Race participation grew across every major distance in 2025, from 5Ks to full marathons, according to Running USA. Fall carries a big share of that growth. The heat has broken, the mornings feel crisp, and race calendars fill up fast between Labor Day and Thanksgiving.
We’ve helped thousands of teams, families, and companies design custom running shirts for their 5K, 10K, and half marathon crews over the years. Here’s what actually works for race day, cold mornings, and everything else your group needs to look like a team at the finish line.

Key Takeaways
- Moisture-wicking fabric beats cotton on race day. Our most-reviewed running shirt, the Sport-Tek Competitor Performance Shirt, has more than 9,000 customer ratings, and it’s built entirely from quick-dry polyester.
- Race participation is climbing across every distance. 5K, 10K, half marathon, and marathon fields all grew in 2025, according to Running USA, so fall race gear demand isn’t slowing down.
- Group Order Form removes the size-chasing headache. Everyone on your team picks their own size and shipping address, so you’re not stuck collecting cash and re-mailing shirts.
Custom Running Shirts for Every Distance
Performance shirts are the backbone of race day. Moisture-wicking polyester dries faster than cotton and won’t cling to your skin at mile 10. We carry short sleeve and long sleeve custom performance shirts built for exactly this. The table below breaks down which style fits which kind of race.
| Style | Best For | Notable Feature |
|---|---|---|
| Sport-Tek Competitor Performance Shirt | Warm-weather 5Ks and 10Ks; the most-ordered option for mixed teams | 3.8 oz. polyester, more than 20 colors, youth sizes available |
| Hanes Sport Cool Dri Performance Shirt | Sunny outdoor events and charity walks | 4 oz. polyester with built-in UPF 50+ protection |
| Sport-Tek Women’s Competitor Performance Shirt | Teams wanting a fitted women’s cut | Contoured silhouette with a modified scoop neck |
| Sport-Tek Competitor Performance Muscle Tank | Hot-weather training runs and summer 5Ks | Sleeveless design for maximum airflow |

Corporate and Charity 5Ks: Team Gear That Builds Camaraderie
Plenty of fall races exist because a company or a cause organized one. Sponsoring a charity 5K or fielding a team for one is a simple way to get a group moving together. Matching shirts make the whole thing feel official.
“Our shirts turned out great! They were created for a 5K event that we helped to sponsor for Head for the Cure, a non-profit charity supporting the fight against Brain Cancer.”

Once you know your shirt, our Design Lab makes the rest easy. Start from a blank canvas or a template built for race day, then edit the words, fonts, colors, and art until it’s yours.
Design Inspiration for Race Day
Need a team name to go with the design? We’ve rounded up 5K team names, running team names, and half marathon sayings in separate posts with more ideas. If you’re not sure how to turn a sketch into a print-ready design, design help is available at no extra cost.
Group Orders and Fundraising for Your Cause
Once the design is locked, the logistics are what actually stress out race organizers. Our group order feature lets each runner pick their own size and shipping address. Nobody has to chase down sizes over text message. You can also let us collect the addresses for you, or ship everything to one place and hand out shirts on race morning.
- Best for teams under one roof: Ship to a single address and distribute shirts yourself at packet pickup.
- Best for scattered teams: Let each runner enter their own address so shirts arrive at their door.
- Pro tip: Order two to three weeks out. Our delivery options include rush service if your event snuck up on you.
Many fall races exist to raise money for a cause first and log miles second. Our fundraising platform lets you sell custom shirts and collect donations with no inventory to manage upfront. Design the shirt, share your story, and we handle printing, shipping, and sending you the funds raised.
Frequently Asked Questions
Q: How far in advance should I order custom race shirts for my 5K or 10K?
Orders arrive within 2 weeks with free standard shipping. Rush options are available for an additional charge if your event is coming up fast. See our delivery options for specific turnaround times.
Q: Can I order just one custom running shirt, or is there a minimum?
Many performance shirts have low or no minimums, so a single runner can order one shirt just as easily as a 50-person team. Check the product details or filter by no minimum to confirm.
Q: Are bulk discounts available for custom 5K and 10K shirts?
Yes. We offer discounts for bulk orders, and pricing drops automatically as you increase quantity. Check the product details or adjust the order quantity to see team pricing.
Q: Can each runner on my team pick their own size and pay separately?
Yes, through our group order feature. Each runner enters their own size and shipping address. Or pay for the whole order at once and ship it to one location.
Q: Can I get help designing my race team’s shirts?
Absolutely. Our design experts can help you build the perfect design. Our Design Lab also includes templates and clipart built for races and running events.
Q: What’s the best fabric for a fall 5K or half marathon?
Moisture-wicking polyester is the standard choice for race day because it dries faster than cotton and won’t chafe over long distances. For cold starts, layer a long sleeve performance shirt or quarter zip over your race-day tee and shed it once you warm up.
Q: Can I use Custom Ink to fundraise for my charity 5K?
Yes. Our fundraising platform lets you sell custom shirts and accept donations with no inventory to manage. We handle printing and shipping, and you keep the funds raised.
