My Brooklyn Half Marathon experience was rainy - but incredible! The Expo was really just a giant party-type thing on a pier in Brooklyn. The course is hilly as it goes through Prospect Park but then flattens out as you run down Ocean Avenue. I think there were plenty of aid stations, but I was focused on finishing in the rain more than stopping at the stations. The race ends at Coney Island, and you get a recovery bag and a mylar blanket. If it hadn't been raining, I would have stuck around for the afterparty, but instead, I hopped on the subway so I could get back to my hotel and shower.
