Why Custom One?
Choosing the Right Print Method for Your Race Tee
When creating a custom marathon t-shirt design, durability and comfort are essential. At Custom One Online, we offer top-tier printing techniques to match your needs. Screen printing is perfect for bold, vibrant team logos that need to withstand sweat and long hours on the road. It’s one of the oldest and most reliable techniques in the industry — learn more about its process on Wikipedia.
For designs with intricate details, photos, or gradients, we recommend Direct to Garment (DTG) printing. This method delivers sharp, photo-quality images on 100% cotton tees, making it ideal for detailed marathon memorabilia. DTG is gaining popularity fast — here’s why.
Want to print on a wider variety of materials, including performance fabrics? Direct to Film (DTF) printing is a game-changer. It offers flexible application across surfaces and is known for its long-lasting color and stretch resistance — even under marathon-level sweat and movement.
Team Spirit & Group Orders for Marathons
Share information about your brand with your customers. Describe a product, make announcements, or welcome customers to your store.
Custom T-Shirts for Race Events and Sponsors
Marathons are high-visibility events — the perfect stage for brand exposure. Whether you’re promoting a race sponsor or marketing a new athletic product, custom t-shirts become mobile billboards during and after the race. Our team works with event planners, businesses, and non-profits to create eye-catching tees that runners love to wear again and again.
We use Heat Transfer Vinyl for logos with metallic, neon, or specialty finishes. This method ensures sharp edges and vibrant detail that stand out in race photos and social media posts. Explore the technology behind it on Wikipedia.
Our team can even handle art repair and review to ensure your sponsors' logos appear clear and polished on all merchandise. From dry-fit fabric options to classic cotton tees, we’ll help you create merch that promotes your brand while enhancing the athlete’s experience.
Personalized Marathon Shirts as Keepsakes
Every marathon has a story. From first-timers hitting a personal milestone to seasoned pros qualifying for major races, your shirt is a wearable memory. At Custom One Online, we help runners personalize their apparel with names, race times, dates, and even motivational phrases that inspire them long after race day.
Looking for performance-based materials or ultra-soft fabric blends? Our product range includes custom t-shirts, long-sleeves, and even tank tops perfect for post-race lounging. We make it easy to customize online with real-time previews, and offer same-day shipping to keep your timeline on track.
If you’re not sure where to start, our support team can walk you through fabric choices, fit recommendations, and optimal print placements. We turn every idea — from simple names to complex graphics — into a shirt you’ll proudly wear for years to come.
