INDIANAPOLIS, IN — The Be My Valentine Run has always celebrated love, energy, and community — and in 2026, it’s adding a whole new layer of magic.
This year’s event shirt, designed and produced by X T-shirt, brings the theme of passion to life through color-changing and sweat-activated effects. Indoors, it starts as a clean pink base with a heart design. Under sunlight, that heart ignites into vivid flames — a symbol of energy and connection. As runners heat up, hidden phrases like “I’m On Fire,” “Hot Stuff,” “Light My Fire,” “Ring of Fire,” and “Eternal Flame” emerge across the fabric, revealing the emotion behind every mile.
“The idea was to let runners feel the theme, not just wear it,” said Ryan Zhu, founder of X T-shirt. “Magic Shirts transform events into experiences — they make every participant part of the story. When the shirt reacts to the sun or sweat, it creates moments runners can’t help but share.”
For race organizers, these shirts aren’t just apparel — they’re a built-in engagement engine. From pre-race social media teasers to post-finish photos, Magic Shirts add a layer of storytelling that boosts participation, sponsorship visibility, and post-event buzz.
The Be My Valentine Run returns to Indianapolis, Indiana, inviting runners to celebrate fitness and love in a fun, fiery atmosphere.
