Engineers' Gate: E90

Located at Fifth Avenue and 90th Street, this entrance to the Upper Reservoir Jogging Track is the place of choice for runners to enter Central Park. Adopted as the official entry point by the New York Road Runners Club whose offices are located nearby off Fifth Avenue, it is the place where runners can find information regarding runner events at the NYRRC kiosk.
It is also the gateway to the Reservoir Jogging Track with angled stairs located on either side of the gilded monument to John Purroy Mitchel.
The overlook above the memorial is the place where many runners do warm ups before and stretches after their run.
