Official runDisney Costume Guidelines for the 2026 Princess Half Marathon Weekend

The Disney Princess Half Marathon at Disney World is officially set for Sunday, March 1, as part of the larger race weekend running from Feb. 26 through March 2. With the big day just around the corner, ensuring your royal attire meets the safety standards is key to a stress-free start.

Below is the list of guidelines provided by runDisney to help you prepare:

• Costumes must be family-friendly and may not be obstructive, offensive, objectionable or violent.
• Participants 14 and older may not wear costume masks of any kind.
• Participants 13 and younger may wear costume masks, however, the participant’s eyes must be visible and the mask may not cover the participant’s entire face.
• Participants who dress like characters may not pose for pictures or sign autographs for other guests except as expressly requested and authorized by runDisney.
• Costumes may not drag on the ground.
• Costumes may not contain sharp objects, pointed objects or materials that may accidentally strike another participant.
• Costumes may not contain any weapons which resemble or could easily be mistaken for an actual weapon.
• Layered costumes, such as ball gowns, hoop skirts, those that have an infrastructure with metal components or hard edges, costumes that do not follow the natural contour of the human body, and/or costumes that could conceal prohibited items are not permitted.  
• Layered clothing, including tutus over running shorts, cold-weather gear such as sweatshirts or sweatpants, and clothing that follows the natural contour of the body are permitted unless they present a safety hazard (e.g. dragging on the ground). 
• Costumes or large props including, without limitation, items that present a safety hazard (e.g. King Triton’s trident), those that surround the entire body (e.g. cardboard, plastic or other wearable costumes with hard edges, such as a house from Disney-Pixar’s Up), those that are inflatable, or those that physically connect multiple participants to each other are not permitted. 
• Small, inflatable or soft-bodied, handheld props (e.g. an inflatable Toy Story ball) are permitted. 
• Tutus, transparent wings, and hats/headwear are permitted, however, they may not cover the participant’s face.
• Capes may be worn if the length does not go below the waist.
• Themed T-shirts, blouses, sweatshirts and hats are acceptable.
• Participants who do not adhere to these guidelines may be refused entry into, and/or removed from, a runDisney event unless their costume can be modified to meet the above standards.
