Show off your love for running with this fun and quirky black t-shirt! The shirt features the text "On a Scale of 1 to 10 I'm 13.1" in eye-catching lettering. The numbers are styled with a whimsical, brain-like design in teal, orange, and pink. Made from what appears to be a soft and comfortable material, this tee is perfect for casual wear, workouts, or post-race celebrations. Let everyone know you're a proud marathoner (or half marathoner!) with this conversation-starting piece. A great gift for the runner in your life!
