Though the Boston Athletic Association advises Boston Marathon runners not to go overboard with heavy costumes (for security reasons), many make do with the rules in creative ways. This year, runners came out in all sorts of costumes, from spandex superhero garb to tutus to bunny ears.
Below, see a few costumed runners caught throughout the course.
1. Wonder Woman
2. A robot
3. A Patriots player / Captain America (?)
4. Dr. Doom
