Exercising in the heat will inevitably elevate your heart rate and elevate your needs for hydration. This means that with more effort you will accomplish less. The sooner you accept it, the quicker you will adjust to your new reality of running in summer.

Running writer Brownyng Griffiths, puts it this way in her Polar blog: “After all, exercise should be a celebration of your body’s capabilities, not a battle against the elements. So, stay cool, have fun, and keep moving”.
This said, here are 11 tips to take into consideration to improve, enjoy and be safe during your summer running:
1 – Adjust your intensity: If you can take one thing from this blog post, let it be this one: The body keeps your skin cool by circulating blood. The hotter you get, the more blood pumping is needed, thus, a faster heartbeat, thus, you work harder, thus you will tire faster, thus, accept it and adapt. Your performance won’t be the same, but if your main running goal is not coming up next week, you have enough time to adjust your intensity to your reality.
2 – Be intentional about your hydration: Hydration is not just for when your Garmin is running. Intentionality is the name of the game. When you hit that start button you should have been consuming a balanced mix of water and electrolytes throughout the day. And not just during running days but every day. Same applies to post-running rehydration. You don’t have to replenish every drop as you lose it, but you must understand what your body requires to function properly.
3 – Plan your water stations in advance: know where the water stops are, what gas stations are open at the time you run or plant your water on the route ahead of time. If you are not sure about will be available, carry what you will need. There are countless options available in your local running store. Running holding a bottle in your hand should be avoided unless it means no water.
4 – Overhydration is a life-threatening condition: It may be counter intuitive, but you can drink yourself to death. Hyponatremia is a potentially fatal condition where an individual’s level of sodium gets so diluted by the combination of over guzzling of water and not replenishing electrolytes that the body’s electrical system fails. Understand how much water you need and/or can manage.
5 – Your body should adapt. Be patient: I’ve read experts stating the body takes about two weeks to adapt to running in the heat. In my experience it takes much longer. But if you are patient, understand your output will not be the same as in benevolent weather, and remain constant, your body will eventually acclimate and improve its ability to remain cool.

6 – Know your environment (BE FLEXIBLE): Knowing the weather for your run is just a click away. There is no excuse to be unprepared on a hot and/or humid run. Pushing back or rescheduling your run may be the wise choice. Or jumping onto the dreaded treadmill. Don’t just check the temperature, but also the heat index, which measures how hot it feels outside when combining air temperature and relative humidity. Overlooking it may get you into the danger zone.
7 – Choose light-colored clothing: I’m sure your dark shirt is beautiful, and that black hat from that important marathon will raise your profile with your running buddies, but it is about basic physics. Dark colors absorb the heat of the sun and get hotter while light colors reflect it and are cooler. That simple.
8 – Wear the right clothing: Breathable, moisture-wicking clothing will aid sweat evaporation and thus, cooling of the skin. Wear as little as you can feel comfortable with. Avoid tight materials that will stick to the body and hinder evaporation. Remember that sweat and evaporation is what will keep you cool and healthy.
9 – Know your route: The middle of the summer is not the time for exploration. You don’t want to find yourself lost and short on hydration in an area where there’s not another soul or a shaded area to be found. Know where you are going, know where the water is, know where the shaded areas are. This could be the difference between success and disaster.
10 – Understand your body signals: Heat will affect us all. It is a matter of the degree to which it will happen. It is not an if, but a when. Learning to recognize dizziness, cramps, cold sweats, or fatigue could help you identify heat exhaustion or the dangerous heats stroke. This is not the time to show your machismo by plowing through a hard workout when you are exhausted.
11 – Protect your body: It is not just about the sunscreen. Your eyes, your head and your face also need protection during the brutal summer runs under the sunlight. Wearing sunglasses and a cap/hat, even when it is cloudy, is always a good decision.
Keep on moving, keep on training, remain constant. Those who do are the ones that will set up PRs during the Fall/Winter running season.

We’ve heard about the pee test to figure out how well hydrated we are or not. If the pee it is clear, or pale yellow, then you are hydrated and ready to run; if it is yellow or darker, then you are dehydrated. Sure, this is a quick, easy and free test, but it does have some limits.
The need for sodium for us, long-distance runners, goes beyond the recommended guidelines
According to Andy Blow, a British Sports Scientist, the pee test is a good tool to gauge the general state of your hydration, but it is not the end-all word on the issue. “The time to look at your pee is when you wake up in the morning—Says Blow, who served as hydration specialist for two Formula 1 teams—because the color of the urine you first produce is a good indication if you are hydrated or not that day. By then, your body had all night to recalibrate itself, move fluids around and get into equilibrium. If you wake up and you feel a little bit thirsty, it is a good indication you are dehydrated.”
The problem of looking at your pee during the day is that you eat, you drink, you do things and the results become skewed. If you had a bottle of water, or two; if you drank a coffee, or two; or a sports drink, your body may be discarding a lot of the fluid it took in, which doesn’t mean you are fully hydrated. Even if your urine is clear as water.
Remember that dehydration doesn’t get solved chugging a gallon of water. If you are in a dehydration state, it may take your body 24-48 hours to recover. You can gulp all the Gatorade you want, yet this will not restore you. The body can’t absorb it all and most of that excess water will be peed out.
Dehydration doesn’t get solved by chugging a gallon of water (or five)
In a recent interview I heard, Mr. Blow explained that we see with a lot of overhydrated athletes at the starting line of races. They take a lot of water before starting and that has nothing to do with their state of hydration. A recent study showed that a significant percentage of athletes are in an early state of hyponatremia when they start long races on hot days, most likely because they prepare by drinking a lot of water to confront the weather conditions. They end up peeing the excess water, and valuable sodium with it, which eventually leads to trouble.
The best way to address this, according to Blow, is to ingest a much smaller amount of a high-sodium drink. This sodium will make it into the bloodstream and will hold water there as a reservoir so that you have something extra when you start. “This is a lot better than drinking loads and loads of water”, he affirms.
Sprinkling salt in a glass of water will do the trick. The right amount is about 1.5 grams of salt per liter of water consumed. But since it is hard to drink “ocean water”, Andy Blow recommends sodium citrate, which is more palatable. Sodium citrate can be purchased at a nutrition store or via internet. This is about three times stronger that any commercial sports drink.
Understand that a higher consumption of sodium is important for athletes that train a lot AND sweat a lot, like us as long-distance runners. Consuming all this sodium for sedentary people is not recommended. Our salt requirements can be up to three or four times more than those of sedentary people. That is why we crave salty stuff, such a pretzels or potato chips, after a hard training session.
Also, understand that you don’t need to replace 100% of what you are losing. You are supposed to sweat and lose electrolytes. Nothing wrong with that. You need to find the sweet spot between what you are losing and going hyponatremic; and from there, test what works better for you. Then, go check your morning pee.

The basic concepts on hydration have moved like a pendulum through the last century of athletics in general but running in particular. While the earlier runners of the Boston Marathon took it as a matter of pride not to consume water, in later years the thesis of never been able to consume too much came en vogue and was disproven. Now days, we are in the “drink to thirst” phase. The truth is that there is not a one-size-fits-all approach to the matter. What worked for Bill Rodgers in the 1970s, does not work for Eliud Kipchoge, setting the world record and does not necessarily work for you, right now.
When it comes to hydration, extremes do not work. Not taking any liquids during a marathon is a recipe for disaster that doesn’t require much explanation. The “more is better” can lead to the life-threatening condition known as hyponatremia, whose explanation is beyond the scope of this blogpost.
It is important to understand that if you are running 3-6 miles, 3-4 times a week, your body may have everything it needs to cope with your hydration needs. There should be no need for a hydration strategy per se unless you are running in an oppressively hot and humid environment. A quick 5K around my block is not the same as 5K in the Sahara at noon. But once you are getting up on mileage, or start training for a longer effort, then it becomes imperative that you do something about your hydration needs.
“Hydration is a balancing act—says Andy Blow, British Sports Scientist and founder of Precision Hydration—One thing we can all agree is that once you hit a level of under-hydration, where you lose enough fluids and electrolytes, at some point you will reach serious problems, such as reduced cardiovascular function because your blood gets thicker and thicker as you get more and more dehydrated. Then you dissipate heat less well, you overheat and from there you get into a downward spiral.”
Finding out where in the spectrum you fit; how much you need to drink, how often and what electrolytes you need to replace is your responsibility as a runner. Sure, a coach can and will assist you, but only if you feed him the right data, which is your duty.
Hydration Specialist and Sports Scientist Andy Blow
An easy home test to figure out how much you sweat on a specific setting, let’s say on a summer long run; is to weigh yourself naked right before you leave. Run for an hour without consuming anything. As soon as you get home, get naked, wipe yourself off and weigh yourself, again. The difference in weight is how much sweat you lost in an hour. Each gram lost is equivalent to about 1 milliliter of water, as there are other contents in your sweat (in the Imperial measure system, each tenth of a pound is equivalent to 1.6 Fl Oz). This is your sweat rate and the approximate amount of water you need to replace as you run in similar conditions. Yes, it is that simple.
As personal as the sweat rate is, the contents of your sweat are equally individual. You need to know what is in your sweat so you can replace it. If you are caked in salt once the sweat evaporates, then you are losing a lot of salt, 40% of which is sodium, a key electrolyte. So, if this is you, you need to go above the set guidelines for salt intake, as these are not for athletes but for normal, inactive people.
According to Blow, the best approach for hydration on shorter runs (90 minutes or less) is not to have a plan but to drink to thirst. For longer runs, like a 20-miler on a hot summer day, you need to consume not only water but also sodium to compensate what is being secreted and keep your stores as topped off as possible.
There is so much more about hydration. Not all of it can be addressed in just one post. Tim Noakes, the world renowned South African sports physiologist, wrote “Waterlogged”, a book about the topic which is 448 pages long. If you want to dig deeper into the subject, this is my recommended source.
