Custom 5K Race & Running Shirts: The Ultimate Guide for Race Day Success
Planning a 5K race, sponsoring a run, or gearing up your team for race day? Whether you’re organizing a charity event, corporate wellness run, school fundraiser, or competitive race, custom 5K running shirts are one of the most important (and visible) parts of the experience.
At Broken Arrow T-Shirt Printing and Embroidery, we help customers create custom running shirts that runners actually want to wear—on race day and long after the finish line. Below is your complete guide to designing custom race day running shirts that look amazing, feel great, and help your event stand out.
Why Custom 5K Running Shirts Matter More Than You Think
A great race shirt isn’t just a freebie—it’s a walking billboard, a performance tool, and a keepsake all rolled into one.
✔ Builds excitement before the race
✔ Creates team unity and brand recognition
✔ Improves runner comfort and performance
✔ Markets your race long after the event ends
When runners love their shirt, they wear it again—and that means more visibility for your race, sponsors, and cause.
1. Choose the Right Shirt: Performance Matters on Race Day
Not all t-shirts are created equal—especially when running is involved.
Best Fabrics for Custom Running Shirts
Look for performance or moisture-wicking shirts, often called:
- Performance
- Endurance
- Dri-Fit
- Cool-Dry
- All-Sport
- Dry Zone
- Double Dry
These shirts are typically made from 100% polyester or polyester blends, specifically engineered for running and working out.
Why Polyester Wins for Running Shirts
Modern polyester is nothing like the heavy, sweaty fabric of the past. Today’s high-tech weave:
- Pulls moisture away from the skin
- Evaporates sweat quickly
- Reduces chafing
- Stays lightweight even when wet
Fun fact: Polyester absorbs only 0.4% moisture, while cotton can hold up to 7%—which is why cotton shirts feel heavy and uncomfortable during a race.
Bonus: Performance shirts are wrinkle-resistant, shrink-resistant, and built to last.
2. Match the Shirt Style to Race Day Weather
Weather can make or break race comfort—plan accordingly.
Shirt Style Recommendations
- Hot weather: Short sleeve athletic shirts, racer-back tanks, or running tanks
- Cool weather: Long-sleeve moisture-wicking race shirts
- Unpredictable weather: Layer with a custom full-zip performance hoodie
Pro tip: Many races offer multiple shirt options during registration for an upgraded runner experience.
3. Get the Sizing Right (Your Runners Will Thank You)
Nothing kills race-day vibes faster than an uncomfortable shirt.
Broken Arrow offers:
- Men’s sizes
- Women’s sizes
- Youth sizes
- Unisex options
- Extended sizes up to XXXXL and tall sizes
Best Practice for Race Organizers
✔ Collect shirt sizes during registration
✔ Order a few extras for late sign-ups
✔ Offer women’s-cut shirts when possible
Comfort = happy runners = better reviews next year.
4. Design a Custom Race Shirt People Actually Want to Wear
Your design should be bold, readable, and meaningful.
Design Tips That Work
- Choose shirt and ink colors with strong contrast
- Make text readable from across the street
- Avoid clutter—clean designs perform better
- Highlight your race name, year, or cause
Brainstorm With Your Team
Ask:
- What word defines your group? (Fierce, Hopeful, United, Determined)
- What symbol represents your cause? (Heart, ribbon, flag, animal, city skyline)
- Is your race serious, fun, or somewhere in between?
A memorable design turns your custom running shirt into a favorite go-to workout tee.
5. Print Front and Back for Maximum Visibility
For custom race day running shirts, placement matters.
This ensures your event is marketed from every angle—before, during, and after the race.
6. Encourage Runners to Wear, Share & Repeat
Your race doesn’t end at the finish line.
Boost Post-Race Exposure
- Encourage runners to wear their shirts on race day
- Take group photos before and after the race
- Share images on social media and tag participants
- Encourage runners to tag your race and sponsors
