Scurry to Hampton and see why Runner’s World dubbed the Sentara Crawlin’ Crab Half Marathon a must run half marathon. Complete with a snappy fast and flat course on the water, ample room for friends and family to cheer you on and a pumped up and picturesque post race celebration! The 13th running of the Sentara Crawlin’ Crab Half Marathon Weekend is the perfect place to run, crawl, and SHELLebrate (see what we did there?).
