St. Mary's Park is one of the largest green spaces in the South Bronx, a hilly former slice of Jonas Bronck's estate, and every week NYRR Open Run turns it into a free neighborhood 5K. This edition adds a chalk challenge, so kids and adults can cover the start and finish in color. If you want a low-stakes Saturday run with a real community feel, this is it.
What to expect
Participants gather at the St. Mary's Annual 5K start, decorate the line with chalk, then run or walk the course at their own pace. Volunteers keep it friendly, and families often stay afterward to use the park's playgrounds and lawns.
