Join Fitz Koehler as she welcomes Melissa, a brave and funny marathoner willing to share her unforgettable Boston Marathon experience. Melissa tells the God-awful tale of pooping her pants (in a very big way) while running the most iconic race in the world. It’s hilarious and stomach-churning while offering some insight so the same things don’t happen to you.
