1st Avenue

Our loose end tour of Manhattan harkens back to our walk of Midtown, where we marched up and down the gridded streets to cover every scrap of territory. This time we're on the Upper East Side, where we somehow missed many of the avenues that parallel Central Park. We'll go from 1st to Madison, then head down to the mid-forties to hit some of the cross streets we missed earlier in the year.

Our walk this week traverses the many bridges that connect Manhattan to all parts east. Starting with the Ed Koch/Queensboro bridge, we snake through Randalls Island before systematically tackling the nine bridges that connect Upper Manhattan to the Bronx. Not included in this map due to route revision constraints are both the walk over the Third Avenue Bridge and the 2.5 miles from Henry Hudson Park to the train at 181st Street.

This week we tackle the most famous Green space in the city and possibly the world: Central Park. We'll cover it from tip to top, with detours to the shores of the Upper East and Upper West Side to see the sights and meet our daily mileage quota.

Our first look at Midtown pays homage to the grid that defines it. From 23rd to 59th Street, we walk up and down 1st to 11th Avenue until we reach our marathon limit. This includes too many sites to mention, from the Chrysler and Empire State buildings; the Theatre District and Times Square; Grand Central Station; Rockefeller Center and so much more.

This high-level sweep of North Brooklyn takes us around the edges of Bushwick, Greenpoint, Williamsburg, Brooklyn Heights and Red Hook. We do an about face in Sunset Park and head up 5th Avenue through Park Slope. After briefly touching the tip of Fort Greene, we meander through Bed-Stuy and Crown Heights before heading home.
