NYRR Open Run turns a neighborhood park into a free 5K every week, and St. Mary's is one of the better courses for it: rolling hills, grand old trees and a stretch of the South Bronx that was once part of Jonas Bronck's estate. It is volunteer-led and genuinely open — walkers, strollers, first-timers and fast regulars all set off together from East 149th Street and Eagle Avenue. If you want a running habit without a race entry, start here.
What to expect
Gather near the East 149th Street and Eagle Avenue entrance, where volunteers handle a short briefing and send everyone off together. The course takes in the park's hills, so expect honest climbs rather than a flat time trial, and expect to pass people and be passed. Runners hang around afterward far more than they would at a timed race.
Good to know
- The 6 at East 143rd Street–St. Mary's Street and the 2 and 5 at Third Avenue–149th Street are both a short walk.
- Sign up once through the NYRR Open Run page linked from the NYC Parks listing.
- It is walk-friendly, so pace anxiety is misplaced — plenty of people finish on foot.
- The course rolls; flat-course legs will notice the hills, but no special shoes are needed.
- The park has a pool, playground and courts, so it works as a family staging ground while one adult runs.

Do I have to run the whole 5K?

Do I need to sign up in advance?
NYC Parks links to an NYRR sign-up page. Registering ahead is the smoothest route, so check that page for the current requirement.
