How To Adjust Your Training For Summer Running in the Heat

Summer can be a challenging time for runners, especially if you are training for a race. Fall races are great because of the cooler weather on race day, but it usually means you are training in the summer heat. There are many considerations for summer running in the heat, such as safety and adjusting paces. Let’s talk about some ways to adjust your training to run in the summer heat.

Summer can be a challenging time for runners, especially if you are training for a race. There are many considerations for summer running in the heat, such as safety and adjusting paces. Let's talk about some ways to adjust your training to run in the summer heat.

How To Adjust Your Training For Summer Running in the Heat

Allow your body to acclimate to the heat

Those first few runs in the heat can be really challenging. But after a few weeks, you start to acclimate. It doesn’t necessarily feel easy to run in the heat, but you get used to it. As you are acclimating be sure to take it easy and carry water, and take walk breaks as needed.

Adjust your schedule based on the weather

As you plan out your week of training, check the weather forecast. If there is thunder and lightning predicted one day, make that your rest day. On days it will be extra hot and humid, try to make those your easy run days. If it’s a particularly brutal week maybe you can make it a cut back week, or plan to run your hardest workout on the treadmill. This may not always work with your schedule, but it’s worth a try.

Run at the coolest times of day

Early in the morning or night time are the coolest times, so try to get your runs done then, when the sun isn’t out in full force. Keep in mind that mornings might have the coolest temperatures, but usually the humidity is the worst (at least here on the east coast).

Find ways to cool yourself off

Try bringing a frozen water bottle, a cold towel, or some ice to put in a hat. Or just have some of these cold items ready to use when you get home! If you drive somewhere to run consider packing a small cooler so you will have a cold drink when you are finished.

Focus on hydration

It’s extra important to stay hydrated in the heat. Not only do runners need to drink water, but electrolytes will help as well. Make sure to follow these hydration tips for summer runs in the heat! You will also want to have comfortable ways to carry your water with you on your runs, too.

Try to run in shaded areas

As much as possible, try to find shade if you are running when the sun is up. Trails are a great option for this if they are surrounded by trees.

Run by effort in the summer heat

Try to ignore your GPS watch, or better yet, leave it at home! Especially for easy runs, don’t worry about your pace. You may find that you run significantly slower in the heat, and that’s ok. It’s more important to focus on effort. There are other ways to monitor your run instead of pace, such as the talk test or heart rate.

Adjust your training for speedwork

Speedwork is extra challenging in the summer heat. There may be times when you need to adjust your workout, run it on the treadmill, or skip it all together. Running by time (vs distance) is a good option in the summer, as well as doing fartlek runs rather than pace-based speed workouts. Here are more tips for doing speedwork in the heat.

Dress appropriately for summer running in the heat

Make sure to wear light, sweat wicking clothes on summer runs. Invest in some high quality socks so you avoid blisters. Consider wearing a hat, visor, or sunglasses. Don’t be afraid to run in just a sports bra if that is more comfortable for you! When you’re running after sunrise be sure to wear sunscreen. And use body glide…lots of body glide!

Embrace the treadmill

When the weather is really brutal, or you just don’t feel like dealing with the heat, don’t be afraid to opt for the treadmill. You will be able to get in a good workout and it will give you a break from the heat!

Don’t be afraid to skip a run

As runners we usually want to push through and complete every run on our training plan. But sometimes that’s not the best idea! Don’t be afraid to skip a summer run in the heat when you need a break.

Safety First

Even with all the summer running tips, there are still some days when it simply isn’t safe to run outside. Lightning and extreme heat are dangerous for runners. You will need to know your own limit for running outside in the heat, but remember to factor in the humidity when you’re checking the weather.

Remind yourself that fall is coming

Mentally, running through the summer heat can be a challenge. Remember than fall is coming and your hard work now will pay off for your fall race!

Hopefully that gave you some ideas or reminders for adjusting your training in the heat. Remember to enjoy summer running because winter is right around the corner!

    These are great tips, Lisa.
    When it’s warm, I do my long runs early in the morning in the forest. It’s amazing what a difference it makes if you can run in the woods!
    For shorter runs, I just suck it up and run in the heat. I don’t mind it too much and it helps me to acclimatize for hot races. At least, that’s what I hope for!

      It is important to get used to the heat for races! Usually they are not super early and you can’t control the shade on the course.

    Great tips. I do all you mentioned except the treadmill.

    It’s important to be realistic with your pace goals also when the temps are rising.

    • Lisa @ Mile By Mile says

      June 30, 2022 at 4:37 am

      Definitely! For many of my runs, especially long runs, I try not to even look at the pace on my watch.

    Summer running definitely has its challenges (and potential danger risks as well). I think the best we can do for ourselves is to just go with what Momma N gives us, and adjust our training and goals as needed. A few altered workouts probably won’t affect an entire training cycle.

    • Lisa @ Mile By Mile says

      June 30, 2022 at 4:39 am

      Very true. Although last summer I felt like my training was very challenging with an early October marathon. It seemed like I was constantly adjusting my runs and slowing my pace, and it didn’t even cool off that much by race day.

    speedwork in the heat is a killer! When is fall again?

    • Lisa @ Mile By Mile says

      June 30, 2022 at 4:39 am

      It’s so hard to push the pace in the heat!

    Ha, I went down a rabbit hole here and read a bunch of your older posts, including the one about doing speedwork in the heat. I was just doing speedwork this morning and thought “Wait a minute! Didn’t I run my last Turkey Trot faster than this?” Oh yeah… it’s way hotter now. You just have to adjust. I live in Florida so there’s no way to avoid the heat, we just have to get acclimated and then suck it up. Great tips!

    • Lisa @ Mile By Mile says

      Yea, it must be really hard to train there! My paces are so much different in the summer vs the winter. Especially for workouts and races.

  6. Chocolaterunsjudy says

    Summer is definitely really challenging — especially since people are often beginning to train for longer races!

    All great tips, Lisa — thanks!

    • Lisa @ Mile By Mile says

      June 30, 2022 at 4:41 am

      Last summer I trained for a marathon from June through October which were the hottest months of the year! I realized I prefer November marathons so its cooler by the end of the training cycle.

  7. Jenn says

    Down here, we just have to slow down, grin and bear it. The humidity doesn’t necessarily reduce at night, and night brings the bugs. No, thank you!

    • Lisa @ Mile By Mile says

      June 30, 2022 at 4:42 am

      I dont really like running at night either. The mornings are ok, but still humid.

  8. Denise says

    We were on the same page this week. I guess summer heat is on our minds. I do all these things except the treadmill.

    • Lisa @ Mile By Mile says

      June 30, 2022 at 4:42 am

      Yes, its that time of year when we are all starting to deal with the heat!

  9. Janelle @ Run With No Regrets says

    July 2, 2022 at 10:09 am

    Really great tips and a reminder that the morning runs can be more humid – I certainly suffered the humidity this morning! And I need to get back to carrying hydration and electrolytes as I get back in the swing of summer running!

    • Lisa @ Mile By Mile says

      July 6, 2022 at 5:23 am

      It can be so tough! Carrying some water/electrolytes definitely helps. Especially on long runs!

  10. Catrina says

    July 30, 2025 at 2:38 am

    So many great reminders here! Strangely, we’ve been having a very cool summer with a lot of rain. I even had to wear a long sleeved shirt yesterday. I’m not complaining, it’s so much easier to run in cool weather!
    Do you find summer training makes your fall races feel easier?

  11. Deborah Brooks says

    July 30, 2025 at 9:21 am

    these are helpful tips for running in the heat. I used to consider myself a summer warrior-but I’ve lost interest and I am ready for fall

  12. Debbie says

    August 1, 2025 at 10:05 am

    I gave up training for fall marathons long ago. It’s just too much trying to run 20 miles when it’s already 90 degrees by 7 am. Even if it is a dry heat!

Spent almost every step of this 21 mile run questi Spent almost every step of this 21 mile run questioning my life choices. Like waking up at 3am to run 12 miles on the treadmill and 9 outside. This was a crazy week with a kid that wasn’t sleeping great and fighting a cold and super busy days at work. My legs were just tired the whole time today. It was really hard to run outside after so many treadmill miles and my pace was much slower than inside.

I reminded myself that this is peak week. It’s supposed to feel hard. If it was easy everyone would do it. I ran 53 miles this week and am not injured. The weather is perfect. I’ve gotten in every planned run of this training cycle so far.  I get to do this. 

And I managed to finish strong with my last 3 miles the fastest of the (outside) run. I owe that to a solid fueling plan and taking all my gels even when I really didn’t want to.

3 weeks to go until race day!

#running #marathontraining #longrun
Yesterday’s long run was followed immediately by Yesterday’s long run was followed immediately by back to back kid activities, so there was no time to post about it. (I ate breakfast in the car and lunch at soccer practice- it was that kind of a day.) I was kind of nervous going in to this run, especially now that I’m getting down to last few key long runs. I had 16 miles with 4 x 2 miles on the plan, which sounded manageable but also challenging. The weather was perfect and I hit all my paces. At the end I got a little confused- thinking I was at 15 miles but I was actually at 14 🙃 Got home and realized I chafed really bad. Another long run down, and another week closer to race day.

Do you ever psych yourself out before long runs?
