NYRR Open Run brings free, 5K weekly community-led runs, to neighborhood parks across the greater New York City area. The program is free and open to runners and walkers of all ages, abilities, and experience levels.St. Mary's Park offers a wonderful respite from the hustle and bustle of urban life. Located in the Mott Haven neighborhood in the South Bronx, the park features rolling hills, expanses of green grass, and grand old trees. The site was once part of the estate of Jonas Bronck (1600-43), for whom the Bronx is named. It is one of the largest parks in the area with a pool, playground, basketball courts, an indoor recreation center, picnic seating areas, and more. In the winter, the hills are perfect for sledding. St. Mary’s Park received $30 million from NYC’s Anchor Parks initiative, which will renovate the park’s ballfields, pathways, and amphitheater.
