Comfortable temps, moderate wind

Starting at 65°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Moderate winds around 14mph may affect pacing on open sections of the course. Moderate humidity at 68% is worth noting for effort level, especially in later miles.

About the Emerald Isle Half Marathon

The Emerald Isle Half Marathon starts and finishes at the Western Ocean Regional Access parking lot on North Carolina's Crystal Coast. The USATF-certified keyhole course follows the Highway 58 bike path and loops through the side streets near Old Ferry Road, Sound Road and Archers Creek before returning along the ocean side of the island. It is flat and fully paved, with the high point under 9 meters above sea level, and none of it is on sand.
