Name: Mackenzie Roy
Age: 32
From: Natick

I was born and raised in Natick and grew up watching the Boston Marathon. It was a family tradition before I was even born.

Fifteen years ago, while watching the race, I decided that one day I was going to run the Boston Marathon myself. After many years of struggling with autoimmune diseases, I finally reached a point where I was ready to do it.
