Excellent addition to ultramarathon nutrition
Wednesday, 26 October 2016  |  Brian

I used Tailwind to fuel a recent marathon in Budapest. I was pacing for a friend and wanted to see how effective Tailwind was as the only nutrition on a long run. I found it very easy to drink without any sickly taste or stomach problems, although I generally have no problems with gels in that regard. Tailwind was successful in fuelling the 4 hour run and will be a good addition to my nutrition during ultramarathons. I would not use it as my sole form of nutrition for an ultra, however I can see the benefits, especially later on when I struggle to take on solids/gels.

Great product!

Used Tailwind for my last Ironman (Ironman Wales) as my primary nutrition. I found it allowed me to reduce my gel requirements, whilst keeping my energy levels high and my sensitive upset stomach at bay.
Now training for an ultra marathon, and so far the product is doing its job perfectly.
Awesome customer service from the guys at Tailwin, and a really great product that tastes great and works!
Highly recommend trying Tailwind

'Something for nothing' - a generous gesture that is very much appreciated.

First class
Tuesday, 25 October 2016  |  Dan

It's hugely heartening when you discover a brand that meets (and exceeds) all it's own marketing hype. The flavours are great and so far the only thing letting me down is MY legs!

Spring in my step
Tuesday, 25 October 2016  |  Dan

Easy on the stomach; a great range of flavours and a first class service when ordering, means this is my product and drink of choice.

Squidgy happiness!

Really nice bottle. Easy on fill, easy to hold, very clever valve. Then when empty, squashes down to nearly nothing.

Tailwind 2 Serving Stickpacks
Monday, 24 October 2016  |  Helen

simple flavours and easy to use. Would be useful if came to narrow packets to place directly into the flask to dilute it.
Love it and will continue to use not that I have the ultra bug!

Don't understand how I managed to run without this before. Expensive purchase but last you a life time. Love it.

Soft Flak Review
Monday, 24 October 2016  |  Nigel

Absolutely superb product, much improved compared to the old hard flasks. Easy to handle, easy to drink from and they fit into the UD racevest pockets perfectly. I found the 500ml size perfect for the dilution of 1stick pack (200cal). Service and delivery was impeccable - as always! Thanks Mike

Great product
Sunday, 23 October 2016  |  Jamie

Tried Tailwind for the first time this weekend on a 21 mile training run. No gels, no snacks, no sweets needed. Felt fantastic all the way round. Will definitely be ordering more to be used on all my ultras. Just what I've been looking for.

Friday, 21 October 2016  |  Paul

Easy to order, received within 24 hours which is exceptional. And the product, tastes great, not too sweet and the important bit, does what it says on the tin - energises through the whole run, nothing else has come close. Personal message spells amazing customer service. I'll be back for sure.

They do their job admirably!
Friday, 21 October 2016  |  Conrad

I ordered these flasks in time for the Autumn 100. Previous flasks I had were difficult to unscrew tops and therefore an unwanted faff at race CP's. These Tailwind flasks presented no problems at all. A nice compact size, no leakage and ease of use all day. I recommend!

Moreover, a quick delivery and friendly note from Mike topped off the quality of service received. Thank you!

Excellent product and service
Friday, 21 October 2016  |  Rachel

Fantastic service, highly recommend. A lovely personal note in each order and a very unexpected email wishing me luck in my upcoming race. A very nice touch. Fab products too!

Wednesday, 19 October 2016  |  Luisa

Tailwind was recommended by a friend to try on our long runs (building up from 16miles). She kindly supplied and filled our bottles with the Tailwind stick packs. I found it really easy to take and it seemed to do the job! I have since bought my own supply and used it today on our 19 mile run. Again it was easy to stomach and it kept me going! Previously I was fatiguing after about 13 miles, however since taking tailwind my energy levels and endurance have been great. I'm Really happy so far, this is the best fuel for runners, by far!

Mandarin orange endurance fuel
Wednesday, 19 October 2016  |  Martin

Having tried the various flavours on offer I've gone for a multiserving of mandarin orange. Great taste without being too strong. Excellent product and all you need for the long runs

So far so great!
Wednesday, 19 October 2016  |  Ashley

Tried Tailwind for the very first time last weekend, the run was only about 10 miles so not long enough to properly vouch for the nutritional aspect, but despite that my first impressions were great.

I recently ran my first half marathon and have been finding that running 10+ miles I don't really hydrate enough. Last weekend I took out my new race vest with soft flasks (the same Hydrapak one that Tailwind sell) and filled one with water and one with water+Tailwind. Normally I wouldn't manage to drink 2 500ml bottles on a short 10 mile run but after 6 miles I'd already finished the first bottle with Tailwind. The Mandarin flavour was great, and I honestly don't know why but I found that it just seemed to sit better in my stomach than just drinking water. Luckily I'd brought another (Berry) sachet in my vest, so I added that to my second bottle and finished half of that off by the end of the run. Again, super easy to mix, great taste, went down really easily.

I'm just starting to build my distance from half marathon to full marathon over the coming months, and whilst I've tried a few brands of gel and not had any problems with them I really think I'm going to prefer taking Tailwind.

I'd also add that my delivery turned up really quickly, and I was lucky enough to get one of the free soft flasks too due to my order value. Now that I've tried these I highly recommend them.

If all continues to go well I suspect I'll be another long-term convert/customer.

Grand 2 Grand Ultra

Hi Rod/ Mike,
thanks for the support and especially the messages while I was out on the course. Some feedback which you are welcome to publish:
My experience using Tailwind in the Grand2Grand Ultra
On the strength of Mike Julien's experience of using Tailwind in a previous G2G and my dissatisfaction at alternatives in previous races I decided to use Tailwind for my running nutrition at this year's G2G race. My approach was to pre-prepare ziplock bags with 3 scoops each for every stage which I would decant into a single 750ml raidlight water bottle. I used the natural flavour for most stages and the caffeinated green tea for the last stage (last 3 stages on the long day) each day. I also supplemented with SCaps! electrolyte tablets as I know that I excrete a lot of salt and had a few small blocks of cheese to suppress any hunger pangs.
My approach worked brilliantly for me feeling strong with plenty of energy every day. I found that having 1 bottle of tailwind and another of plain water mean't that i didn't suffer palate fatigue except in the latter stages of the long day where i think that a greater use of "solid" food for some variety might make sense. I could probably have used only 2 - 2.5 scoops for each stage as I found that i didn't always drink the whole bottle and then adding another ziplock at the next checkpoint made it pretty strong. Mike's approach of taking the whole bag on the race and then decanting each night knowing the stage distances from your road book might make sense but i was concerned with carrying too much weight.
Overall I would highly recommend using tailwind for stage racing but be sure to test your approach in training.

Tailwind trial
Tuesday, 18 October 2016  |  Tony

Used for the first time on a 10 miler over the weekend and found it easy on the stomach. taste was good and the bonus is that I can eat solid food after the race . before on gels I always feel queasy after a run and cannot eat All in all things are looking very promising for Tailwind and will use it on a regular basis and have a happy gut.

Great product
Tuesday, 18 October 2016  |  Sophie

I have just started using Tailwind and trialed it at UTMB, I love the fact it is so easy to mix and taste great. I also am in love with the personalised card and my name on the bag .....it's the little things! Have yet to go completely TW so will do that in my next race and see how it goes.

Monday, 17 October 2016  |  Nathan

first time trying Tailwind so I opted for the 2 serving stick packs, great tasting and no stomach issues, going to be tough choice on what flavour to order on-going

Brilliant service
Monday, 17 October 2016  |  Ksenia

Good communication, instant delivery, brilliant product.

Sunday, 16 October 2016  |  Sarah

First half marathon completed this weekend. Used only tailwind and it was fantastic. Got round 3 minutes faster than expected, with absolutely no issues. Love the taste (lemon). Slightly salty, but I didn't mind that all. Definitely recommend

Great service, great product!
Sunday, 16 October 2016  |  Tina

Fast and friendly service, nothing was too much trouble. Great product that really works, tastes great too. Some products leave you feeling bloated with a funny taste in you mouth but this one didn't it was just perfect. I had the mutli pack to trial the products and all were great. Difficult to chose which one I preferred. Will definitely be ordering again soon. Highly recommended.

Super Service
Saturday, 15 October 2016  |  Jodie

Service is always fast and efficient, with an added personal touch. Product delivers exactly as promised. First time I've used the stick packs and they were really convenient. All flavours very palatable, too.

Brilliant service
Thursday, 13 October 2016  |  Jane

Can't recommend Tailwind enough. It's a great product in taste and performance. Nothing too much trouble when ordering. I had flavour change request, in a multistick order and it came just as I asked for.

Quick delivery great service
Thursday, 13 October 2016  |  Istvan

Service was perfect. Ordered the berry and raspberry buzz. Got here quick with a personalised TW card. My name on the bag was a nice touch as well. I have tried the berry so far in longer training and had energy until the end of session. It was easy on the stomach and I like the taste too. Still experimenting with concentration. I am running a 50k trail race in November and will be using TW. I will let you know how it went.

Green tea Sticks
Thursday, 13 October 2016  |  Ethan

Really can't recommend enough, next day delivered, really tasty product that's easy going on the stomach. Have yet to use it for a longer run but I'm sure it will be great. Also received a personalised little note to wish me good luck which I thought was a really nice touch. Thank you for th great product and service.

Simply the best supplement!
Thursday, 13 October 2016  |  Matt

I started using Tailwind through running tips on hydration etc from friends who had used the product before, and I have not used a better supplement than Tailwind. I've taken it for events such as Hope24, running 55 miles, the 32 mile Dartmoor Discovery and the Red RAT coastal of 20 miles. In each event Tailwind has kept me both hydrated and sustained, I can not recommend a better product. It is simply the best I've used in the years I have been running.

Perfect for the longer run
Wednesday, 12 October 2016  |  Nick

I've been using tailwind for a number of years now. Great for the sustained efforts. Figure out the concentration that works for you and then you are set. So much easier than other nutrition / hydration strategies. Would recommend!

Tastes Great and did the job!
Wednesday, 12 October 2016  |  Helen

Tailwind was recommended to me during a recent 50 mile Ultra so I thought I'd give it a try I'm so glad I did, I've just converted 2 running friends to it as well! I'm looking forward to testing it out on my next marathon distance in November Thank you

Tuesday, 11 October 2016  |  Matthew

My colleagues are concerned about the apparent change in behaviour. My students are puzzled but they're going along with it. As a lead teacher in a school striving to succeed, I am trialing tailwind in the most testing of endurance climates. And early signs are promising. Using an unknowing member of my team as part of my random control testing, they are losing their bounce by the day (we're now in October and the current measure is 'intermittently grumpy sod'), yet I'm holding form (current measure = dancing in your face). Arguably still early days but I have hope and I have yet more palletable flavours to try. Well done Tailwind, I'm taking these to the trail.

Such a brilliant service
Monday, 10 October 2016  |  DAN

Wow X ordered my green tea and it was here so quickly, packaged with love including a lovely note and my name on the product bags. Little touches like that go along way to telling what a great outfit this is.

Nice one.
Monday, 10 October 2016  |  Dan

Well this is the first time I've used tailwind after been told about them on a ultra marathon. I must say they mix really well, they don't taste powdery and the flavours are nice. I will be telling others about them.

Won't use anything else
Monday, 10 October 2016  |  Mark

Started using Tailwind for 2016 season and seen improved results consistently. Perfect for going long. Ironman races are hard enough and I don't miss that sick feeling you get from sucking down numerous gels. Using the TW I feel strong throughout. My favourite flavour is the mandarin orange, refreshing and pleasant to drink all day whilst taking care of business. On the customer service side it's better than perfect, fast hassle free delivery, easy website and even the personal touch, hand written good luck cards before major races. Can't be faulted

401 Marathon
Friday, 7 October 2016  |  Pat

I used this whilst running Marathon 401 with Ben Smith. It worked for me, no tummy upsets & kept me hydrated. I will continue to use these, although may be a while before I run another marathon! The pack is way to halve & can put the other half in your bag/pocket if you need to use more.

Does what i was told it would !!
Friday, 7 October 2016  |  Stefan

Used for the first time on a 50 mile cycle and provided the energy I needed and no gut bombs!
will use again

Something that works?
Thursday, 6 October 2016  |  Lisa

I have a number of dietary challenges that have left me unable to take any of the commercially available gels or hydration products. I ordered the sample pack to test its suitability; it arrived promptly with a personal message which is a great if quirky extra. I've started to try the sachets s d so far, so great. I just need to learn my needs and to keep running.

Superb Energy Source
Thursday, 6 October 2016  |  Peter

A great source of constant energy through drinking water and I definitely prefer this product to gels. Would definitely recommend to others and I've found it an invaluable part of my running kit for hill marathons.

Really impressed so far!
Wednesday, 5 October 2016  |  Derek

Prior to trying Tailwind I had been combining water, electrolytes and energy products with varying degtees of success. I have to say I'm a bit of a convert now to this product as it removes a lot of hassles from managing your intakes! It's also very easy to drink and doesn't give my overly sensitive stomach any grief! Definitely worth trying!

Good stuff
Wednesday, 5 October 2016  |  Gair

Done 14 miles today, had the berry. Good flavour not overpowering and no issues while I was running . Used the green tea sachet last week again great flavour and the three other people who tried it agreed.

Great service, great taste
Wednesday, 5 October 2016  |  Julie

Bought a sample pack after trying a friend's - tasted lovely without being too sweet & sticky, got through a 17 mile fell race without any crashes or digestive issues. Great personal service too - appreciated the handwritten note with my (very speedy) delivery. All good

Great product, great service.
Wednesday, 5 October 2016  |  Keith

I use Tailwind on all my long training runs and marathons. It is an excellent product. No ill effects, easy to digest and it delivers really good results. It's the only nutrition product I would use. Service is superb.

Nausea- free Running with Tailwind
Wednesday, 5 October 2016  |  Peter

For several years I have not been able to eat after events and have always been unable to eat or drink after 30miles or so into an ultra.
All the different eating/drinking strategies I had tried made no significant difference - until I tried Tailwind on the Heart of England Forest Marathon last weekend.
The result was quite remarkable.
Taking only 1.5 litres of Tailwind I experienced none of my usual symptoms which allowed me to focus solely on the run.
Despite worse weather conditions than last years running of this event I even finished in a faster time, and ate like a horse at the end!

Finally, happy guts!
Wednesday, 5 October 2016  |  Nikolas

After trying Tailwind on training runs I've just finished my latest ultra using it, supplemented with little sips of honey for a bit of variety and an energy boost. Definitely the most palatable and digestible race nutrition I've ever tried. I happily kept taking it all through the race with no digestion issues or rejection, unlike gels where I tend to get sick after about 3 hours and can't face eating, leading to inevitable lows. Tailwind will be the mainstay of my race nutrition from now on.

Best supplements I've tried
Wednesday, 5 October 2016  |  Daniel

I've done now 4 races (30K, 50K & 100K) on just tailwind. Didn't take one gel or anything else for that matter. It does it's job perfect, if you drink it as recommended there is really no need for anything else.
The taste is much better that expected. The Lemon goes down like a charm, green tea has a little more "artificial" taste to it but didn't have any stomach problems whatsoever. Still didn't notice the difference in the added amounts of caffeine which is good.
The customer service is top notch. It feels like you're buying of a friend, not a company. Shipping was fast and cheap for outside the UK. Will definitely be buying again.

Tuesday, 4 October 2016  |  Amy

Great product, so nice to be able to ditch the gels, Tailwind gives you all you need. Great customer relations too, I received a lovely note with my order and a lovely email wishing me well in my marathon. Can't recommend these guys enough. Brilliant

What PBs are made of!
Tuesday, 4 October 2016  |  Lisa

Ok, so take the title of this with a pinch of salt if you wish but here's my experience!

I have used Tailwind on ultras, alongside food before and have found it has kept me nice and hydrated. I like the fact that it's a sneaky way of getting more calories in. In the ultras, I've used tailwind on, I've had good races & have felt strong.

On Sunday, I used tailwind for the first time on a road marathon at Chester, alongside gels and I got a PB...I've been trying for a sub 4 for 6 years and finally got it! Make of that what you will! I would definitely rate this product and will use it for training and races in future. Thanks Mike and Team!

A new kind of nutrition
Monday, 3 October 2016  |  Jonathan

I am enjoying this new form of hydration I've used them on two long runs now and certainly better than gels. Thanks to my ladies at our running club who recommended tailwind to me. I also loved the personal hand written note that came with my pack. I will order again. Thank you

Excellent service

Tailwind PB Give it a try
Monday, 3 October 2016  |  Marion

Slightly salty taste but after a few sips didnt even notice it, very light on the stomach. I ran a PB in my Marathon by almost 30mins was it the Tailwind??? Nice personal service too with a nice little message. Thanks
