Sunday, April 10, 2022 • Key Biscayne, FL • Course Map
An “oasis of sandy beaches, nature preserves and restaurants with stunning views” lies just a short drive across the Rickenbacker Causeway from downtown Miami on this small barrier island that once was a coconut plantation — that’s where you’ll run the KB Bayside Half Marathon, which starts and finishes inside the island’s beautiful Crandon Park.
Runners start the out-and-back course for the race overlooking Crandon Beach, which lies just north of the town of Key Biscayne. From there, you’ll follow the park’s winding roads and trails as they run past the beach and snake around ponds, all the way toward the northern end of the island.
Between mile markers 4 and 5, you’ll run a brief out-and-back stretch along the Rickenbacker Trail, part of an 8 1/2-mile-long trail that runs across the Bear Cut Bridge and past the Miami Seaquarium.
Once you make it back to the causeway, you’ll stay on the trail and head north, running across the bridge and over to Historic Virginia Key Beach Park. There, you’ll run past piers and beach areas while staying on the trail until you hit the turnaround point, between miles 6 and 7.
After that, you’ll make the turn and retrace your steps all the way back across the Bear Cut Bridge and along the Rickenbacker Trail, all the way back to Crandon Park for the race finish.
