Sweat, Sun & Stamina: Why Athletes Need Sunscreen That Goes the Distance
From marathon training and mountain adventures to open-water swimming and a leisurely round of golf, your skin works just as hard as you do. Isn't it time your sunscreen kept up?

The Only Thing That Should Be Burning Is Your Muscles
It's kilometre 18 of your morning run.
Your legs are beginning to complain, your running watch is telling you something you'd rather not know, and you're questioning the wisdom of that extra glass of wine last night.
The sun is shining, the sweat is flowing and you're thoroughly enjoying yourself. Well, mostly.
But there's something you probably haven't thought about since leaving the house.
Your sunscreen.
You applied it before heading out. Excellent work. But after nearly two hours of sweating, wiping your forehead and rubbing against your running kit, how much protection is still where you put it?
It's a question worth asking.
Because whether you're a weekend cyclist, dedicated triathlete, keen golfer or someone who simply loves being outdoors, your skin faces some unique challenges when you're active.
And just like your trainers, equipment and clothing, your sunscreen needs to be suited to the job.
Sport Is Tough on Your Skin. Really Tough.
Let's think about what happens during a typical outdoor training session.
You're sweating. Your body temperature rises. Your clothing moves against your skin. Perhaps you're swimming, cycling through a headwind or running beneath the midday sun.
Individually, these things might not seem particularly dramatic.
Together, they create demanding conditions for your skin.
And for your sunscreen.
Sweat: Your Body's Built-In Cooling System
Sweating is essential. It's how your body helps regulate temperature when you're exercising.
But heavy perspiration can also affect sunscreen coverage, particularly when combined with rubbing, wiping or towelling your skin.
If you've ever finished a run with sunscreen running towards your eyes, you'll understand why choosing the right formulation matters.
Friction: The Problem Nobody Talks About
Running vests, cycling jerseys, hydration packs, helmet straps and towels all create friction.
Over time, repeated rubbing can disturb sunscreen coverage, leaving areas of skin less protected than you intended.
And those exposed shoulders, necks and forearms are often the very places receiving the most sunshine.
Water: Wonderful for Swimming, Less Wonderful for Sunscreen
If you're a swimmer, sailor, paddleboarder or triathlete, water resistance is particularly important.
Water can reduce sunscreen protection, and repeated swimming, towelling and changing conditions make maintaining coverage more challenging.
That's why a suitable, highly water-resistant sunscreen should be part of your equipment.
Right alongside your goggles, wetsuit and that ridiculously expensive piece of carbon fibre you convinced yourself was essential.
The EVY Difference: Swedish Technology Built for Real Life
At EVY Technology, we've always believed that sun protection should support the things you love doing, rather than get in the way.
And that's particularly important when those things involve sweat, water, movement and hours spent outdoors.
Developed in Sweden, EVY uses patented mousse technology that works differently from many conventional sunscreen creams and lotions.
Rather than simply resting as a surface film, EVY's formulation is designed to distribute UV filters throughout the uppermost layer of the skin, helping create durable, even coverage.
This technology is designed to improve resistance to the effects of water, perspiration and everyday friction.
The lightweight mousse also supports the skin's protective barrier, helping it maintain moisture and comfort when exposed to challenging conditions.
Think of it as skincare designed for life in motion.
Not just lying on a beach towel.
Although we're rather fond of that too.
Tested for Endurance, Not Just a Day at the Beach
Here's the rub (excuse the pun) EVY is for people who spend serious time outdoors.
EVY's sunscreen technology has undergone extensive durability and water-resistance testing.
In one laboratory assessment our SPF50 formulation was subjected to repeated cycles of water exposure and drying over an eight-hour period.
After testing, the measured SPF remained at approximately SPF35.
That's an impressive demonstration of the formulation's durability under those specific laboratory conditions.
It doesn't mean sunscreen can be applied once and forgotten for eight hours. Real-life activity, application amounts and UV conditions vary enormously, and regular reapplication remains essential.
But it does illustrate why EVY's technology is especially interesting for swimming, sport and outdoor endurance.
Durability isn't about ignoring sunscreen. It's about choosing a formulation designed to withstand the demands you place on it.
And when you're training for an event that lasts several hours, that is so important.
From Ocean Crossings to Mountain Expeditions
Now, we're not suggesting that everyone needs sunscreen designed with extreme adventures in mind.
Your Saturday morning Parkrun probably isn't quite as demanding as rowing across the Atlantic.
Although that final kilometre can certainly feel like it.
But EVY has a fascinating history of being used in some genuinely extraordinary sporting environments.
The Atlantic: Where There's Very Little Shade
Imagine rowing across the Atlantic Ocean.
Day after day, you're exposed to sunshine, salt water, wind and relentless physical effort.
There's no convenient café, no shady tree and certainly no popping indoors when the UV gets a little intense.
Atlantic rowing competitors Fredrik Abellin and Viktor Mattsson are among the endurance athletes featured by EVY Technology.
Their challenge illustrates the kind of environment where durable sun protection becomes an important piece of personal equipment.
For ocean athletes, protecting exposed skin isn't merely a matter of comfort.
It's part of preparing for prolonged exposure in demanding conditions.
Adventure Racing: When the Environment Never Stays the Same
Adventure racing is a remarkable test of human endurance.
Competitors can spend extended periods trekking, running, cycling and navigating across difficult terrain.
Weather conditions change. Temperatures fluctuate. Clothing becomes wet. Sweat and friction are constant companions.
World-class adventure racer Mikael Lindnord and the AXA-Adidas Adventure Racing Team are also featured in EVY's athlete history.
These environments highlight the importance of equipment and skincare that can cope with unpredictable conditions.
Because halfway through an endurance event isn't the ideal moment to discover your sunscreen isn't suited to the task.
Sailing: Sun, Salt and the Open Sea
Professional offshore sailing presents a unique challenge.
You're surrounded by water, exposed to reflected sunlight and constantly dealing with wind, spray and changing weather.
EVY has been associated with competitors and crews involved in major offshore sailing events, including the Whitbread Around the World Race and Volvo Ocean Race.
In these environments, sun protection is an everyday necessity rather than an occasional afterthought.
Salt water, constant movement and long periods outdoors make sunscreen durability and skin comfort particularly valuable.
And if you're wondering whether these lessons apply to your weekend sailing trip around the Solent, the answer is absolutely.
The scale of the adventure might be different.
The principles of sensible sun protection are much the same.
You Don't Have to Be an Elite Athlete
Here's the really important bit.
Most of us aren't planning to row across an ocean or run through a desert.
And that's perfectly fine.
Some of life's greatest adventures are a little closer to home.
Running and Marathon Training
Long training sessions can mean hours of exposure to sunshine, wind and sweat.
A lightweight, non-greasy sunscreen can be particularly welcome when you're working hard.
Pay attention to your face, ears, neck, shoulders and arms, and remember that rubbing your face or wiping away sweat can disturb coverage.
Cycling
There's something wonderful about heading out on a bicycle for a few hours.
The fresh air. The open road. The café stop that somehow becomes the highlight of the ride.
But cyclists can spend extended periods exposed to UV radiation, often without realising how strong the sunshine is because moving air helps keep them cool.
Don't forget the back of your neck, ears, knees and other exposed areas.
And yes, the coffee stop is an excellent opportunity to reapply.
Swimming and Triathlon
For triathletes and open-water swimmers, water resistance is essential.
But so is remembering that no sunscreen is completely waterproof.
EVY's extra water-resistant formula is designed to provide durable coverage during swimming and demanding activity.
Apply generously before your session, allowing time for the product to settle, and follow reapplication guidance after swimming and towel drying.
Golf and Tennis
Not all endurance sports involve gasping for breath.
A round of golf can mean four or five hours outside, while a long tennis match can involve repeated exposure to sunshine, perspiration and physical activity.
That's a substantial amount of time for your skin to be exposed to UV radiation.
Comfortable sun protection matters, particularly if you're wearing it for several hours.
And while sunscreen might not improve your putting, it's certainly a worthwhile addition to your golf bag.
Hiking, Skiing and Mountaineering
It's easy to associate sun protection with hot weather.
But the mountains tell a different story.
UV exposure increases with altitude, while snow and ice can reflect additional UV radiation towards your skin.
That means sunscreen is important for skiing, snowboarding and high-altitude trekking, even when the temperature is well below freezing.
EVY's performance-focused formulation is designed for demanding environments, from summer sunshine to winter adventures.
SPF30 or SPF50: Which Is Better for Sport?
It's a question we hear regularly.
And the answer depends on your skin, the UV conditions and the type of activity you're planning.
Both SPF30 and SPF50 can provide excellent UVB protection when applied correctly.
Here's how they compare:
| Protection | Approximate UVB filtered |
|---|---|
| SPF30 | 96.7% |
| SPF50 | 98% |
The difference might look modest, but SPF50 allows approximately 40% less UVB radiation through than SPF30 under standard testing conditions.
For prolonged outdoor activity, intense sunshine, high-altitude environments or particularly sun-sensitive skin, SPF50 offers a useful additional margin of protection.
For many everyday outdoor activities, SPF30 may be suitable when used properly.
Whatever you choose, make sure the sunscreen provides strong broad-spectrum UVA and UVB protection.
And remember: higher SPF doesn't give you permission to stay in the sun indefinitely.
Five-Star UVA Protection: Another EVY Advantage
Most people understand SPF.
But there's another rating worth knowing, especially if you spend a lot of time outdoors.
The Boots UVA Star Rating measures how balanced a sunscreen's UVA protection is relative to its UVB protection.
UVA contributes to skin ageing, pigmentation changes and skin cancer risk.
And unlike UVB, UVA exposure is not necessarily accompanied by the obvious warning sign of sunburn.
EVY's sunscreen range has achieved the highest classification under the Boots UVA Star Rating system: five stars.
This demonstrates a particularly high balance of UVA and UVB absorption, as measured under the test.
Combined with the appropriate SPF, this gives outdoor enthusiasts an additional reason to consider EVY for their sun protection needs.
Because looking after your skin isn't simply about avoiding sunburn today.
It's about protecting your skin health over years of adventures.
A Breathable, Lightweight Formula Makes All the Difference
Let's be practical.
Nobody wants to start a training session feeling as though they've been covered in cooking oil.
Heavy, sticky sunscreen can be especially unpleasant when you're exercising.
It can make clothing feel uncomfortable, leave a greasy residue and generally become one more thing you wish you didn't have to think about.
EVY's mousse formula is designed to absorb comfortably without leaving a heavy surface film.
Once settled, it feels lightweight and non-sticky, making it particularly appealing for active lifestyles.
The formulation is also designed to allow the skin to breathe and perspire naturally, while supporting its protective barrier.
It's an important combination.
Your skin needs to do its job while you're exercising.
Your sunscreen should work alongside it.
Don't Forget Your Skin Barrier
Here's something endurance athletes often overlook.
We spend a great deal of time thinking about how to help our muscles recover.
We stretch, hydrate, eat protein, foam roll and occasionally persuade ourselves that an ice bath is enjoyable.
But what about our skin?
Your skin is exposed to repeated challenges during sport.
Sweat, wind, salt water, friction, temperature changes and frequent washing can all contribute to dryness and irritation.
The skin barrier is your body's natural protective system, helping prevent excessive moisture loss and protect against external irritants.
EVY's patented skincare technology is designed to support this barrier, helping the skin retain moisture while providing sun protection.
It's one of the reasons EVY is more than simply a conventional sunscreen.
It's sun protection developed with skincare in mind.
And after a demanding training session, your skin deserves a little recovery too.
The Sports Sunscreen Routine: Before, During and After
Good sun protection doesn't need to be complicated.
But a little preparation goes a long way.
Before Your Session
Start with clean, dry skin.
Shake your EVY mousse can, hold it upside down and dispense a generous amount.
Work the mousse into a liquid between your hands and spread evenly across exposed areas.
Follow the product's application guidance and allow it to settle before getting dressed or beginning your activity.
For EVY SPF50, the manufacturer recommends allowing approximately 5–10 minutes for the mousse to settle.
Don't forget easily missed areas such as your ears, neck, shoulders and the backs of your hands.
During Your Session
Keep an eye on the conditions.
Check the UV Index, wear suitable clothing and headwear, and make use of shade whenever practical.
Reapply sunscreen generously at least every two hours during prolonged exposure and after swimming, heavy sweating, towel drying or significant rubbing.
If you're taking part in an organised race, consider how you'll access sunscreen at suitable points.
A little planning can save a lot of discomfort later.
After Your Session
Once you've finished, gently cleanse your skin to remove sweat, dirt and product residue.
Avoid unnecessarily harsh cleansing or excessively hot water if your skin feels dry or sensitive.
Then replenish moisture with a suitable skincare product.
EVY's REPAIR Mousse can be a useful part of an evening skincare routine, particularly when your skin needs additional hydration and barrier support.
After all, recovery is part of performance.
And that applies to your skin as well as your muscles.
Five Mistakes Outdoor Athletes Make With Sunscreen
Let's finish with a few common mistakes worth avoiding.
Mistake 1: Assuming Cool Weather Means Low UV
You can experience significant UV exposure when the weather feels cool, particularly at altitude or during bright spring and summer days.
Check the UV Index rather than relying on temperature.
Mistake 2: Applying Too Little
Using a tiny amount of sunscreen won't deliver the protection stated on the label.
Apply generously and evenly, following the specific product instructions.
Mistake 3: Forgetting the Ears, Neck and Hands
These exposed areas can receive significant sunshine during sport, particularly cycling, running, golf and sailing.
Mistake 4: Thinking Water-Resistant Means Waterproof
Even highly water-resistant sunscreen can be reduced by swimming, sweating and towel drying.
Reapplication remains essential.
Mistake 5: Only Thinking About Sunscreen on Race Day
Outdoor training often involves far more hours of sun exposure than the event itself.
Build sensible sun protection into your regular training routine, not just your biggest adventures.
Sun Protection Is Part of Your Equipment
Think about how much effort you put into choosing the right sports equipment.
Running shoes that fit properly.
Cycling clothing that wicks away moisture.
A hydration pack that doesn't bounce around.
Goggles that don't leak.
We choose these products because they help us enjoy our activities and perform comfortably.
So why should sunscreen be an afterthought?
For outdoor athletes, sun protection is an essential part of preparing for the conditions ahead.
And with EVY Technology's patented Swedish mousse, extra water-resistant formulation, five-star UVA rating and skin-barrier-supporting properties, you've got a sunscreen designed with active lifestyles in mind.
From a gentle Sunday walk to an ocean-crossing adventure, your skin deserves protection that takes the conditions seriously.
Because the best adventures are the ones you can keep enjoying.
Train hard. Explore further. Live life boldly.
