Since I'll never run a marathon, I can't put one of those 26.2 stickers on my car.  BUT I do live in a Great Lakes State, so this vinyl is perfect.  This 4x4 vinyl is perfect for your car window ,laptop, or anywhere you want to stick it.  And hey, if you DO run marathons, get one of these stickers anyway.  The Label Vinyl is 4" wide x 4" tall.
