No sugar coating it: Running in the heat and humidity of the summer sucks. It does. However, if we want to remain active during these challenging summer months of running and have any chance of having a solid racing season come fall, we must continue training. And to make hot weather running enjoyable and safe, the only way is by making substantial adjustments.
I’ve shared summer running tips every year since I began blogging, but this time I decided to do something different. I have gone through my previous writings on the issue and consolidated the tips. These, plus a handful of new ones I’ve added, bring the final count of summer running tips to 39.
To be clear, nobody expects you to apply all 39 of these hot weather running tips on every run. These are just guidelines and suggestions with very short explanations to get your thoughts started. I have included links to posts where I have explored the issues in more depth. And if you’re looking for more background or science behind these summer running safety tips, a quick Google search will point you in the right direction.
So, without further ado, here they are:
1 – Listen to your body – If you feel dizzy, nauseated, or overheated, don’t hesitate to stop, cut the run short, seek shade, ask for help, or just call it a day.
2 – Recognize heat stroke symptoms – Know the difference between exhaustion and heat stroke and familiarize yourself with warning signs like confusion, rapid pulse, or clammy skin.
3 – Hydrate all day – Hydration should be a 24/7 habit that keeps you close to fully hydrated by the time you start your GPS watch.
4 –Don’t overhydrate– Overindulging in water or sports drinks can cause hyponatremia, a condition in which diluted sodium levels may lead to seizures, coma, or worse.
5 – Use electrolytes– Supplementing with sodium, potassium, and magnesium helps your body retain and use the fluids you’re drinking more effectively.
6 – Run early or late – Run before sunrise or after sunset to avoid the most extreme heat and protect your body from overexertion.
7 – Monitor the heat index– Skip your outdoor workout if it’s over 98°F with more than 70–80% humidity, as your risk of overheating skyrockets.
8 – Slow down your pace – Running in the heat is harder, so let go of your pace goals and focus on effort instead of speed.
9 – Accept higher perceived effort – A rise in core temperature, not lactate or heart rate, becomes the main fatigue limiter in hot conditions.
10 – Use effort and time, not pace – In summer, pace and heart rate can be unreliable, so go by effort and run by minutes instead of distance.
11 – Recognize the signs of dehydration – Watch for fatigue, brain fog, darker urine, dizziness, or a dry mouth—these may all signal fluid imbalance.
12 – Prehydrate before long runs – Do not cram your hydration; it doesn’t work that way. Hydrate throughout the day and days, not just before your run.
13 – Rehydrate after running – After a sweaty session, replace fluids with water or an electrolyte drink. Not only as soon as you’re done but throughout the day.
14 – Dress light and bright – Light-colored, loose, and moisture-wicking clothing helps reflect sunlight and allow sweat to evaporate more easily.
15 – Train in the shade – Routes with trees or buildings that block direct sun can be 10–15°F cooler and far more comfortable, and safer.
16 – Freeze your gear – Put your shirt and hat in the freezer before a run to delay overheating and make the first few miles more tolerable.
17 – Take short breaks – Stop for 1–3 minutes during a hot run to drink, throw water on your head, or reset your effort perception.
18 – Use water for recovery – Jumping into a pool, cold bath, or even running through sprinklers post-run can drop your core temp and revive you.
19 – Know where the water is – If you don’t know where the reliable water sources are, run with a handheld bottle or hydration pack.
20 – Run indoors if needed – If conditions are extreme, choose a treadmill or indoor track to get your miles without the heat risk.
21 – Build heat tolerance gradually – It takes a few weeks to acclimate, so ease into hot-weather running instead of diving into hard efforts.
22 – Move workouts around when necessary – Move long or intense workouts to cooler days and use weather apps to plan smarter each week.
23 – Use a heart rate monitor – Heat elevates heart rate, so monitor it to avoid overexertion while running.
24 – Expect it to suck – The first few weeks of heat running will feel awful, but your body will adjust and it will suck less. Proceed with caution.
25 – Adjust your training plan – In very hot climates, push harder workouts like long tempos to the fall and focus on base-building instead.
26 – Exploit cooler days – When temperatures drop, use the opportunity for a strong tempo or threshold session to boost confidence.
27 – Don’t obsess over metrics – During summer training, forget about pace, Strava comparisons, or even distance—survival and consistency are the priority.
28 – Take advantage of trails – Shaded trails provide natural cooling, softer surfaces, and often more enjoyable running when it’s hot out.
29 – Eat hydrating foods – Boost your fluid intake by eating fruits and veggies like watermelon, cucumber, and oranges, which are 80–90% water.
30 – Beware of diuretics – Limit high doses of caffeine or alcohol around runs, as they increase urination and risk of dehydration.

31 – Set hydration reminders – Pair water intake with daily habits like brushing your teeth, meals, or use phone alerts to stay on track.
32 – Sip, don’t guzzle – Drink water steadily throughout the day and during your run to avoid bloating and improve absorption.
33 – Internalize year-round hydration strategies – Treat hydration like a year-round discipline, not just something to focus on when it’s hot.
34 – Know your sweat rate – If you’re a heavy sweater, you may need more fluids and sodium than the average runner.
35 – Pair hydration with daily habits – Combine drinking water with routines like meals, workouts, or bedtime to form easy-to-remember habits.
36 – Double instead of going long – On non-long run days, two shorter sessions may be safer than a longer push under the brutal heat. Consider it if needed.
37 – Use treadmill for quality work – Use a treadmill to maintain pace accuracy or intensity when outdoor heat makes it unsafe.
38 – Keep someone informed – Always tell a friend or loved one your planned route and expected return time, or use live tracking apps.
39 – Know the line between tough and dumb – Being smart and cautious during summer training keeps you healthy and able to run tomorrow.

With Summer around the corner, maybe already here if you are reading this a few days after publication, it\’s essential to adjust your running routines to ensure a safe and effective experience. Running in hot weather requires intentional modifications to prevent dehydration, heat-related injuries, and negative impact on your fitness. These are 12 quick tips for summer running.
1 – Slow Down: Running in the heat is physically demanding, and your body requires more effort to maintain the same pace. Embrace the reality of running at a slower pace to accommodate the increased effort it requires. It\’s about maintaining the level of perceived effort rather than focusing on speed. It doesn’t matter if it screws your Strava averages.

2 – Plan Your Hydration: Proper hydration is crucial during summer runs. Plan your routes around areas with ample fluid sources or strategically seed water along your route in advance. Remember to consume water at scheduled intervals, before you feel thirsty, which may indicate dehydration has already set in.
3 – Overhydration is a Thing: While staying hydrated is important, be cautious about overdoing your water intake. Drinking in excess can lead to hyponatremia, a potentially life-threatening condition caused by dilution of sodium levels in the blood. Stay hydrated throughout the day, not just while you run, and ensure your urine is lightly colored as a sign of healthy hydration.
6 – Dress Appropriately: Opt for light-colored clothing, which reflects more light and deflects heat. Avoid wearing long sleeves, long pants, or outfits designed to induce excessive sweating, as these can hinder your body\’s ability to cool down.
7 – Freeze Your Running Clothes: Sounds weird, but if you place your running shirt and hat in the freezer and you put them on just before you leave home, your body will cool down, and delay the inevitable. Sure, it will get hot anyway, but isn’t it better for it to start at mile 2 or 3 than at the first step?
8 – Stay Connected: Carry your mobile phone during runs. Inform somebody of your whereabouts and expected return time. Consider using apps or services that allow loved ones to track your real-time location for added safety.

9 – Factor in Humidity: If you train in a high-humidity region, be aware that running in saturated air requires more effort compared to drier conditions. Adjust your expectations and accept that maintaining the pace may require additional effort, so you may have to run shorter. Mental preparation and acknowledging this difference may help you stay motivated.
10 – Adjust Your Training Schedule: Be flexible with your schedule, especially if you\’re preparing for a fall marathon. Should the weather conditions be extreme, consider rescheduling long runs or intense sessions to a more suitable time of day. Avoid pushing too hard in unfavorable conditions to prevent extreme exhaustion and/or injuries.
11 – Choose Shaded Routes: Plan your routes intelligently by selecting paths that offer ample shade. This will help shield you from direct sunlight and reduce heat exposure, making your runs more comfortable and safer.
12 – Listen to Your Body: Don\’t be a hero. If you feel dizzy, fatigued, or overheated, don\’t hesitate to stop, cut the run short, seek shade, ask for assistance, or just call it a day. Prioritize your safety and well-being, as taking these precautions will aid in faster recovery and enable you to resume running sooner.
13 – Differentiate Exhaustion from Heat Stroke: It\’s crucial to distinguish between normal exhaustion due to heat and a potentially life-threatening heat stroke. Familiarize yourself with the symptoms of heat stroke to avoid any severe consequences. Refer to the graphic below, borrowed from www.weather.org, for a comprehensive understanding of heat stroke symptoms.

Running during the summer months is possible with the right adjustments and precautions. Many of the world’s greatest marathons, such as Berlin, New York and Chicago, take place in the fall, which means you must train during summer. By planning ahead, making smart choices, and prioritizing safety, you may continue training effectively and ensuring a smooth transition into the upcoming racing season.
Always err on the side of caution and enjoy running while staying safe.
As adults with a full life, alcohol is a ubiquitous part of most of our lives. Some of us enjoy the occasional drink in a social setting, some have one every day, some can’t stop consuming it, and some finally overcame alcoholism.
As far as I have read, there’s no proof that the occasional post-run beer will wreck your recovery, nor that it will help it either. Yet, alcohol has undeniable social benefits associated with consuming responsibly it with your buddies, like after a run. I am not a scientist or a wine drinker, but I’ve read about the benefits of a glass of wine when it comes to HDL cholesterol and antioxidants. I’ve also read how more is not necessarily better. You should not be having 3 or 4 glasses because it the positive effects don’t necessarily compound.
A post-run beer has many social benefits and won’t ruin your recovery. The operating word here is “A”, meaning “one”.
I am not here to proselytize on alcohol consumption, which is a personal choice. But as athletes wanting to improve on our fitness and/or racing times, we need to be aware what are the negative effects that too much alcohol can have on our recovery, which is half of our training (Work + Recovery = Training).
For starters, alcohol is a diuretic. A diuretic is a substance that promotes the increased production of urine. This means that it produces dehydration, a big problem for runners. The consequences of moderate dehydration are, among others, cramps and fatigue. Severe dehydration, which can occur after combining drinking and running, include urinary and kidney complications, low blood volume, heat-related injuries and even seizures. As if that weren’t enough, I am sure that running with a hungover must suck all the joy we could get of the sport.
As I was researching this topic, I googled “alcohol and running” and, among the 812 million results I got, the very first one was this paragraph, which resumes most of what I wanted to say: Alcohol is a powerful diuretic, and dehydration is never a runner\’s friend. The risk for muscle cramps, muscle pulls, muscle strains and general fatigue increases when dehydrated, so drinking extra water after a night of hitting the bars is more than necessary to regulate your body for your next run.”
As we have mentioned in this blog, many times before, the number one recovery tool in your arsenal is sleep, which is the time your body uses to repair itself from the pounding of your training and the stress of your day. Alcohol consumption affects and impairs your sleep. Don’t let anyone fool you by telling you that drinking makes them sleepy like a baby, so it doesn’t affect them. Even if you are asleep, drinking in excess will affect your REM sleep, which restores your brain and is good for your memory and learning. Sounds kind of important to me.
Wine has plenty of documented benefits, but they do not compound the more your drink.
Consuming alcohol in excess, also affects your fitness, which is the capacity of your body to recover so you can do it again. If your liver is too busy processing the excess alcohol you consumed, it would not be able to assist repairing of your body, which is needed after every training session, regardless of how easy it was.
The definition of “excess” is personal and individual. What is suitable for a fit, 200-pound male, may not be suitable for a 115-pound female recovering from Covid. Each runner must understand what is good for their lifestyle and make sure they can live with their decisions.
In a podcast I recently listened, Coach Jonathan Marcus made a comparison between two separate issues. One of those fits perfectly in what the last paragraph was explaining: “You can down a whole bottle of wine in 45 minutes. You can do it. You can, physically, get the liquid into your stomach. But what is going to happen afterwards is not going to be pretty. Or, you can have half a glass of wine in an-hour period, sipping on it though dinner, multiple nights in a row and enjoy it as part of a meal. Your body can extract the nutrients, flavors, etc. from that, versus being overly consumed by the poison of the alcohol that then forces a harsh and severe, nasty metabolic response”.
This post is not for pointing fingers, preaching on lifestyle or proselytizing on the virtuosity of abstention. Just make sure you understand what the consequences of mixing running with alcohol are for both your body and your training, so you can make the right choices when the time comes.
