Flat and fast for sure! I haven't done this race specifically but I know the area and have been out on the course. I've heard stories about jellyfish/nettles being a possibility in some years. The race organizers are well experienced and first class.
Run is spectator friendly because its a short out and back multiple times.If I'm not mistaken the swim is point to point, which makes wind/current a factor (tidal river).Run by the same folks who do Eagleman, Columbia, etc... so despite Chessieman smaller size they know exactly what they're doing.FLAT. FLAT. FLAT.
