Sunday, April 16th, 2017 7:30 AMThe Brooklyn 15k brings in the spring at beautiful Prospect Park. The glorious heart of Brooklyn is the perfect event for the destination runner. The 15k has sold out four years in a row, and we expect to again in 2017. The B15 is a 3 loop course of rolling hills with giant tree-lined roads closed to traffic. In addition to the 15K, there is also a 10k, 5k and Kid's 2k run to offer a something for all category of runners and joggers.
