Donate an old race T-shirt !
Update!!!!
500 race T-shirt s were donated during the trail running weekend! We’re thrilled to share the amazing results of our recent collaboration with several trail running events on October 5-6. Thanks to the generosity of runners worldwide, we collected nearly 500 race shirts to support young people from low-income families in Peru’s Amazon region.
We want to thank the event organizers who made this possible: Douro Ultra Trail in Portugal, Thusy en Trail in France, and the Glasgow to Edinburgh Ultra (GB Ultra) in the UK. Their support and commitment were essential to this campaign’s success.
We will send all donated shirts to the Tangarana Social Platform, a charity that helps disadvantaged youth in the Peruvian Amazon through trail running. These shirts will provide attire for sports activities and symbolize the solidarity of the global running community.
Have an old running shirt gathering dust in your closet? No problem! Our collection is still active. When you pick up your bib at upcoming races, bring that shirt and support this project. TrailRunAdvisor ambassadors will collect donations and ensure they reach PS Tangarana.
This is only the beginning! Over the coming weeks, we’ll add more races to this initiative, so stay tuned to learn where you can keep contributing.
Thank you all for your incredible support! Together, we’re running for a great cause. Let’s keep the generosity flowing and bring hope to those who need it most.
Why choosing the right running shirt is key to success in running
Running goes beyond just being a sport; it’s an experience that challenges the body to perform consistently in all weather conditions. Choosing the right running shirt is essential for every runner, impacting not only comfort but also performance and overall race experience.
Running shirts are crafted to meet athletes’ specific needs. With features like breathability, ergonomic fit, and quick-drying materials, these garments help runners stay cool and comfortable. They reduce distractions caused by sweat or skin friction, allowing athletes to focus fully on their run.
In a race or marathon training, every detail matters. The shirt you wear can be the difference between optimal performance and an uncomfortable day. A proper shirt minimizes the risk of chafing and blisters, enhancing each mile of your journey.
Essential features of a good race t-shirt
Not all race T-shirts are created equal. A good running shirt should meet several key criteria that go beyond being lightweight or form-fitting. Here are the essential features to look for:
Breathable material: The best running shirts use synthetic materials like polyester or elastane blends. These fabrics absorb and evaporate sweat quickly, keeping you cool and preventing overheating during long runs.
Anti-chafing technology: Flat seams and tag-free fabrics help prevent chafing, especially in areas like the underarms or shoulders. This design reduces irritation from repetitive movement.
Ergonomic fit: A running shirt should fit comfortably without restricting movement. Proper fit allows freedom of movement and avoids air pockets that create drag or resistance while running.
Lightweight: Technical shirts are often ultra-light, promoting freedom of movement and minimizing weight during races.
Quick-drying: Quick-dry fabrics are essential since a wet shirt can cool you down too much in cold weather or feel uncomfortable in warm climates.
Each feature serves a purpose: helping runners focus on performance and fully enjoy the experience without distractions
Differences between race t-shirts and regular shirts
What you need to know: It’s easy to assume that any race T-shirt will work for running, but the differences between a technical running shirt and a regular cotton shirt are substantial. Here’s why running in a regular shirt isn’t the same:
Breathability: Cotton shirts retain sweat, making them heavier and less comfortable as your run progresses. In contrast, technical shirts wick moisture away, keeping you dry longer.
Weight: Technical shirts are generally lighter, allowing smoother movement. Since they absorb less moisture, they also avoid becoming heavy when you sweat.
Comfort: Regular shirts can cause friction and discomfort during long runs. Technical shirts solve this with optimized seams and soft fabrics that move with your body.
Durability: Running shirts are built to endure heavy use and frequent washing without losing shape or effectiveness, unlike cotton shirts, which wear out more quickly.
Choosing a technical shirt is an investment in both comfort and performance for any runner.
How to care for your race T-shirt to make them last longer
Once you find the perfect running shirt, it’s important to care for it properly so it lasts. Technical shirts need special attention to maintain their qualities. Here are some helpful tips:
Hand wash or use a gentle cycle: Avoid harsh washes and high temperatures. Wash by hand or use a delicate cycle in the washing machine.
Skip the fabric softener: Fabric softeners can damage the technical fibers, reducing breathability and effectiveness over time.
Air dry: It’s best to air dry your shirt instead of using a dryer, as heat can damage synthetic materials.
Separate by color: Wash technical shirts separately or with similar colors to avoid stains.
With proper care, your running shirts will last for many miles and maintain their original comfort and performance.
Solidarity project with Race T-shirt
Give your running shirts a second life and support youth in the Amazon One of the most impactful ways to make your old running shirts useful is by participating in charity initiatives like the one launched by TrailRunAdvisor in collaboration with the Tangarana Social Platform. This charity, dedicated to helping young people from low-income families in the Amazon region of Peru, uses trail running as a tool to foster social integration.
If you have a running shirt you no longer use, TrailRunAdvisor invites you to donate it when you pick up your race bib at participating events. A TrailRunAdvisor ambassador will be present at the event to collect the shirts, which will be sent to the Tangarana Social Platform. These race T-shirt not only help young people participate in sports activities but also represent an opportunity to empower them through sports, promoting values such as teamwork, personal growth, and respect for nature.
This type of initiative not only contributes to healthy physical and mental development for these young people but also connects them with the global running community, which has shown its commitment to solidarity. Donating a shirt may seem like a small gesture, but in the lives of these kids, it means an opportunity to feel part of something bigger, to grow in confidence, and to find new opportunities for integration.
The social impact of trail running is profound, and with projects like this, every runner can help improve the lives of young people who otherwise wouldn’t have access to these opportunities. So why let that old running shirt gather dust in your closet when it can make a difference in the Amazon?

Gerês Marathon – the last chance of the year to debut in mountain running
The Gerês Marathon is one of the most accessible mountain marathons in Portugal. It takes place inside Peneda-Gerês National Park, a natural paradise with granite peaks, deep valleys, waterfalls and ancient shepherd trails. Because it happens late in the year, many road runners choose this event as their first experience in trail running and mountain terrain. If you come from the asphalt world and want a smooth, friendly introduction to mountain events, this is one of the best options you will find. Why the Gerês Marathon is perfect for road runners 1. A runnable course Despite being a mountain marathon, most of the course is very runnable. Climbs are steady instead of steep, and technical sections are short. This helps road runners maintain rhythm and
