The Key Biscayne Half Marathon at Crandon Park is designed to take runners over a spectacular and naturally scenic course in one of Florida’s most beautiful cities.  The 13.1 mile route will start and end at Crandon Park.  Runners will run along the Rickenbacker Causeway surrounded by lush tropical landscapes and superior ocean views.  At the midway point of the course you will experience the William B. Powell Bridge which will present a vertical challenge, but the views of downtown Miami and Biscayne Bay that it provides will be what takes your breath away.  Once back to Crandon you will run through the Old Zoo and finish along the Crandon Beach Boardwalk.
