5 Tips for Running in Hot Weather

With summer season in full swing it’s hot, and it takes extra effort to get out running in hot weather.

Previous experience has taught me that training and running in the heat can be a good idea, especially when prepping for races. I turned up for an Ironman in 2015 with unexpected race day temperatures at 38 degrees Celsius (100 Fahrenheit). It was unusually hot, but the race was on so the hot summer running paid off.

Whilst running your PB in hot weather is almost certainly off the cards, continuing your regular runs is an option if you take a few steps to make your run safe and enjoyable.

1.Adjust your Pace & Listen to Your Body

If you typically train on pace this is probably where you will find a big challenge.

When running in hot weather, you and your body will need to work significantly harder to run at the pace you may be used to. Whilst you may succeed to maintain your usual pace you will be working harder to do so.  You will be pushing your heart rate (HR) much higher than usual. 

Accepting the heat and adjusting your run will be the first big mental step to consider, but a rethink of the run entirely may be an even better idea. 

Instead of running on pace, heart rate based training may be better when running in hot weather. This will be a way for you to  to listen to your body and respect its limits. With an increasing number of sports watches incorporating HR sensors you will only be left with the job of understanding your own heart rate zones and finding a plan to suit you. An increasing number of plans incorporate HR zone training, if you do not already use one, now might be a good time to switch to heart rate based training.

When you switch to HR based training your pace may slow down, especially in the heat. When setting out on a HR based plan, avoid switching to look at your pace, you will feel like you can go faster. Instead respect your heart rate zones and run within your bodies limits.

2. Hydrate, Hydrate, Hydrate

This is good advice for any time of year, but if you are plan to go running in hot weather, increase your intake of fluids starting the day before. With a likelihood for increased sweating during a hot run, you will be losing more fluids and minerals that need replenishing.

In order to replace the minerals lost in your sweat, drink electrolyte based drinks before, during and after your run to ensure that you are striking a balance between the loss of fluids and your intake.

Running with a water bottle can take some getting used to,  but when running in hot weather it’s not really negotiable. There are an increasing number of solutions to carry your water bottles so you will be able to find one that makes you feel comfortable. Here are a few suggestions.

Save yourself some drink for when you finish your run, typically this is when the heat suddenly hits so having some of your drinks left at this point is always good.

How much should you drink? This depends on how much you sweat. It is worth using one of your runs to understand your sweat rate so that you can adjust your consumption to your own personal body needs.

3.Pick a Hot Weather Friendly Route

Whilst this may not matter on a regular day, on hot days you will want to spend as much time as possible outside of direct sunlight. A path under some trees by the side of a lake is perfect as you will benefit from the shade and if there is a breeze you may benefit from some of the coolness of the water. Avoid any runs in city centres where you will be faced with concrete, glass reflections, traffic and pollution. Instead try make it to local parks where the chance to find some fresher air is slightly higher.

4.Choose Your Time of Day Wisely

Getting into morning running is a good idea,  and evening runs once the sun sets can bring some cooler air.

If you live in a place where both day and night remain consistently hot the choices get tougher. Sure, getting out of direct sunlight helps, but evening runs can bring a pressing heat and also brings out the mosquitoes (depending on where you live), and we know mosquitoes love runners!

Whilst I keep an eye on the weather map and any drop in temperature, I also look out for moving trees and a cooling breeze.  A potential rain shower is always good with the hope that the moment after the rain may bring a brief moment of cooler air.

If you are training for a race there are other things to consider. When doing a triathlon (especially long distance) you will most likely hit the run around mid-day and you may need to train for running in hot weather. If your race day is in a hot location, this is something you may way to train to get used to.  On race day avoiding the hottest part of the day may not be an option. It might be better to understand how to manage this type of run than to be surprised on race day.

5.Protect Yourself Against the Sun

This is no different to any other day in the sunshine, but when you are running in hot weather you may not feel the sun in the same way as you do when lying on the beach. When you are on the move you will feel a breeze on your skin and you may be in and out of the shade. Getting your sunscreen on is a must.

A running cap that can absorb sweat and protect your head and sunglasses are important accessories not only to protect yourself but a cap can also be a useful tool to keep you cool.  Try dipping it in some cold water whilst on your run.  What is important is to keep your body as cool as possible on both the outside and the inside.
