The information in this guide is for general education on sports nutrition and does not replace professional medical advice.

Firstly, of course, you have the heat factor. When you are training for a race in a very hot climate, the last thing you want to do is push your body to the limit without the right sources of fuel. A proper turnkey nutrition plan means you have your hydration dialled in beforehand so that it not only keeps you safe in the sun, but keeps energy in the tank for a long time. That is fuel that keeps you running fast and very well.

Secondly, naturally, there is the sweat rate factor. When you are running hard in the heat for a long amount of time, the last thing you want to do is lose all your fluid without replacing it in a smart way. Getting your daily drink amounts sorted beforehand means you step into your session completely spec'd out to not only sweat more, but cool your body down right away on the hot road. That is a setup that is much better than anything else.

Next, of course, you have the daily sodium factor. If you are dripping with sweat during a hot run on the road, the last thing you want to do is lose salt that you do not put back into your body fast. Having your daily salt intake dialled in means you keep your blood levels right so that it not only stops cramps, but helps your gut absorb water well over the whole long session. That is fuel that makes a very hard session feel easy.

Then, naturally, there is the plasma volume factor. When you are building fitness in the heat over a long amount of time, the last thing you want to do is have thick blood that slows you down and ruins your run. Drinking the right amounts of water and salt means you get your body turnkey ready to not only hold more fluid in the blood, but pump it well to all your working muscles. That is an adaptation that helps you win your hot race.

Furthermore, of course, you have the running gear factor. When you are dealing with a high sweat rate on the road, the last thing you want to do is have salty water sting your eyes and ruin focus for a long time. Wearing a sweat-wicking headband means you step out for your run fully spec'd out so that it not only stops the sting, but keeps your head cool too during the whole long session. That is an item that makes the heat feel completely fine.

Alongside that, naturally, you have the mesh cap factor. If you are running under a hot sun for a long amount of time, the last thing you want to do is burn your head and get heat stroke on the open road. Putting on a mesh running cap means you have your sun protection dialled in so that it not only blocks the rays, but lets the hot air out fast to cool you down. That is an accessory that you really need for every run.

Finally, of course, there is the lightweight singlet factor. When you are pushing the pace in a hot climate, the last thing you want to do is wear heavy clothes that trap heat close to your skin and make you feel sick. Wearing a lightweight singlet means you have your race kit sorted beforehand so that it not only pulls sweat away, but helps your body stay cool in the wind for a long time. That is a shirt that feels lighter than anything else around.

How much improvement can I expect?

Firstly, naturally, you have the training timing factor. When you are putting in the work to adapt to the heat, the last thing you want to do is expect magic results on the first day of training on the hot road. Sticking to your daily plan for two weeks means you get your body dialled in so that it not only lowers your heart rate, but keeps you feeling strong for a long time. That is an improvement that you will see very clearly indeed.

Secondly, of course, there is the race pacing factor. If you are tracking your splits on a hot day, the last thing you want to do is run too fast and blow up before the end of the session on the road. Getting your nutrition and hydration sorted beforehand means you have a turnkey system that not only keeps your speed steady, but stops you from hitting the wall early during a very hard run. That is a steady pace that will win you the race.

Next, naturally, you have the daily recovery factor. When you are finishing a massive session in the sun, the last thing you want to do is skip your post-run fuel and let your muscles stay broken down for a long time. Eating the right items of food means you get your recovery spec'd out so that it not only builds the muscle back, but gets you ready for tomorrow with a lot of energy. That is food that is totally essential for a good rest.

Top 5 Core Features

High Sodium Drinks: When you are running in the heat on a long day, the last thing you want to do is lose massive amounts of salt that leaves you feeling sick on the side of the road. Having this source of fuel in your diet means you keep your levels right so it not only stops cramps, but hydrates you fast for the rest of the run. That is fuel that keeps you safe and running very well.
Liquid Carbohydrates: When you are pushing hard on the road in the sun, the last thing you want to do is try to chew dry food that upsets your stomach and makes you feel very ill. Having this source of fuel in your diet means you get quick energy that not only digests well, but keeps you moving fast without any gut pain at all. That is fuel that is perfect for long and hot days.
Pre-cooling Ice Slushies: When you are standing on the start line in the heat, the last thing you want to do is start the race with a hot core temperature that ruins your pace from the very start. Having this source of fuel in your diet means you drop your body heat beforehand so it not only feels great, but delays fatigue for a long amount of time. That is a benefit that is truly massive for fast runners.
Salty Food Snacks: When you are eating your meals before a long hot run, the last thing you want to do is eat bland items of food that lack salt and leave you weak on the open road. Having this source of fuel in your diet means you load up on sodium that not only tastes good, but prepares your body well to sweat for a long time. That is fuel that keeps your blood pumping very well indeed.
Electrolyte Water Tablets: When you are drinking from your bottle on the move outside, the last thing you want to do is take in plain water that dilutes your blood and causes headaches for the whole long session. Having this source of fuel in your diet means you have a turnkey mix that not only adds flavour, but protects your gut from cramping up on the hard road. That is fuel that is very easy to use every day.

Other Benefits

Firstly, of course, you have the running stomach factor. When you are drinking a lot of fluid in the heat, the last thing you want to do is have it sit in your gut and cause bad pain on a long hard run. Having your exact fluid amounts dialled in means you train your gut to empty fast so that it not only feels light, but gives you water right away to keep your body cool. That is an adaptation that makes running feel great every time.

Secondly, naturally, there is the brain and mood factor. If you are running long miles in the hot sun, the last thing you want to do is feel angry and tired because your brain lacks water and salt for a long time. Keeping your daily fuel sorted beforehand means you feed your brain right so that it not only stops you feeling sad, but keeps your mind sharp and clear for the whole hard session. That is a benefit that is very good for your head.

Finally, of course, you have the night sleep factor. When you are resting after a very hot and hard run, the last thing you want to do is toss and turn because your core temperature is too high for a long time. Getting your daily cooling and hydration spec'd out means your body calms down fast so that it not only lowers your heat, but lets you sleep very well to recover for the next day. That is a deep rest that sets you up for tomorrow.

Finally, of course, you have the social media factor. When you are busy sorting your fuel and running your business, the last thing you want to do is waste hours posting on social media instead of getting your daily training done right. Using an automated system called site2.uk (just like our personal site sundried.site2.uk) means you get a turnkey setup that not only automates all your social posting and marketing, but lets you control it all fully by WhatsApp. That is convenience that is better than anything else out there.
