weeks. However, so far I have to say I am impressed with the product. The first time I used Tailwind I ran for five hours and only drank the product exactly the way they say to mix it. I can not lie, my mind told me to eat, but my body did not need it. After five hours on the trail I was still going strong. Maybe after a few more runs I will give it a fifth star, but it seems to work well for me.

  9. Finally... something that lasts for the longer runs AND tastes good!

    Posted by LN on 6th Feb 2014

    I found out about Tailwind through a friend and I'm not one to stray from my "go to" products. I've done a bunch of marathons and a few ultras, always struggling with GI issues. Having to be gluten free has added another challenge to my dietary restrictions.

    After the first trial of Tailwind on a long training run, I was hooked! This stuff is awesome! It's not overpowering in taste and it mixes so well with water. It's my main fuel source for sure now!

    The orange flavor is the way to go... I can drink that all day on my long runs and never tire of the flavor or the feel of the fluids when I'm taking them in. It gives you the stuff you need to keep going without weighing you down with crazy carbs or a lingering aftertaste!

    Tailwind will be my life line for my first 100-miler in April!!

  10. Done searching...I found it.

    Posted by Nate on 13th Jan 2014

    Started using Tailwind in early November '13 after running a sluggish 10:40 at a local 50 due to GI issues. Had 2 DNF's in 2013 due to GI and was just pissed off that nothing was working. Fed up, I asked the second place runner what he was using and he said Tailwind and went on to sing the praises. I was like, ok another powder based fanboy but figured what the hell so bought a pouch and went out for a long run a few days later. Safe to say that I was converted immediately and have been religiously using it since for any runs over 60 min. I use the Orange Mandarin flavor and not only does it taste GOOD but it WORKS and you get ridiculous carbs from one bottle. I have toyed with the mixing and I do just under 2 1/2 scoops for 22 oz and for a 5 hour run 2 bottles is just perfect. Can't wait to try Tailwind at my first 100 of 2014 (Saltflats) and then I have a few more Ultras this year where I expect to be using it as well. One other thing I would add is that, after being a powder user of other brands for a while now, it is very refreshing to be able to mix a bottle and a) not end up with a sticky counter, bottle and fingers and b) actually WATCH the powder dissolve instead of just clumping and looking disgusting. I would also add that I have not spent a single dollar on gels since October and my plan for 2014 for all of my races/long runs is simply Tailwind and if I need something to chew on then maybe a PBJ or something but primarily Tailwind.

  11. This is the best for Mountaineering/Splitboarding

    Posted by Patrick Moore on 9th Dec 2013

    I purchased the Tailwind challenge after trying a few pounds of Tailwind (Orange flavor), and will use it to train over the Winter for various splitboard climbs throughout the current and upcoming season. While not ultramarathoning, skinning up 10,000 feet over the course of a day, with a heavy pack, has its own challenges and is a good use for Tailwind. So far, Tailwind has worked, for me, very well, and has allowed me to keep going through wind and snow.
    I am grateful to use and endurance drink that doesn't have a laxative effect, like all the other commonly available ones that I have tried have had on me. I also get headaches from those drinks that have artificial sweeteners, and Tailwind doesn't have those.
    A big plus is that the Orange and the Lemon taste really good, though not overpowering.

  12. Search is over

    Posted by Dan Kerns on 9th Nov 2013

    After finishing 39 marathons and only walking away from a handful without having severe nausea, I used Tailwind as my only energy and hydration source for the Mt Nebo and St George marathons with positive results. I took a 2 scoop 20oz pre-race drink and consumed three 2 scoop 20oz (60oz total) water bottles during the run. Had no usual stomach shutdown issues and was able to eat a post-race meal within an hour. Equal to overcoming the nausea issue is the confidence at mile 20 to be able to continue racing without fear of the stomach shutting down. I've recommended to several friends who have also experienced positive results.

  13. Not a sole solution for workouts over 6 hours.

    Posted by Norm Hageman on 4th Nov 2013

    Tailwind works well for century bike rides, but falls short for ultra rides. I find it hard to keep drinking after 6 to 8 hours of riding. I needed to use a combination of Tailwind, chocolate milk, Gu, and solid food to get the calories in me. Then you have the typical switch to the body craving straight water in addition to the above. Thus, I had to switch over to using Endurolytes and Legs tablets to get my electrolites.

    Tailwind is a good product, but it is overselling when they say it is the sole solution to your calorie and hydration needs.

    [Tailwind Response]: Thanks for your feedback, and I'm sorry to hear that Tailwind did not work for you as a sole fuel source. I've followed up with an email so we can better understand how you used Tailwind, and hopefully help you dial it in better. It just may be that the taste is not right for you, and as a result you drank less which means less calories/electrolytes. We look forward to hearing from you. Thanks!

  14. Best Nutrition I Have Found To Date

    Posted by Christopher Wiley on 19th Oct 2013

    Tailwind is the only product I have used that supplies both my nutritional needs while running ultras...calories and electrolytes. I have tried gels, shot blocks, and other nutrition which shall remain nameless but the manufacturer is a tool...haha. Nothing has worked until now. And it is so much simpler than trying to remember calories and S-caps. Wish I had found this so much sooner. The company is a great example of customer service, excellent product and personalization.

  15. Once again Tailwind delivers!

    Posted by Jeremy Bonnett on 3rd Oct 2013

    Still quite impressed by Tailwind Nutrition and the positive effects it has had over the Summer on performance. I continue to test the limits of what my body can handle, not just in ultra-runs but in adventurous hike/run events and Tailwind holds true to it's claims every time!

  16. Best yet

    Posted by Bert on 30th Sep 2013

    I've been using Tailwind exclusively for the past 2 months. I used it in the Wasatch 100 start to finish and lots of other endurance runs, races and rides. It's awesome! It's way easier on my stomach for some reason than all of the other similar products I've used.

    I have all of the flavors and half the time I can't remember what I already have left over in my bottles or bladder. I mix flavors all the time and it tastes fine. Also it doesn't go rancid if left in bottles overnight or multiple days which sure is nice.

  17. tastes great even warm

    Posted by M Thrasher on 24th Sep 2013

    Two concerns when ordering this 1)does it foam 2) how does it taste warm. I generally run with a hand held on anything over 50k so when the miles get slow, the liquid is going to heat up. This not only does not foam but also maintains a good taste! Love the product and will keep ordering after my challenge bags run out. Could not be happier with the find.

  18. Tailwind on Ironman Tahoe

    Posted by Mike on 24th Sep 2013

    I used Tailwind on Ironman Tahoe and it worked great! Really paid off being able to get down the cals needed on the bike in order to have a great run. It was easy on my stomach and was easy going down. I would recommend TW to runners and triathletes both.

  19. Best nutrition out there!

    Posted by Dave Walston on 19th Sep 2013

    I purchased my first run of Tailwind late in the winter to get ready for my spring mountain biking and experiment with while snowshoeing. I was very happy with the energy it produced and happy to not have to worry about buying additional food for 1-2 hour workouts or rides. I have sustained myself through a season of races and riding with only Tailwind as my nutrition source. I did supplement it with clif bars on rides over 30 miles just for the extra calories. The Tailwind product never made me feel too full or tasted too sugary in my mouth. I love it. Thank you.

  20. Tailwind has given me that boost!

    Posted by J Stasulli (Ft Hood, TX) on 19th Aug 2013

    I was introduced to Tailwind by a running partner! Prior to using Tailwind I was hitting various products, gels, blocks, etc. trying to find the correct combination to prevent me from bonking on my long trail runs. Since Tailwind, I have had absolutely no problems. Since using Tailwind I have ditched the gels and blocks and running solely with my Tailwind!

    I feel strong, feel good, and know that I have what I need for the next step!

    As was done for me, I share sample packages with fellow runners so they too can feel the difference and take their training to the endurance training to the next level! Now I need more sample packs!!!!

  21. Awesome Product!!!

    Posted by Frank on 10th Jul 2013

    I was introduced to Tailwind through a fellow ultrarunner. I took the challenge based on them backing their product up with an offer to pay my next race entry if I wasn't satisified. I figured it had to be pretty good and I really had nothing to lose. Well I am happy to say I am totally blown away and will gladly be paying my own entry fee. My typical fueling strategy was as follows: carb drink only first 2 hours, gel every 30 to 60 minutes, electrolyte cap every 45 minutes and then switch to carb/protein drink after two hours. My first real test was yesterday. My run lasted about 2 hrs 7 min in the low 80's with high humidity. I used @ 200 cal per hour of Tailwind and nothing else and felt amazing! Tastes great with absolutely no after taste. I have successfully replaced 4 products with one single product. My next 50 miler is in November and I can't wait to see how the training and the race goes now that I have Tailwind!

  22. It's all you need

    Posted by Albert on 8th Jul 2013

    I've used this for the past year or so. I don't take any other products with me to eat, and I feel hydrated, and with plenty of energy throughout the ride. I average 50 miles a day and have easy recovery as well.
    I did us it on a 32 mi walk as well, and over 9hours it performed great!

  23. Simple and efficient!

    Posted by Jeremy Bonnett on 17th Jun 2013

    I joined the Tailwind Challenge and have used the product for over a month now on numerous training runs and races. After a 50k and 50 mile race using only Tailwind I can honestly say the product has surprised and excited me like no other product on the market.

    While at a 50k event with Tailwind I was still in the "ultra-mindset" of eating during the race. It was the first time I'd used it for a long duration and I consumed dates, watermelon, and a few nuts along with the Tailwind. I had stomach issues and contacted Jenny with customer service. She was incredibly nice and knowledgeable and ensured me Tailwind was all I needed and my system simple had too much sugar in it with the added food intake. She was right. Two races later and no issues at all. No bloating, no fatigue, no cramping, and feeling lightweight and strong the whole way!

    Tailwind is definitely top on my list of must-haves for long runs and races in the future!

  24. This is the bomb

    Posted by Richard A on 14th Jun 2013

    OK, so this is going to be kinda detailed: On Sunday I did a tough 6.5 hour mountain trail run (5,500' of gain and loss) relying exclusively on Tailwind Berry and Mandarin Orange for nutrition, hydration and electrolyte replacement. At about 5'-7" and a 118 pounds I'm not a very big runner, so I usually shoot for about 180 to 200 calories per hour, and around 14 ounces of water per hour (more when hot, it was cool on Sunday (high fifties to low sixties)). I expect that some may think that insufficient, but the number is based on Tim Noakes' latest book, "Waterlogged", (a must read, by the way for anyone participating in endurance activities), and works well for me. I mixed ~2 scoops of TW per 14 ounces of water into my hydration reservoir (a little more concentrated than recommended, but I was experimenting after all) and took a 2 ounce (or so) sip every 8 minutes. I felt a little flat for the first hour, but after a little more time my energy levels rebounded and I reached a good, constant state that lasted until the end of the day. I obviously fatigued as the day wore on, but I never felt like I ran out of energy, I was never thirsty, never nauseated, and never felt bloated. Importantly, I also never felt hungry. I would say that TW provided a constant, even energy, with no ill effects. I didn't get tired of the taste, although I did switch to a 4 ounce "sip" every 16 minutes after about 3.5 hours. A further awesome result is that I felt really good after the run - no "depleted" feeling. I was ready to eat regular food right away, and felt better after this kind of effort than I usually do. Next time, I will drink more TW before starting out to try to avoid the flat first hour. All in all - a great first time out result! I'm sure I'll dial it in even better after a few more outings. At this point I'm really optimistic about TW being my all-in-one endurance nutrition solution going forward.

  25. Tailwind: the name says it all

    Posted by Coleman M on 12th Jun 2013

    Based on the recommendation of a friend (Karen F.), I used this product for a week prior and then during a 1/2 Ironman. The mix aided and sustained me throughout the day. I never felt depleted of energy the whole day. I intend to keep using it in preparation for a Full Ironman this summer. Love the product!
