10 miles. About 8 of them are on bike lanes, through the park, or on the bridge. Only the last 2 miles in Manhattan are in the street in traffic. It is pretty amazing to me that I can go that far without being in a car lane in NYC. Those last 2 miles on 1st Ave are slated to get a bike lane as well, but it may take a little while. On the way back home, I have another mile or so of bike lane on 2nd Ave.
It takes under an hour if the lights are in my favor. I'm not one to blast through intersections like some of the crazies do, but I'll soft pedal through a red if there's nobody coming. I better watch that when I get to Seattle next week since nobody does that there. It takes me 45-50 minutes on the subway so it is basically a wash, bike vs train.
I've thought about trying a longer route home to get more miles in, but the best place for me to get more miles is in Prospect Park by doing a few extra laps. But every time I consider that I decide that I'd rather go home and get my road bike for that since that is the very end of my ride. Then reality hits when I have 3 hungry teenagers when I walk in the door.
