Race Info

NO HILLS!! FLAT, BEAUTIFUL & the Last Boston Qualifying Course of the year! The route is on a beautiful gravel oceanside trail! This is one of those routes that is so scenic you almost forget you are running! We are talking BEEAUUUTIFULLL!!! All distances are an out-and-back design and the route is completely flat! The only challenge you are going to face is the weather and the fact you might run off the trail as you gaze at the ocean views! Source
