NYC Marathon watching

How is the marathon watching in Park Slope on 4th Ave? I've normally gone to the Upper East Side bars/restaurants to hang out for marathon watching. How is it in the Slope?

it's fun. we call it the 'math of humanity.'
thousands of people run by and you yell at them
then you go home and watch the finish on tv.

i think there's many longstanding brunch parties built around this activity

Good place to watch, 4th Ave side of Byrne Park (betw 3rd & 4th Sts)
then can brunch at restaurants nearby ... as 4th Avenue is a gastronomic wasteland. There's a water station for the runners at that location. It's approx. the 7 mile mark.
Always fun to watch the wheelchair guys come first, then the elite runners ... then it seems like you're waiting eternally for the rest of the pack. Since I live nearby always time it from when I see and hear the TV helicopters to run down and see the elites.
Another good view is at the top of the Slope - Atlantic Ave & 4th Ave intersection. And if you're up there follow the runners into Fort Greene after they pass BAM. Lafayette Avenue is a cool location. Narrow street.
If you're really adventurous follow them up through Billburg on Bedford Avenue, then to Greenpoint on Manhattan Avenue before they head over to Queens.

9th Street and 4th Ave near the elevated subway station is a great spot to watch because the Fire Dept usually has a truck and a cheering section right there. Makes for a lively crowd.
