Cool start — fast day potential, moderate wind

A cool 47°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Moderate winds around 17mph may affect pacing on open sections of the course. Moderate humidity at 69% is worth noting for effort level, especially in later miles.

Race Info

The Rehoboth Beach Seashore Marathon runs each December in Rehoboth Beach, Delaware, pairing a full marathon with a half marathon on a flat, certified Boston-qualifying course. The route starts at the Bandstand on Rehoboth Avenue, crosses onto the Boardwalk, and heads north through Cape Henlopen State Park on the Gordons Pond Trail before the marathon turns around near the Cape May-Lewes Ferry terminal in Lewes. Both races finish on 4th Street behind Rehoboth Beach Running Co. Seashore Striders, a local running club, organizes the race, which has run most years since 2008 aside from a pandemic-related gap in 2020.
