Run as One 4 miler is a pretty easy and cheap qualifier for the 9+1 NYC marathon. The route takes place in central park, starting on the east side and looping around to the west side. I find this route is less hilly than the opposite direction.
The bib pick up was at the NYRR headquarters and bf went for me. The shirts are nicely designed and tech! No finisher medal for this four miles. Central Park is a nice run for scenery but for allergy sufferers like myself, meds are definitely needed. I took MTA to get here in the morning and that usually goes pretty smoothly. I wouldn't really recommend driving in the city anyways.
Plenty of water and spectators. A quick and enjoyable run.
