Copperfield 5K Cold Run 2025 Debuts Color-Changing Medal

October 9, 2025

October 7, 2025 /ENDURANCE SPORTSWIRE/ – The Copperfield 5K Cold Run, set for October 11, 2025 in Louisville, KY, is adding extra excitement to this year’s event with a color-changing finisher medal designed and produced by X T-shirt.

Medal Tells the Story

The medal, shaped like a house to reflect the Copperfield neighborhood, transforms under sunlight:

• Indoors it appears cool and neutral.
• In sunlight it shifts to a warm red body with an icy blue “Cold Run” panel.

The color transition mirrors the race’s name and its support for Cold Capping therapy, highlighting both the energy of the runners and the cause behind the event.

“We wanted the medal to feel alive and meaningful,” said Ryan Zhu, founder of X T-shirt. “Its transformation under sunlight connects the race experience with the community’s spirit and the purpose it serves.”
