ALTAMONTE SPRINGS, FL — The Reindeer Run & Roll 5K by CORE is bringing an extra dose of holiday magic to this year’s race with color-changing medals and color-changing shirt designed and produced by X T-shirt.
Just like the holiday spirit that brightens the season, this year’s race swag transforms under sunlight — with the reindeer changing from classic white to festive red. The effect captures the energy and warmth of the holidays while giving runners a memorable keepsake that comes to life outdoors.
“Our goal was to create something that truly feels like the holidays,” said Ryan Zhu, founder of X T-shirt. “The reindeer turning red in the sunlight symbolizes the joy and excitement that the event brings to the community — a fun, interactive surprise that runners can enjoy beyond race day.”
The medals and shirts were both custom designed to match the Reindeer Run & Roll 5K’s family-friendly and inclusive atmosphere, celebrating the season through creativity and color. Each design integrates playful winter motifs and cheerful hues, making them perfect for race photos, social sharing, and holiday celebrations.
The Reindeer Run & Roll 5K will take place on December 13, 2025, in Altamonte Springs, Florida, inviting runners, walkers, and rollers to join in the festive fun.
