Last Sunday (Sept 11) I did the NYC Century Bike Tour 2005. Well, to be accurate, I did the 35 mile version anyway (15, 55, 75 and 100 mile versions were also options).
The ride took us down through Manhattan from the top of Central Park, over the Brooklyn Bridge, down to and around Prospect Park, up through Williamsburg, Greenpoint in Brooklyn then into Long Island City, Astoria, Randall’s Island and then back into Manhattan. Some crazies did the 100 mile version, which when contemplated after about 30 miles in that, to me was mindboggling. Next year, 55 for me, I think.
The whole thing looked like this when taped to a tree in Astoria Park, Queens. I did the Manhattan bit and then the green bit and back to Central Park.

I rode home from there, so it was about 40 miles in all, but that was me done for the rest of the day, I have to say. Still you get to see some parts of the city that you probably wouldn’t visit if you weren’t passing through on a bike, unless you were lost. There’s some more pictures of those sorts of places here.
