Runner training on a summer evening – marathon preparation tips from Bog Dog Running

Top 5 Summer Marathon Training Tips: How to Beat the Heat and Keep Running Strong

Are you gearing up for an autumn marathon? While the race might still be a few months away, the bulk of your training happens during the hottest months of the year. Summer running can be brutal—but with the right approach (and the right gear), you can keep your training on track and even enjoy the miles along the way.

At Bog Dog Running, we know a thing or two about pushing through summer training blocks. Here are our top tips for staying cool, safe, and strong while clocking up the miles in the heat.

1. Hydrate, Hydrate, Hydrate

This one’s non-negotiable. When the temperature rises, so does your risk of dehydration. Make sure you’re drinking water before, during, and after every run —especially on long runs or tempo sessions during peak heat.

We recommend using a hydration vest or handheld water bottle to stay topped up on the go. Check out our range of lightweight, runner-friendly hydration solutions from Montane—perfect for long summer runs. Smart hydration strategies are a key part of every successful marathon training plan.

2. Don’t Forget Your Electrolytes

When you sweat, you’re losing more than just water. Electrolytes like sodium, potassium and magnesium are essential for keeping your muscles firing and preventing cramps, especially on long runs or after high-intensity workouts.

We stock a full range of High5 Sports Nutrition including electrolyte tablets, powders and on-the-go chews—ideal for mid-run fuel or post-run recovery. Incorporating these into your summer running nutrition routine can help reduce fatigue and aid performance in hot weather.

3. Protect Your Skin

Even on overcast or windy days, UV rays can sneak up on you—especially during long runs that stretch into multiple hours. Make sunscreen part of your pre-run ritual and reapply if you’re going the distance. Pairing sunscreen with a cap or visor helps protect your face and scalp too, which are easy to overlook.

4. Dress for the Conditions

Stay cool by wearing technical summer running gear designed to wick away sweat, improve ventilation, and reduce the risk of chafing. Avoid heavy cotton and look for light, breathable fabrics specifically made for hot weather running.

A lightweight cap and sunglasses can make a huge difference on bright days—shielding your eyes, reducing glare, and helping you stay focused on your pace. We love the bright, bold designs from Runr for caps and headwear, and Goodr Sunglasses for fun, functional eye protection that won’t bounce or fog up during sweaty runs.

5. Listen to Your Body

Summer training doesn’t mean you need to push through every session at full throttle. It’s OK to slow down, take walk breaks, or even cut a run short if it’s dangerously hot. Adjust your pace expectations based on temperature and humidity—it’s all part of smart, injury-preventing training.

Being consistent is more important than being fast. If you’re tired, dizzy, or light-headed—stop. Use those signs as feedback to rest, rehydrate, and recover. Summer training is about adaptation, not perfection.
