A race logo is a good starting point. It gives us a reference for the event name, color direction, theme, and overall style. From there, we can discuss how the logo might work on a medal, whether the design needs to be simplified, and how the ribbon or race T-shirt can match the same look.
If your logo is low resolution, still send it. A JPG, PNG, or screenshot can help us understand the direction. For final production, cleaner artwork may be needed, especially if the logo has small details, thin lines, or text.
If you have vector artwork, send that too. Vector files are usually best for production because they can be scaled and adjusted more cleanly.
