Most sunscreens are not built for athletes. They are built for a day at the beach, a walk to the farmers market, or a drive with the windows down. Apply them to someone training for hours in the heat and they are gone within the first 20 minutes.
Athletes need something different. Here is what to look for, and why it matters.
The Problem with Regular Sunscreen for Athletes
Standard sunscreens are FDA rated for 40 or 80 minutes of water resistance. For someone running a half marathon, cycling a century, or competing in a triathlon, that means your protection has expired before you even finish warming up.
Beyond water resistance, athletes face sweat, friction from clothing and gear, and extended UV exposure that most sunscreen formulas are simply not designed to handle.
What Makes a Sunscreen Actually Work for Athletes
There are three things that separate a genuine sport sunscreen from a regular one when it comes to athletic performance:
-
Water and sweat resistance that lasts through the duration of training or competition, not just 40 minutes
-
A formula that does not run into the eyes, which causes burning and distraction at the worst possible moment
-
Broad spectrum UVA and UVB protection, because athletes accumulate serious UV exposure over a season
The SolRX Waterblock Standard
SolRX worked with AMA Testing Labs to develop a water resistance test that went beyond FDA requirements. The standard SolRX set: prove the formula maintains its SPF rating after 8 hours of continuous water immersion.
AMA Labs confirmed it. SolRX Waterblock lotion sunscreens maintain 97% or more of their SPF protection after 8 hours in the water. No other sunscreen on the market has matched that standard.
For triathletes, open water swimmers, surfers, and anyone competing in multi-hour outdoor events, that is the difference between protection and false confidence.
Broad Spectrum Protection for Serious UV Exposure
Athletes who train outdoors accumulate significantly more UV exposure than the average person. UVA rays cause long-term skin aging and damage, UVB rays cause burning. Both contribute to skin cancer risk over time.
Every SolRX formula is broad spectrum, protecting against both UVA and UVB rays. This is not optional for athletes. Cumulative sun exposure adds up over a career of outdoor training, and the protection you use every day is an investment in your long-term skin health.
Reef Safe for Athletes Who Train in the Ocean
Swimmers, surfers, triathletes, and open water athletes spend hours in and around natural water. The sunscreen you wear matters for the ecosystem as much as it does for your skin.
SolRX formulas are oxybenzone free and octinoxate free, the two chemical filters most strongly linked to coral reef damage. Because Waterblock technology keeps the formula on your skin rather than washing into the water, SolRX is one of the most reef-responsible choices available for water-based athletes.
Formats for Every Sport
Different sports call for different application methods. SolRX offers lotions for full body coverage and extended water resistance, sprays for quick application during transitions and reapplication mid-activity, and zinc sticks for precise face and nose coverage without any runoff.
The Waterblock 8-hour protection is specific to the lotion formulas. For serious water exposure, the lotion is the right choice. The sprays are ideal for everyday training and reapplication.

Frequently Asked Questions About Sport Sunscreen for Athletes
What is the best sunscreen for athletes?
The best sunscreen for athletes is a broad-spectrum, water-resistant formula with SPF 50 that stays on through sweat and extended activity. The two critical requirements are a water and sweat resistance rating of at least 80 minutes and a formula that does not run into the eyes during intense effort. SolRX Waterblock lotion sunscreens are independently tested by AMA Laboratories and confirmed to maintain 97% or more of their SPF rating after 8 hours of water immersion -- the highest water resistance standard in the market.
What is the difference between sport sunscreen and regular sunscreen?
Sport sunscreen is formulated to stay on through water, sweat, and friction -- conditions that quickly degrade regular sunscreen. Regular sunscreen is designed for low-activity sun exposure like sitting outdoors or driving. Sport sunscreen uses bonding technology that adheres to the skin surface rather than washing off, maintaining its SPF rating through physical activity. SolRX Waterblock technology bonds to the skin surface on application, creating a UV barrier that stays intact through water immersion, sweat, and extended wear.
What SPF should athletes use?
Athletes should use SPF 50 as the standard. SPF 50 blocks approximately 98% of UVB rays compared to 97% for SPF 30. The difference seems small but becomes significant over the cumulative UV exposure athletes accumulate across a season. For athletes training at high altitude, near reflective water or snow, or during peak UV hours between 10 AM and 2 PM, SPF 50 is not optional.
How often should athletes reapply sunscreen?
Athletes should reapply sunscreen every 2 hours during prolonged sun exposure, and immediately after towel drying. Even water-resistant formulas lose effectiveness over time and with physical contact. For standard sport sunscreens rated at 80-minute water resistance, reapplication is required after each 80-minute water exposure period. SolRX Waterblock lotion formulas are tested to 8 hours of water resistance, significantly reducing the reapplication frequency for water-based athletes.
Does sunscreen affect athletic performance?
No. Research has shown that neither mineral nor chemical sunscreens affect core body temperature or perceived discomfort during exercise. The concern that sunscreen causes overheating is a myth. The real performance consideration is choosing a formula that does not run into the eyes during sweating, does not leave hands greasy affecting grip, and does not require constant reapplication during training or competition.
Is mineral or chemical sunscreen better for athletes?
Both can work effectively for athletes. Mineral sunscreens use zinc oxide or titanium dioxide to physically reflect UV rays and sit on top of the skin. They are reef-safe and do not absorb into the bloodstream. Chemical sunscreens absorb UV rays and convert them to heat. For water-based athletes, the key factor is water resistance performance rather than mineral versus chemical. SolRX offers both mineral and chemical sport formulas, all oxybenzone-free and reef-safe.
What sunscreen do professional athletes use?
Professional athletes in water sports, triathlon, cycling, and outdoor endurance events typically use high-performance sport sunscreens with extended water resistance. SolRX Waterblock is used by competitive swimmers, surfers, triathletes, and outdoor endurance athletes who require all-day protection without constant reapplication. The 8-hour water resistance standard was developed in collaboration with AMA Laboratories specifically to meet the demands of multi-hour competition.
Should athletes use reef-safe sunscreen?
Yes, especially for water-based athletes who compete or train in oceans, reefs, or coastal environments. Oxybenzone and octinoxate, two common chemical UV filters, have been linked to coral reef bleaching and are banned in Hawaii, Palau, and other reef-protected destinations. Athletes competing in events at these locations are required to use compliant formulas. SolRX formulas are free from both oxybenzone and octinoxate and are Hawaii Act 104 compliant.
What is the best way to apply sunscreen before sport?
Apply sunscreen 15 minutes before activity to allow the formula to bond with your skin. Use at least 1 ounce for full body coverage -- most people apply significantly less than needed. Apply to all exposed areas including the back of the neck, ears, tops of feet, and backs of hands. For the face, apply carefully around the eyes. Use a zinc stick for precision coverage on the nose, ears, and around the eyes where runoff from sweat is most likely. Do not apply immediately before water entry -- allow the formula to set first.
Does sunscreen wash off in the pool or ocean?
Standard sunscreens do wash off with water exposure. The FDA requires any sunscreen claiming water resistance to specify either 40 minutes or 80 minutes -- these are the two recognized standards. Beyond 80 minutes, the standard water resistance claim no longer applies. SolRX Waterblock technology has been independently tested and documented by AMA Laboratories to maintain SPF protection for 8 hours of continuous water immersion. That means the formula stays on rather than washing into the water, which also makes it more reef-responsible for ocean athletes.
