Tailwind questions

The useful details before you choose

What is in one Tailwind Endurance Fuel stick?

One current stick pack is a measured two-serving portion of Endurance Fuel. Check the exact pack supplied for its current net weight, mixing instructions, ingredients and nutrition.

Should I buy a box or a single stick?

Choose a box for regular training, travel or events. Choose a single stick if you want to test a flavour or need one measured pack for a session.

How should I mix a Tailwind stick pack?

Follow the instructions on the exact pack. Tailwind's current guidance is to mix a stick pack with water and sip it over the planned period, adjusting only after practising in training.

Which stick-pack flavours contain caffeine?

Raspberry and Tropical Endurance Fuel contain caffeine. The other current Endurance Fuel flavours shown here are caffeine-free. Check the selected option and pack before use.

Are the box and single formats the same formula?

The selector keeps matching Endurance Fuel flavours together so you can choose the pack format you need. Always check the exact option, ingredients and pack information supplied before buying.

Can I use Tailwind alongside gels or food?

Some athletes use Endurance Fuel as their main carbohydrate and electrolyte source, while others combine it with food, gels, bars or chews. Practise the complete plan and avoid unintentionally doubling up.

Description and product details

Tailwind delivery & packaging update

As Tailwind stock gradually returns to the UK, some deliveries are taking a little longer than usual. Boxes and pouches may differ from our usual packaging, but the contents remain the same. Thanks for bearing with us while supplies get back up to speed.

Tailwind Endurance Fuel is a carbohydrate-and-electrolyte drink mix for longer training and events. These measured stick packs are available as 12-stick boxes or individual sticks where that exact flavour is offered.

Mix one stick into 590–710ml of water and sip over about an hour. One stick contains the same measured amount as two level scoops from a pouch: 50g carbohydrate, 200 kcal and 620mg sodium. Raspberry Buzz and Tropical Buzz contain 70mg caffeine per stick.

Choose a 12-stick box for measured packs on the move or at events, or a single stick to test a flavour before buying a pouch or box.

Practise the complete drink and fuel plan in training and check the exact selected pack for its current ingredients, nutrition and allergen information.

Caffeinated flavours are not recommended for children or during pregnancy.

Tailwind Endurance Fuel is vegan and made without gluten, soy or dairy ingredients. Check the exact pack if you have an allergy or intolerance.

Tailwind and the BEST customer service ever!

Could not be happier, Tony pulled out all the stops for this order. The first tracked order Royal Mail seemed to loose at Southampton Mail sorting office. Tony could see straight away the problem, and rectified it straight away at fantastic speed.
Great communication, always kept in the loop and everything is perfect. Without a shadow of doubt, the best customer service ever!
I can't rate Ready Sweat Go high enough, a fantastic company, friendly and faultless commitment to the customer. Thank you Tony, I shall be ordering again very soon!

Hello Ali and thanks for taking the time to share your wonderful feedback!

What can we say? Sometimes things don't go to plan and it's really unfortunate. But we've been there, and know that it can cause great stress (probably when it's the last thing you need!), especially before an event. We're delighted we got it sorted for you.

Your kind words mean a lot, our customers mean everything to us.

We look forward to welcoming you back!

Keep moving!

What a great taste, very easy to drink not like other drinks, felt really great doing an off road ride,more enjoyable than plain water. Definitely will be buying again.

Thanks for taking the time to share your feedback Glyn!

We agree 100% on the Dauwaltermelon, it's strikes a great balance of flavour vs drinkability over a long period of time.

Loving the Fat Bike pic, some rig!!!

Stay strong, Team RSG

Glad they’re back!

First picked these up in the stick pack for my summer trail ultra in the Cotswolds. Loved how they were not too sweet or heavy on the stomach. Just a nice at mile 6 as they were at 60. Really glad to see them back in stock and now in the bigger bag.

Hi John,

Thank you for taking the time to leave such a positive review. We're thrilled to hear that you enjoyed it during your summer trail ultra and that it held up well throughout the race. We're excited to have them back and in the bigger bags, for added value. Keep fueling those miles and happy trails! :)

Really impressed with Tailwind

Really impressed with Tailwind. It was recommended by friends who’ve competed ultras and Ironman events for my first 50k ultra this Sept. Big positives for me (1) very subtle taste (2) sachet format is perfect as I can take them in my hydration vest and top up either water at checkpoints and (3) so far it’s proved gentle in my stomach on long runs.

So great product and great service from ReadySweatGo.

Hi Paul,

Thanks so much for this level of detail in your review. Congrats on your first ultra thats some effort! And we completely agree the stick packs are perfect for that job!

We hope to welcome you back, to fuel your next adventure!

Keep moving, Team RSG

Best fuel I've ever used

I'm just back from running the Riga Marathon and Tailwind was the only fuel I used for the race. I've never enjoyed using gels/chews as my fuel and they typically cause stomach issues mid-race for me. Tailwind was the perfect solution, providing me with everything I needed for the race in just my two water pouches in my vest - dissolved double concentrate to get me through the 3 hours of exercise. Will be the only fuel I use going forward for endurance events!

Thanks for your kind review Ben!

That sounds like a solid strategy, especially if you don't get along with gels. Well done on your marathon too, solid!

Keep moving,

Team RSG

Perfect for marathon training

Training for Manchester marathon (my 1st marathon!) and someone recommended these - it's honestly been night and day. I was barely able to run 30km without them (exhausted, lots of pain) and now can run 30km+ and still have energy left at the end! Would highly recommend for anyone doing long runs!!!

Hello Jessica and thanks for taking the time to share your feedback!

We're delighted to hear about the effect the Tailwind had on your long runs! Doing exactly what it says on the tin (packet).

We hope you come back to Ready Sweat Go when you need a top up.

Thanks again and keep moving,

Best Fuel Out There

I am currently training for a marathon and after looking gor recommendations online i found Tailwind and it has been a game changer. My runs feel easier and with it being an all in one i dont need to worry about carrying or consuming anything else. It tastes really good too, not sharp or bitter.

Hi Joshua,

This is an excellent review, thank you so much. We couldn't agree more about the Raspberry Tailwind!

We look forward to welcoming you back, keep moving,

Altitude with attitude - Fuelled by Tailwind

I had been sceptical of going it alone on endurance ultras without a bag full of sweets, sandwiches and chocolate bars. How could nutrition drinks compete with the need to eat, despite the desire to reduce the carry load. But having delved int the world of Tailwind, firstly as a trial and then in earnest at recent UTS I can confirm that all scepticism has dissolved. The sense of freedom and the refreshing taste of the mixes have become a settling and comforting part of my long runs. The phrase 'don't leave home without them' (used in an advertisement, fadΓ³ fadΓ³ [long ago]) has currency here too.

I will be ordering more very soon.
