Mild conditions, wind adjustments needed

Runners will face a steady temperature trend from 57°F at the start to 58°F at the finish, with humidity averaging 80%. A light headwind will challenge runners from miles 5 to 10, making pacing adjustments necessary during these segments. With wind gusts reaching 20 mph, it’s crucial to stay focused and conserve energy for the tailwind sections in the latter part of the race.

About the Smuttynose Rockfest Half Marathon

The Rockfest Half Marathon and its companion 5K run along the Atlantic coast at Hampton Beach, New Hampshire, each October. The USATF-certified half-marathon course is largely flat, gaining under 100 feet over its point-to-point route from Ashworth Avenue near B Street, along Ocean Boulevard past Hampton Beach State Park, and back along the water to a finish at the Sea Shell Stage. The 5K shares the same start and covers the race's opening three miles. Over 4,000 runners have combined for the half marathon and 5K in recent years, making it one of New Hampshire's largest annual road races.
